hey, im 15, gone through puberty, been there, done that, and i play football. i've been lifting for a few months now and have gained 15 pounds of muscle and lost a lot of fat, but I'm still pretty small for my league. I'm 5'6'', 125 lbs. The biggest guy on the team is 6'4'', 225lbs, and the guys i want to overpower are about 160lbs. I'm looking to be about 140lbs, while retaining my cut body, so I'm wondering, is creatine for me?
