Cutting Gel definately doesn't work as claimed. The ingredients act as a diuretic instead of a true fat burner, and there haven't been any signifigant studies to prove that spot reduction via diuretics actually works. On the other hand there is lipoderm-y from avantlabs which sounds very promising. It'll definately work as a potent fat burner and there is signifigant scientific literature to back up claims of using it for spot reduction.
I don't trust those products. You never know what that stuff could really do to you. The commercial says it puts the fat into your blood stream, correct me if i'm wrong, but that doesn't sound too healthy!
