I'm not sure, but I'm on day 14 and down about 6 lbs with maybe 6 more to go - not sure. Actually eating more calories. I cant begin to tell you how much better my stomach already looks. My joints feel so much better and my muscles arent nearly as tight. All around feel better. I dont think I'll ever touch hgh again, I can see it's benefit in adding sheer mass but that's never been a goal of mine. I know it affects others differently but for me it seemed to push a ton of water in my muscles and right over my abs.
