I've been using S.A.N. lipoburn (contains aminophylline, yohimbe HCL, usnic acid, and forskohlli/$29.95 for a 2 oz. jar) for the past 4 days, and I'm still waiting to see results. Has anyone had any success with this product? In theory, the ingredients are probably as good as one will find for fat loss products, but I'm curious whether this, or any other topical application will truly work.
