I've actually seen this question posted more than a few times. I'm guessing the "logic" behind the question is that, Creatine is a cell volumizer that helps pull water into the tissues. The part they leave out is that it is a SKELETAL MUSCLE CELL volumizer. The penis has very little muscle tissue in it....and, the little bit there is...is SMOOTH muscle, not skeletal. No, Creatine will not help make your penis bigger. It's great stuff for quick boosts of strength and a good pump in your other muscles though....I have some past experience with it from when I worked out more regularly/vigorously.
