This helps the solubility, as our tester noted that it mixes easily without any residue or floaties. You can have your pre-workout and keep it clean too with Transparent Labs BULK Black. This potent yet balanced formula is a great middle ground in the strong pre-workout space that helps you bring the noise while still hearing your own thoughts.

Overall, though, they enjoyed the flavor. Not only does Legion Pulse sport some excellent flavors, but it also contains a potent blend of active ingredients. Supplements are only helpful if you actually take them.

Though some people may find the sensation off-putting or downright uncomfortable, there are some gymgoers who love the skin tingling feeling of a big dose of beta-alanine kicking in.

If you count yourself among the latter, then Transparent Labs BULK Black is worth checking out. Beta-alanine is most commonly known for its potential to improve muscular endurance. The sensation itself is harmless, though some find it pleasurable while others may find it uncomfortable.

Get ready for the feel of bees buzzing on your skin, folks. In addition to the hearty dose of beta-alanine, this product is a well-rounded and properly dosed pre-workout overall.

Despite the large doses, the serving size is smaller than many other similarly potent pre-workouts at 21g per serving, making this a bit more palatable too.

A heavy dose of 4,mg of beta-alanine coupled with all of the other ingredients in this robust formula makes for a great pre-workout overall, tingles included.

Strong pre-workouts provide many of the same potential benefits that regular pre-workouts provide, only more so because of the increased potency of the formulas used.

They offer more energy, higher doses of ingredients, and often an improved value over run-of-the-mill pre-workouts.

Here are some pre-workout side effects and benefits you can expect. If regular pre-workouts provide a jolt of energy , then the strongest pre-workouts can be compared to tapping into the power grid itself with their higher caffeine and stimulant content.

Generally, pre-workouts contain mg to mg of caffeine per serving, which is about equal to one or two cups of coffee. The strongest pre-workouts like those on this list contain mg to mg on average.

Some are even higher than that for a massive dose of stimulants to potentially provide the most energy possible. For those who are caffeine sensitive, though, there are plenty of pre-workout alternatives you can try. Along the same lines as the caffeine content, strong pre-workouts tend to contain higher doses of other popular ingredients, which can make them potentially more effective.

The downside of this is that the scoops and serving sizes are larger — with some being the size of a scoop of protein powder — which some folks might not like. Pre-workouts vary in price for various reasons, such as the ingredients, dosing of those ingredients, and sometimes the brand name.

A container can look expensive up front but provide a ton of servings, making it more cost-effective than a cheaper priced tub with fewer servings. There are a ton of ingredients that companies put in their pre-workout products with claims to boost mental focus, energy, endurance, and blood flow.

Alpha glycerophosphocholine, also known as alpha-GPC, is a precursor to acetylcholine, which is a neurotransmitter involved in memory, attention, and most importantly here — muscle contraction. Taking between mg and mg of alpha-GPC can have nootropic effects, such as cognitive enhancement and improved focus, as well as potential improvements in muscle power output.

Beta-alanine is linked to improved endurance, both in cardio-focused workouts and strength training with higher reps. The standard dose is 1,mg to 3,mg, though the pre-workouts on this list can have upwards of 4,mg. This ingredient is commonly found in red beets and is the main ingredient in beetroot extract — though it can also be found in lesser amounts in leafy greens.

Caffeine is usually the main stimulant and has well-established potential ergonomic effects, such as better endurance, lower perceived exertion, improved power output, and even enhanced cognition. Creatine is likely the most thoroughly researched ergogenic aid aside from caffeine.

It can help power output, anaerobic capacity, fatigue, and even improve cognition all while increasing muscle size by potentially drawing more water into your muscles depending on the type of creatine you use. The dose is generally five grams per day of creatine monohydrate — though different forms, like creatine hcl, have smaller effective dose sizes.

Research suggests, the effective dose of citrulline is around 5,mg to help potentially improve blood flow, performance in endurance, and power output.

The pre-workouts on this list generally have higher dosing than that — even up to double for products with an emphasis on pump and blood flow. These sorts of products can make some folks a little concerned about side effects and unintended consequences. Caffeine is a real drug, and thus, can have some real side effects if you take too much of it.

It can cause anxiety, diarrhea, and maybe even temporary high blood pressure in mild cases of ingesting too much with more severe consequences coming from upwards of 1,mg over a short time.

Rather, everyone has a different tolerance for caffeine. Caffeine can make it harder for you to relax or disturb sleep patterns if taken close to bedtime. Keep in mind all the sources of caffeine you have throughout the day. One of which is beta-alanine whose minimum effective dose is somewhere between 1,mg and 2,mg.

This can cause a harmless yet somewhat uncomfortable sensation of skin tingling called paresthesia. Another ingredient to look for is citrulline — a common ingredient in nitric oxide supplements — which has been shown to be effective at improving blood flow during exercise with as little as 3,mg, though doses of 5,mg to 8,mg are more often recommended.

It can be quite easy to accidentally double up on an ingredient without knowing it and experience some potentially negative side effects. If the products are spread out compared to all at the same time, then it might be okay to have a bit over the normal amount of certain ingredients.

Just like most supplements, it depends on the person. You may have to throw on your lab coat and experiment for yourself. Most supplement companies that make strong pre-workouts like the ones on this list recommend starting with a half a scoop to assess your tolerance.

The more you know, the better informed you will be about the potential effects and how the formula works for you. This is especially key with potent doses like the ones on this list. Pre-workouts can be a great way to get that extra kick you need to make your way to the fitness center or focus up in a crowded gym.

These stronger-than-average formulas are more potent, and thus, can potentially elicit greater effects than more basic pre-workouts. That said, these are for experienced lifters who have been taking supplements for years and need the extra boost to gain an edge, or simply for it to be effective anymore.

That said, these supplements are generally considered safe when used as directed for those who are in good health with no pre-existing conditions.

We like Transparent Labs BULK Black for its high doses of nearly all the ingredients that people are looking for in a pre. It also has a well-balanced profile and is reasonably priced, which makes it a great choice for a strong pre-workout.

These more potent pre-workouts are for those who have been taking regular pre-workouts for a while and have built up a tolerance to the ingredients, no longer experiencing the same potential effects as they used to.

Keep in mind that caffeine has a half-life of around five hours in healthy individuals. This is because it can potentially enhance the effects of caffeine, which can cancel out the possible relaxation effects theanine normally has. The amount of caffeine in a pre-workout varies from one product to the next.

The strong pre-workout supplements we picked range from mg of caffeine to mg. So, for the most part, you can expect a strong pre-workout to have at mg of caffeine or more. Mike is an all around strength sports enthusiast who holds a B.

Deciding on the 18 best pre-workouts was no easy feat. We weighed the pros and cons of each product after analyzing these factors and using our GGR supplement testing methodology :.

Are important ingredients like caffeine, creatine, citrulline, citrulline malate, and beta-alanine included? Are there high levels of stimulants that have been shown to have detrimental effects?

Stimulants to keep an eye out for: High levels of caffeine, dendrobium, synephrine, DMAE, rauwolfia vomitora. This is subjective, but we base it on the views of our testers, as well as what the general consensus is in online customer reviews.

We took the individual flavor and full range of flavors into consideration. How well does this product dissolve in the suggested amount of liquid? Are there floaties? Is it grainy? Is it super thick or super thin?

Does it separate after a few minutes? What do customers think of the product? Are reviews consistent? Does the company interact with customer reviews?

If not, you might as well buy a more affordable supplement. This is particularly important for pre-workouts, because overloading on stimulants can be dangerous. Caffeine is a stimulant that targets the central nervous system, helping to support increased mental alertness while reducing the perception of fatigue Additionally, it can increase fat oxidation and spare muscle glycogen levels Creatine is a naturally occurring substrate that aids in energy production.

When taken as a dietary supplement, creatine has been shown to promote increased muscle strength, muscle size, speed, and high-intensity exercise capacity 8.

Nitric oxide supports improved blood flow via vasodilation widening of blood vessels Citrulline malate is a compound that combines citrulline with malate, a substrate essential for the production of energy needed for muscle contractions.

Citrulline malate has been shown to help delay muscle fatigue and increase oxygen delivery to muscles 3. Beta-alanine is a non-essential amino acid that binds with histidine to form carnosine. In your muscles, carnosine acts as a hydrogen ion buffer to help delay fatigue and improve high-intensity exercise performance 4.

Wondering why you should consider drinking a pre-workout before your next sweat session? Some benefits include:. Pre-workouts are probably best known for their ability to support increased energy and focus during workouts. Caffeine is well-known for its ability to boost energy and endurance levels during intense workouts 12 , and nitric oxide boosters like citrulline 15 and beetroot extract 17 can promote blood flow, which may result in more oxygen and nutrients being delivered to your muscles to maximize performance.

Pre-workouts can enhance strength in several ways. For one, they can provide you with more energy so that you hit your workouts harder and increase your training volume.

But, perhaps the most important ingredient for increasing strength is creatine. Creatine, which is present in some pre-workouts, aids in energy production during short, intense efforts and has been shown to increase strength when combined with resistance training in numerous research studies 7.

Ingredients like L-Theanine 5 , Rhodiola rosea 13 , and L-Tyrosine 6 can help you stay focused and motivated throughout your workout. Nootropics like these have also been shown to enhance memory, attention, and concentration 9.

One way to boost stamina during your workouts is to combat feelings of fatigue. Supplementation with beta-alanine 4 has been shown to increase intramuscular stores of carnosine. Carnosine works as an intracellular buffer to reduce the accumulation of hydrogen ions— ultimately delaying fatigue Caffeine 12 , citrulline 16 , beta-alanine 4 , and creatine 8 can help maximize your energy and strength while reducing fatigue.

Make sure key ingredients are present in research-backed dosages. There are countless research studies that pinpoint the minimal dose needed to experience energy- or strength-boosting effects from ingredients like beta-alanine and creatine, but here are a few you should know before you start shopping:.

These blends will make it difficult to know the exact dosages used. A detailed ingredient list that clearly states the dose of each ingredient will ensure you know exactly what you are consuming.

This means that a company, not affiliated with the supplement manufacturer, evaluates the dietary supplement to ensure what is printed on the label is actually inside the product. RELATED: Best supplements for men. When taken as directed, pre-workouts are generally considered safe to use for healthy individuals.

The name pretty much gives it away—pre-workouts should be taken before your training session, with most people downing their supplement minutes before they intend to start seriously training.

That means if you down a pre-workout even at 1 p. Consider using one of the best stim-free pre-workouts or moving your workout to earlier in the day. With countless pre-workout supplements currently on the market suitable for just about every goal, the choices can seem overwhelming.

Having a strong pre-workout can be a great way to wake you up for an early morning lift or help you find the energy you need to crush it after a long day. Your ability to focus and be mentally in tune with your workout is crucial, and some pre-workouts, like Legion Pulse, claim that ingredients such as alpha-GPC may give you the focus you need.

This formula is flush with mg of alpha-GPC to potentially boost focus and mental sharpness. This ingredient may help balance out a massive dose of mg of total caffeine, so you can focus that energy and put it to good use.

Alpha-GPC may not receive all the hype that big-name ingredients like caffeine or citrulline do, but it may be a beneficial ingredient nonetheless. It may help to increase the production of acetylcholine in the brain, which can potentially improve motivation and focus.

Acetylcholine is also responsible for making muscle contractions happen so that it can lead to more power output , too. Gaining a mental edge over the competition can oftentimes make a huge difference. With the priority on focus and mental sharpness, this pre-workout can help you turn that jittery feeling you may have from other pre-workout formulas into laser-focused training energy.

Read our full Legion Pulse Pre-Workout Review. Creatine is probably the most common and well-known supplement for many lifters who are interested in becoming bigger and stronger. Kaged Pre-Kaged Elite contains two different types of creatine — 3,mg of monohydrate and 2,mg of nitrate — to equal a full dose of 5,mg in total.

While creatine monohydrate is by far the most well-researched and easily available type of creatine on the market, there is research that suggests creatine nitrate may improve its bioavailability for the body and muscles.

Aside from providing a generous helping of creatine, Pre-Kaged Elite also has a bunch of other power players in it, like a massive dose of 10,mg of citrulline, 3,mg of beta-alanine, and a solid 2,mg dose of betaine to potentially aid in blood flow and pump.

If your current supplement stack is becoming a bit too busy or daunting, you may want to add a pre-workout and creatine combo that allows you to take one less supplement per day.

Kaged Pre-Kaged Elite provides pre-workout workhorses, like citrulline and betaine, while also including two types of creatine to equal 5,mg total. This product packs quite a punch and leaves the artificial stuff in the dust.

As most people have come to expect from Transparent Labs, this formula has all the right stuff in the right doses and is clearly labeled. If you prefer to keep your supplements clean while still ingesting a strong kick, then this formula is right up your alley.

Heavy doses of 8,mg of citrulline malate, 4,mg of beta-alanine, and over mg of caffeine headline the party of over 17 total grams of clinically-dosed ingredients. The scoop size is also more manageable than many other strong pre-workouts at 21g per scoop compared to some that are over 30g.

This helps the solubility, as our tester noted that it mixes easily without any residue or floaties. You can have your pre-workout and keep it clean too with Transparent Labs BULK Black.

This potent yet balanced formula is a great middle ground in the strong pre-workout space that helps you bring the noise while still hearing your own thoughts. Overall, though, they enjoyed the flavor. Not only does Legion Pulse sport some excellent flavors, but it also contains a potent blend of active ingredients.

Supplements are only helpful if you actually take them. Though some people may find the sensation off-putting or downright uncomfortable, there are some gymgoers who love the skin tingling feeling of a big dose of beta-alanine kicking in. If you count yourself among the latter, then Transparent Labs BULK Black is worth checking out.

Beta-alanine is most commonly known for its potential to improve muscular endurance. The sensation itself is harmless, though some find it pleasurable while others may find it uncomfortable.

Get ready for the feel of bees buzzing on your skin, folks. In addition to the hearty dose of beta-alanine, this product is a well-rounded and properly dosed pre-workout overall.

Despite the large doses, the serving size is smaller than many other similarly potent pre-workouts at 21g per serving, making this a bit more palatable too. A heavy dose of 4,mg of beta-alanine coupled with all of the other ingredients in this robust formula makes for a great pre-workout overall, tingles included.

Strong pre-workouts provide many of the same potential benefits that regular pre-workouts provide, only more so because of the increased potency of the formulas used. They offer more energy, higher doses of ingredients, and often an improved value over run-of-the-mill pre-workouts.

Here are some pre-workout side effects and benefits you can expect. If regular pre-workouts provide a jolt of energy , then the strongest pre-workouts can be compared to tapping into the power grid itself with their higher caffeine and stimulant content.

Generally, pre-workouts contain mg to mg of caffeine per serving, which is about equal to one or two cups of coffee. The strongest pre-workouts like those on this list contain mg to mg on average. Some are even higher than that for a massive dose of stimulants to potentially provide the most energy possible.

For those who are caffeine sensitive, though, there are plenty of pre-workout alternatives you can try. Along the same lines as the caffeine content, strong pre-workouts tend to contain higher doses of other popular ingredients, which can make them potentially more effective.

The downside of this is that the scoops and serving sizes are larger — with some being the size of a scoop of protein powder — which some folks might not like. Pre-workouts vary in price for various reasons, such as the ingredients, dosing of those ingredients, and sometimes the brand name.

A container can look expensive up front but provide a ton of servings, making it more cost-effective than a cheaper priced tub with fewer servings. There are a ton of ingredients that companies put in their pre-workout products with claims to boost mental focus, energy, endurance, and blood flow.

Alpha glycerophosphocholine, also known as alpha-GPC, is a precursor to acetylcholine, which is a neurotransmitter involved in memory, attention, and most importantly here — muscle contraction. Taking between mg and mg of alpha-GPC can have nootropic effects, such as cognitive enhancement and improved focus, as well as potential improvements in muscle power output.

Beta-alanine is linked to improved endurance, both in cardio-focused workouts and strength training with higher reps. The standard dose is 1,mg to 3,mg, though the pre-workouts on this list can have upwards of 4,mg.

This ingredient is commonly found in red beets and is the main ingredient in beetroot extract — though it can also be found in lesser amounts in leafy greens.

Caffeine is usually the main stimulant and has well-established potential ergonomic effects, such as better endurance, lower perceived exertion, improved power output, and even enhanced cognition.

Creatine is likely the most thoroughly researched ergogenic aid aside from caffeine. It can help power output, anaerobic capacity, fatigue, and even improve cognition all while increasing muscle size by potentially drawing more water into your muscles depending on the type of creatine you use.

The dose is generally five grams per day of creatine monohydrate — though different forms, like creatine hcl, have smaller effective dose sizes.

Research suggests, the effective dose of citrulline is around 5,mg to help potentially improve blood flow, performance in endurance, and power output. The pre-workouts on this list generally have higher dosing than that — even up to double for products with an emphasis on pump and blood flow.

These sorts of products can make some folks a little concerned about side effects and unintended consequences. Caffeine is a real drug, and thus, can have some real side effects if you take too much of it. Are you interested in a detailed guide on how to shop for pre-workout supplements like a pro?

Support your workouts and wellness in tandem. What should I consider when choosing a pre-workout supplement?

When choosing a pre-workout supplement, consider your fitness goals, any dietary restrictions, ingredient transparency, the presence of any banned substances, and potential side effects. Also, look for supplements with evidence-based ingredients like caffeine, beta-alanine, and creatine that are dosed appropriately.

How do I know if a pre-workout is safe to use? To ensure a pre-workout is safe, check for third-party testing by organizations like Informed-Choice or NSF. Read reviews, consult with healthcare professionals, particularly if you have pre-existing conditions, and thoroughly research the ingredients for any red flags regarding safety or side effects.

Can pre-workout supplements boost my performance? Yes, pre-workout supplements can boost performance. Ingredients like caffeine can increase alertness and energy, while others like beta-alanine may improve endurance. However, effects can vary between individuals and depend on the quality and dosage of the ingredients.

What are the potential side effects of pre-workout supplements? Potential side effects include jitters, insomnia, increased heart rate, high blood pressure, digestive issues, and headaches. These effects are often related to stimulant content, particularly caffeine, so monitoring your tolerance and starting with low doses is recommended.

How should I take pre-workout supplements for optimal results? For optimal results, take pre-workout supplements minutes before exercising. Follow the recommended dosage on the label, start with a half dose to assess tolerance, and do not consume with other stimulants. Stay hydrated, and be mindful of the timing, especially in the evening, to avoid affecting sleep quality.

This potent yet balanced formula is a great middle ground in the strong pre-workout space that helps you bring the noise while still hearing your own thoughts. Overall, though, they enjoyed the flavor.

Not only does Legion Pulse sport some excellent flavors, but it also contains a potent blend of active ingredients. Supplements are only helpful if you actually take them.

Though some people may find the sensation off-putting or downright uncomfortable, there are some gymgoers who love the skin tingling feeling of a big dose of beta-alanine kicking in. If you count yourself among the latter, then Transparent Labs BULK Black is worth checking out.

Beta-alanine is most commonly known for its potential to improve muscular endurance. The sensation itself is harmless, though some find it pleasurable while others may find it uncomfortable. Get ready for the feel of bees buzzing on your skin, folks. In addition to the hearty dose of beta-alanine, this product is a well-rounded and properly dosed pre-workout overall.

Despite the large doses, the serving size is smaller than many other similarly potent pre-workouts at 21g per serving, making this a bit more palatable too. A heavy dose of 4,mg of beta-alanine coupled with all of the other ingredients in this robust formula makes for a great pre-workout overall, tingles included.

Strong pre-workouts provide many of the same potential benefits that regular pre-workouts provide, only more so because of the increased potency of the formulas used.

They offer more energy, higher doses of ingredients, and often an improved value over run-of-the-mill pre-workouts. Here are some pre-workout side effects and benefits you can expect.

If regular pre-workouts provide a jolt of energy , then the strongest pre-workouts can be compared to tapping into the power grid itself with their higher caffeine and stimulant content.

Generally, pre-workouts contain mg to mg of caffeine per serving, which is about equal to one or two cups of coffee. The strongest pre-workouts like those on this list contain mg to mg on average. Some are even higher than that for a massive dose of stimulants to potentially provide the most energy possible.

For those who are caffeine sensitive, though, there are plenty of pre-workout alternatives you can try. Along the same lines as the caffeine content, strong pre-workouts tend to contain higher doses of other popular ingredients, which can make them potentially more effective.

The downside of this is that the scoops and serving sizes are larger — with some being the size of a scoop of protein powder — which some folks might not like.

Pre-workouts vary in price for various reasons, such as the ingredients, dosing of those ingredients, and sometimes the brand name. A container can look expensive up front but provide a ton of servings, making it more cost-effective than a cheaper priced tub with fewer servings.

There are a ton of ingredients that companies put in their pre-workout products with claims to boost mental focus, energy, endurance, and blood flow.

Alpha glycerophosphocholine, also known as alpha-GPC, is a precursor to acetylcholine, which is a neurotransmitter involved in memory, attention, and most importantly here — muscle contraction.

Taking between mg and mg of alpha-GPC can have nootropic effects, such as cognitive enhancement and improved focus, as well as potential improvements in muscle power output.

Beta-alanine is linked to improved endurance, both in cardio-focused workouts and strength training with higher reps. The standard dose is 1,mg to 3,mg, though the pre-workouts on this list can have upwards of 4,mg.

This ingredient is commonly found in red beets and is the main ingredient in beetroot extract — though it can also be found in lesser amounts in leafy greens. Caffeine is usually the main stimulant and has well-established potential ergonomic effects, such as better endurance, lower perceived exertion, improved power output, and even enhanced cognition.

The dose is generally five grams per day of creatine monohydrate — though different forms, like creatine hcl, have smaller effective dose sizes. Research suggests, the effective dose of citrulline is around 5,mg to help potentially improve blood flow, performance in endurance, and power output.

The pre-workouts on this list generally have higher dosing than that — even up to double for products with an emphasis on pump and blood flow.

These sorts of products can make some folks a little concerned about side effects and unintended consequences. Caffeine is a real drug, and thus, can have some real side effects if you take too much of it. It can cause anxiety, diarrhea, and maybe even temporary high blood pressure in mild cases of ingesting too much with more severe consequences coming from upwards of 1,mg over a short time.

Rather, everyone has a different tolerance for caffeine. Caffeine can make it harder for you to relax or disturb sleep patterns if taken close to bedtime. Keep in mind all the sources of caffeine you have throughout the day. One of which is beta-alanine whose minimum effective dose is somewhere between 1,mg and 2,mg.

This can cause a harmless yet somewhat uncomfortable sensation of skin tingling called paresthesia. Another ingredient to look for is citrulline — a common ingredient in nitric oxide supplements — which has been shown to be effective at improving blood flow during exercise with as little as 3,mg, though doses of 5,mg to 8,mg are more often recommended.

It can be quite easy to accidentally double up on an ingredient without knowing it and experience some potentially negative side effects. If the products are spread out compared to all at the same time, then it might be okay to have a bit over the normal amount of certain ingredients.

Just like most supplements, it depends on the person. You may have to throw on your lab coat and experiment for yourself. Most supplement companies that make strong pre-workouts like the ones on this list recommend starting with a half a scoop to assess your tolerance.

The more you know, the better informed you will be about the potential effects and how the formula works for you. This is especially key with potent doses like the ones on this list. Pre-workouts can be a great way to get that extra kick you need to make your way to the fitness center or focus up in a crowded gym.

These stronger-than-average formulas are more potent, and thus, can potentially elicit greater effects than more basic pre-workouts. That said, these are for experienced lifters who have been taking supplements for years and need the extra boost to gain an edge, or simply for it to be effective anymore.

That said, these supplements are generally considered safe when used as directed for those who are in good health with no pre-existing conditions. We like Transparent Labs BULK Black for its high doses of nearly all the ingredients that people are looking for in a pre. It also has a well-balanced profile and is reasonably priced, which makes it a great choice for a strong pre-workout.

These more potent pre-workouts are for those who have been taking regular pre-workouts for a while and have built up a tolerance to the ingredients, no longer experiencing the same potential effects as they used to.

Keep in mind that caffeine has a half-life of around five hours in healthy individuals. This is because it can potentially enhance the effects of caffeine, which can cancel out the possible relaxation effects theanine normally has.

The Support Blend is the third category and contains red clover extract, luteolin, and resveratrol. These ingredients can support mood when consumed in an adequate dose.

While this product contains ingredients with a decent amount of evidence to suggest they could positively affect your workout, the use of proprietary blends makes it difficult to know how effective the doses are.

Certified personal trainer and former competitive triathlete Amanda Capritto used Endura-Formance when training for her races and says it always gave her a boost, giving it a 5 out of 5 for effects.

Stimulants to keep an eye out for: High levels of caffeine, dendrobium, synephrine, DMAE, rauwolfia vomitora. This is subjective, but we base it on the views of our testers, as well as what the general consensus is in online customer reviews.

We took the individual flavor and full range of flavors into consideration. How well does this product dissolve in the suggested amount of liquid? Are there floaties? Is it grainy?
