Each serving of Creatine 6000 ES contains 5 grams of pure, HPLC-tested creatine monohydrate that is quickly and efficiently absorbed by the body and drawn into the muscles, where it's needed most.

In one 6-week study that included weight training, previously trained subjects using creatine monohydrate gained an average of nearly 6 pounds of lean mass, while previously trained subjects using a placebo gained an average of just 0.37 pounds of lean mass.
