Epistane-if it is legit-in my experience (numerous runs of each) is significantly better than tbol for bodybuilding purposes. Fullness, vascularity, hardness/graininess, strength, and just overall well being are some of the benefits I experienced while on it. It's definitely one of my favorite orals. The worst sides were insomnia and back pumps without taurine supplementation. Insane back pumps and just overall fullness. I've had blood work done countless times and it was never harsh on my liver, but I was also never reckless with it - I ran like 30-60 mg/day for the most part.
