I have been taking thermolife's CRe2 for about 3 weeks now. Im just now starting to tell the product is working. Im keeping my pump longer in the day, and I dont know if this is from the product, but my veins look awesome as of recent. I have talked with lots of people about creatine ethyl ester, and it seems to me that the most popular is pureCee. I will probably try it when I run out of CRe2. I have found that my diet plays more of a factor than my supps. So as long as your diet is in check, I think the CRe2 or purcee will work great for you. good luck!
