I don't care what anyone says the science says. I've gone almost 45 days free from PMO, and before that I had a long streak as well. I've gained a considerable amount of muscle, I was 165 and now I'm 185 and not all of it is muscle but a lot is. I know that because my lifts at the gym have gone way up. I'm bench pressing over 200 lb, dead lifting over 350, that's a gigantic increase over what I used to do. And I used to have hardly any facial hair, just a few spots that formed a thin goatee but now getting hair growing in more thick all over my face. Many people say that no PMO can't increase your T levels and I don't know if mine have gone up but I do know that I feel fantastic and I'm much stronger and more muscular. Even my mom has noticed it and commented that I look more muscular. I had spent a couple years in the gym before and never had nearly the results I've had in the last few months.
