It is a steroid, or a pro hormone or whatever supp companies wanna call it. It is a androgen (male hormone). It is not natural to supp your body with hormones, but I will admit there are worse things you could be doing or adding to up body.
It is unlikely 1-ad will harm your liver, kidneys, whatever, but the possibility for a negative interaction with the drug is always a possibility. I have never touched any of the OTC juice but all my buddies have tried it and most are not impressed with any of it. Too many sides, not enough gains.
If you are interested in 1-ad you can find it anywhere; prices vary so shop around.
Var could be a midget, who the fuck cares.
