I have a bottle of mdrol. i have ran two cyc in the past. the first was the ph trenv700 by b.d.l and i have ran some real gear of anadrol, trenboline, and winstrol. This will be my last cyc before i star to get tested for boxing. i know all the protocall i need to follow and the risk involved i have a very realible endocrinologist helping me too . My question(s) is how long will the mdrol stay in my system and how can i maximize my gains without having to lower my cardio.
