Some bodybuilders and athletes use trenbolone esters for their muscle-building and otherwise performance-enhancing effects.  Such use is illegal in the United States and many other countries. The DEA classifies trenbolone and its esters as Schedule III controlled substances 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 allegedly administered to Russian athletes at the Sochi Winter Olympics consisted of oxandrolone , a metenolone ester, and a trenbolone ester. 
Hey, great list!
I don’t use them personally, but I train with a few women who do. I’ve noticed some of the side effects and they’ve mentioned it too.
But I didn’t know what to look for and how many alternatives there were – so while I’ll probably still choose not to use any (my goals are just to stay active), I’ll pass this along to my friends who want different results than I do. Maybe it’ll help them make some good choices, or to switch to something with fewer (or no) side effects.
The truth is simple; there is no steroid like Trenbolone and while it may carry some potential adverse effects many men will supplement with no problem at all. You will find no steroid to pack such a punch on its own; in-fact, there are very few combinations and stacks that can be as potent as the Trenbolone hormone is on its own. For bulking and cutting this steroid has no equal and when combined with testosterone as it should be, if for no other reason than your health it is a hormone that cannot be beat safely making Trenbolonethe greatest anabolic androgenic steroid of all time.
