Well I think some people are more suseptable to aas and hair loss than others. Some guys I know take it often without any hair loss products and don't lose a hair. I believe I'm somewhere in between the guys that can't lose their hair and guys who shed alot. Which is why I thought it may be worth the risk for this cycle. Also I've read it's supposed to be good for acne (whether its true or not). I just wanted to hear some varied opinions. I didn't know that it wouldn't protect me from the mast that is interesting but I'm not asking if I should change my cycle.
