its not really too meaningful I think. he and the authors draw conclusions that don't make sense to me. For starters, there is no look at muscle mass or fat mass, which is a major consideration for us. second, look at the doses. 30mg/kg + 60mg/kg? for most of us, that translates to 3 or 6 GRAMS a day. Plus its injected rather than oral, which could make it even more potent.
Picture as well, how winny and other steroids react differently to oral vs IM administration. Winny oral lowers SHBG, IM doesn't. IM raises protein synthesis far more than oral.
