Tweetyeah^ every 4th day is really the way to go. and yes you are young. younger then me if i remember? The only thingi regret about AAS was not waiting. if i would have spent the last few years reading and learning and waited till like now to juice i would be much happier. i wont sit here and try an convince you not to juice as if you want to you will and i know that from experiance. i will just tell you what my opinion is and help u out if i can so if you do decide to do it at least youd do it right lol. Your first cycle will be you best so its better to already be big you know?
