I started taking creatine to put on mass, and it is one of the best supplements on the market today. It is highly researched, very cheap, and highly effective. Allmax makes some good products, and this is no exception. I love that this creatine is unflavored because I can put it in my regular protein shakes. It has patented Creapure in it, so there is no chance of getting ripped off. Great product.
