We put enough in our bodies, why do so w/ another chemical when this is very easily controlled through better attention to diet (macros). If we've learned anything on this board, one can certainly put on lbm (especially while on aas) while maintaining or even losing bf. Bulking??? No need... Adjust carbs, pro or fat, toggle calories around to see what works for you. No need for the clen bro. Get your diet in check and you can gain very efficiently w/ little to no bf gain.
