I purchased this product to enhance my physique. Specifically, the nethers. I applied it just as it said on the label, "rub judiciously to area desired to enlarge". and I waited. And waited. And waited. The best effect I received was a warm glowing that my girlfriend found unnerving, though illuminating. Overall, this product did not work as well as the pumps or pills that I buy from spam emails. Would not buy this product again unless my Geiger counter needs to be calibrated. which it never does. because i don't own one.
