Winstrol does not convert into Estrogen and has no Estrogenic activity on its own right, and so the gains expected from Winstrol should be that of lean, hard, quality lean mass muscle gains with no water retention at all (provided other aromatizable anabolic steroids are kept under control with an aromatase inhibitor ). Totally bodyweight and strength gains are not known to be as dramatic as the stronger more aromatizable anabolic steroids such as Dianabol , but gains resulting from Winstrol should always leave a measure of satisfaction in the individual at the end of a cycle, provided nutrition and training are both properly set.
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 .
