Creatine has been around for decades and it's one of the safest supplement, but results vary.
Did you try it? Did you benefit from it?

My recent experience is that I quickly gained some weight because the muscles swelled a bit (water retention) and it helped me recover quicker, which is helpful with a leg destroying series like #26 of Chiseled. I lose the water weight when I go off it and keep the muscles .

The key to creatine is to drink tons of water. I used to take it alot when I wanted to lift alot of weight. I used it to reach a goal of benching 300 lbs, once I accomplished that I stopped using it and lost like 5 lbs, but the strength was still there. Your body produces creatine to help muscle development, you are just adding to the amount of creatine in your body.
