I've been using this product known as M5 extreme for sometime now, its a Kre-alklyn based product, but I recently heard that and estrafied form of creatine such as BSM'S CELL MASS was far more effective and cheaper. Comments?????
I have never used it personally, but BSN makes decent products for the most part. I would say if it fits what you are looking for, then go for it. Let us know.
