I'm down 3% bodyfat and haven't lost any actual weight. I suppose that's good because it really is maintaining muscle, but I think mentally it messes with me because I'm used to see loss of poundages with fat burners.
I have noticed more lines and muscle contour in my forearms, which for my body is usually a sign of leaning out and my waste has shrunk in overall diameter. However, even through I know better then to rely on the scale as a measure of progress, it's a habit hard to break, but I'll attest that Leviathan Re is really maintaining my muscle while cutting.
