I'm going to be honest with you Geoffke.
You're 19, you weigh 170 lbs (previous post), your nutrition knowledge is mediocre at best (previous post), I'm betting your training knowledge is on par with your nutrition knowledge (just a guess), and once again, you're 19. Have you put on forty pounds of muscle since you started training? If your answer is no, and all of the above statements are true, then you should not even be dreaming about juicing for another couple years. Remember, if the diet isn't there, you're screwed. If the diet AND the training aren't there, you're hopeless. This is definitely NOT a flame, no offense intended. I wish you luck.
