Because M is an anti-estrogen, does that mean that it will help reduce acne? or could it actually cause more? im wondering because im hoping to do the stack which tim described in BTS (the M and tribex stack), but im a little worried about any possible side effects. can any of the biotest guys answer this one for me? thanks

If anything it could cause an increase in acne but probably is not something you really need to worry about.

What is M?
