Are these supplements any good? Dangerous? I know they are not technically steroids but natural anabolic stimulators... just the thought of messing my body's natural PCT up by pumping more testerone derived compounds/supplements into it makes me hesitant.. The reviews seem really good though and people are noticing better gains. This guy at the gym told me to try Extreme Tren but said he competes for some sport and isn't allowed to take it.. hmm.
