Guys you're not realizing fast metabolism will help you gain muscle in a more desirable way than slow metabolism. With fast metabolism you can eat like no other. I have fast metabolism and eat myself sick. But its the healthy stuff that counts. You wont gain mass like some people, but you've got the oppurtunity to be cut. With slow metabolism, you gain mass and weight, but then have to go back and do the cutting and refining...it all equals out over time.
