Check out the VPX forums, they have a sticky for Hemogex feedback only.
If it makes any difference, I am currently on my 3rd week of Hemogex and have noticed slight fat loss effects and moderate pumps. The most noticeable thing is that hemogex gives you a great rest at night.. BTW, VPX has discontinued production of Hemogex until they expand their business (they are experiencing growing pains)
