Creatine is sold in many forms, with two of the most popular being creatine HCL and creatine monohydrate. Although creatine HCL is effective at a slightly lower dose than creatine monohydrate, it’s more expensive. For this reason, people usually take creatine monohydrate as it is both cheap and extremely effective.
Don’t be fooled by fancy marketing and hype—creatine monohydrate is as good as it gets for increasing power, strength, and muscle mass.
