Billy boy, someone put up a post like this earlier, they had a link to a website showed that is was total junk. Personally I just got off Creatine, and I didn't like it. I used it in the past, and got strength, but this time, I guess cause I have toned down, made me look bloated. Made my muscles actually look bloated. course that is what it is supposed to do. Love the strength, but I found that I can get strength without using Creatine. I went to my doctor about some gyno concerns, she told me to get off the creatine, I did and it went away. The Creatine made my mild gyno more apparent. flushed the creatine out of my body and no more water, hince no more bloating. My muscles look fuller and learner, course like I said, I recently went on a cutting up cycle. I dont' suggest anyone use Creatine on a cuttin cycle, it just bloated me up, and made me look fat almost. Just my opinion and experiences and all. I have used the Creatine Serum, found it did give me energy, but didn't do much else for me. I personally think there are other suppliments out there, that will give you same gains as Creatine without the bloatyness.
