Hi was just wondering if you guys could help me out. Are the natural test boosters from supplement stores like gnc and bodybuilding.com beneficial to take by themselves to increase gains or are they only used in post cycle therapy (pct). I guess what i am asking is it a waste of money to do them on there own. I have never done a cycle thiking about it real hard. Just wondering if a natural test booster alone would give me some more gains?
