intenstity of training is insane, imagine how often you have to stop squatting for example because you got to breath
also recorvery is much much faster
combine EPO with O2 mask for max results
EPO is not only for endurance athletes, ask worlds top sprinters
but very dangerous for the cronically overweighing bodybuilders and very expensive
ever realised that some 300lbs pro are doing a set of 500lbs squats and breath like no tomoro, while others finish a set and just start talking
