Some athletes take normal testosterone instead, which has the same effect. Though testosterone is a natural hormone, illegal use of it can be detected. Examples: drostanolone, tetrahydrogestrinone (THG)
The positive effect of increased testosterone concentrations on athletic performance may be associated with improved physical performance and on several psycho-emotional factors, such as motivation, focus and dominance [6,7].

In this case, athletes must purchase creatine containing supplements on their own.
At this point, there is no evidence of widespread use of Viagra by elite athletes, Tygart said. Yet, because the drug is not prohibited and thus not screened with any routine urgency, there is no way to know precisely how popular it is.
In some cases, testosterone replacement therapy and illegal steroids have identical ingredients. What differentiates the treatments is the dosage used and the medical supervision involved in TRT.

It's kind of scary with some of these chemicals that are in some of these things, so you have to be careful."
