Some health risks of anabolic steroids include:. Because of this, they have never been tested or approved by the Food and Drug Administration FDA and could pose serious health risks to athletes. The full, long-term side effects of anabolic steroids many include other issues that are not on this or any list.

Additionally, it is illegal to use anabolic steroids without a prescription and oversight from a healthcare provider. In addition to anabolic steroids such as DHEA and so-called designer drugs, other dangerous or illegal ergogenic aids include:. The above ergogenic aids are potentially harmful, banned in Olympic competitions, and often illegal when used without a prescription.

However, diuretics are an exception to the rule in that people can sometimes use them safely and without supervision from a professional. Some diuretics, like acetazolamide, are used by athletes to mask the presence of other banned substances.

However, caffeine from other diuretics like coffee or tea is safe for moderate use in conjunction with balanced nutrition. For more information on banned and dangerous performance-enhancing substances, check out the National Collegiate Athletic Association NCAA list of banned substances.

Many performance-enhancing supplements offer safe options for improving athletic performance. Branched-chain amino acids , or BCAAs, include leucine, isoleucine, and valine. These three essential amino acids have a unique, branched chemical structure that allows the mitochondria in skeletal muscle tissue to metabolize them.

BCAAs can provide energy during exercise when metabolized, possibly providing greater strength and muscle mass gains from training. With no reported adverse effects for doses of up to 20 grams per day for up to six weeks, BCAAs fall under the category of safe and legal performance-enhancing supplements.

In addition, Ingredient Optimized options such as ioBCAA offer increased bioavailability of each of the three essential amino acids to ensure you receive the best possible benefits. Protein is one of the most common performance-enhancing supplements among athletes and non-athletes alike.

Protein assists with building, maintaining, and repairing muscle tissue, and it has been proven effective in numerous clinical trials. A quality protein supplement can optimize muscle training response during and after exercise.

There are no adverse effects or safety concerns reported at daily recommended intakes for athletes of up to 2 grams of protein per kilogram of body weight one kilogram equals 2. These products have been scientifically proven to offer better bioavailability than non-optimized protein supplements, ensuring you see results and are not wasting your money.

Creatine is a widely-used, thoroughly studied dietary supplement for sports performance. It can help supply energy to your muscles for short-term, anaerobic activities, such as HIIT, weight training, and circuit training. Aside from supplementation, creatine is obtained in small amounts from food and produced by your body.

Creatine supplementation may help you increase power and strength from full effort muscle contractions. It can also help your body adapt to athlete training regimens over time. It should be noted, however, that creatine does significantly enhance performance in endurance activities.

Typical doses of up to 20 grams per day for up to seven days or grams for up to 12 weeks show minimal safety concerns. Adverse effects are most likely to include weight gain caused by water retention, not fat accumulation , muscle cramps, muscle stiffness, and nausea.

Creatine monohydrate is the most widely used and well-researched form of creatine, but it also comes in creatine anhydrous, which contains more creatine by weight. Both options offer the benefits of creatine supplementation.

Caffeine is one of the most widely used substances in the world. Some claim that wild yams Dioscorea villosa can enhance performance due to its anabolic properties. Wild yams contain a substance called diosgenin, which can be converted to DHEA in a laboratory setting. The human body is not capable of converting diosgenin to DHEA.

Yams offer no performance-enhancing benefits, but there appears to be little risk of side effects. Gamma-oryzanol, also known as rice bran oil, is derived from sterol and ferulic acid.

It has been marketed as a way to raise serum levels of testosterone, but has no proven anabolic effect. Some claim that tribulus terrestris puncture vine can increase testosterone levels by stimulating the pituitary gland. Smilax comes from desert plants containing sarsaparilla and contains the building blocks for artificial production of anabolic steroids.

Saponins are building blocks for the laboratory production of steroids; however, the body is unable to convert smilax into testosterone or any other steroid. Yohimbine is extracted from either yohimbe bark or the South American herb quebracho.

Some claim it increases blood flow through the testes, leading to higher testosterone levels. There is no proof that yohimbine has any anabolic effects, but it can be extremely dangerous. Combining yohimbine and tyramine found in many foods and wines can cause an acute spike in blood pressure.

In addition to hypertension, side effects of yohimbine include seizures, paralysis and death. The club drug GHB is a CNS depressant made by combining degreaser or floor solvent with drain cleaner. For some reason, a number of uninformed bodybuilders became convinced that they could build muscle mass while they slept by taking GHB.

Some extremely uninformed bodybuilders took GHB around the clock, risking an overdose. A GHB overdose, as well as unsupervised withdrawal, can be fatal.

Not surprisingly, there is absolutely no research to support the idea that GHB enhances muscle mass in anyone, awake or not. Diuretics are sometimes used to hide traces of illegal or banned substances.

Competitive bodybuilders sometimes take diuretics before competition to shed excess weight and increase muscle definition. Taking diuretics, especially during increased physical activity, can lead to dehydration, syncope and heat-related emergencies. The use of most performance-enhancing drugs and supplements appears to be at best a waste of money, and at worst fatal.

For those considering a supplement, here are some tips for selecting wisely Some are ineffective and dangerous only to your pocketbook. Some, such as anabolic steroids, will work, but pose outrageous risks. Creatine is one of the few supplements that appears to have considerable research to support the claims made of it.

Thorough research, consultation with a physician and a healthy skepticism continue to be the best approach toward any drug or supplement. EMS professionals familiar with the facts are better equipped to discourage use of dangerous supplements and recognize patients who are potentially at risk.
