If you already boughtthen I wouldn't go and buy another creatine. See how works for you. If you didn't care for it or your body didn't respond well then try another form. There are plenty of others to choose from. I would start with the basic monohydrate since it has been around for so long and proven effective. Also Creatine HCl has been proven to be effective as well. See what works best for you, which involves trying new products.
