Creatine Use in Weight Lifting

[Chaerophon]

That is something that I read but have not actually seen.  My friend across the hall, Peter, went from 6'1 165 pounds his sophomore year of highschool, to 6'1 215 pounds in just under 3 years.

That's a tough span of years to use as an evaluator of creatine's effectiveness. Guys tend to fill out during that 17-21 period. Perhaps some of that was due to this effect? What Ajax said strikes me as true; Creatine only provides water bulk during the cycle. After it's over, the bulk goes with it. I can say that from experience. Maybe your friend was on a heavy weight gain / protein diet as well? That could explain it. The only other explanation that I can think of is steroids. I wouldn't want to assume that without knowing your friend a bit better. However, gaining nearly a third of your original body weight in pure muscle mass in less than three years tends to strike me as a little bit suspicious. Then again, maybe he just worked really hard.
