good luck
forget about finding a simple answer. if you're really afraid of hair loss and/or acne (the mildest side-effects of roids) then forget it. we're not talking about popping vitamin-C. kidney/liver damage are the main concerns here. you have to make the decision whether or not to juice based on risk/benefit ratio.
all steroids carry the risk of hair loss/acne/kidney damage/liver damage/agression/depression/impotence/loss of sex drive just to mention a few side effects.
basically, the stronger the steroid the more side effects. this is not entirely true but it has a basic truthfulness. you could take oxandrolone if you're worried about hair loss, but forget about making the real big gains.
for a newbie who is serious, I'd take a close look at the Testosterone Enanthate/Cypionate @ 300-400mg/wk and accept the sides.
