I agree to wait till your alittle older, only for information reasons. I wish i knew then what i know now about juice when i first juiced. I was 18 years old 5'9'' 140 pounds, ate like crazy trained hard for 9 months solid and gained i think 4 pounds, straingth went up, i just couldn't gain weight for the life of me. So i turned to AS, ever since my first cycle, even naturally weight is not a problem, although naturally isn't half as fun =o) Just wait it out bro, let you body get alittle older, learn as much as you can possibly learn... research... research.. research..
