Some bodybuilders and athletes use trenbolone for its muscle-building and otherwise performance-enhancing effects. [ citation needed ] Such use is illegal in the United States and many other countries. The DEA classifies trenbolone as a Schedule III controlled substance under the Controlled Substances Act .  Trenbolone is classified as a Schedule 4 drug in Canada  and a class C drug with no penalty for personal use or possession in the United Kingdom .  Use or possession of steroids without a prescription is a crime in Australia .  The infamous "duchess" cocktail administered to Russian athletes at the Sochi Winter Olympics consisted of oxandrolone , metenolone , and trenbolone. 
The truth is simple; it may not be a steroid and it may not even be all that exciting but those who buy hCG are often massive fans of it as it serves its purpose extremely well. For those who run hCG while on cycle will they always fall prey to negative HPTA issues? Of course not but this peptide hormone is far easier to abuse than many realize and it's far safer to simply play it safe. In doing so you are only going to want to supplement with the peptide when it is most beneficial and as this is the PCT period it is the only period when we truly need to buy hCG. In the end those who buy hCG for their PCT needs will have a far more successful post cycle recovery; the transition will be smoother, they'll keep more of their gains and they'll simply be happier individuals and that's the bottom line.
How might this be of any importance? The beta monomer form found in ordinary HCG, but not in recombinant HCG, activates the TGF-beta receptor. I don’t think this activity provides an important risk for bodybuilding use. Women, for example, experience it for 9 months on end in some cases for multiple pregnancies and do not necessarily suffer much from it, and there’s a very extensive track record of safe bodybuilding use. However, TGF-beta receptor stimulation by this HCG monomer has a potential to promote some cancers. (In contrast, intact HCG is protective.)
