Anonymous It works great with a penis pump saw results on 1st try . i bought size-Rx and Mr.thick. Out of all three penis creams this one did or showed the most results after one use. very impressed of course, i used it with a penis pump. but i was not disappointed. though fair warning, the only thing i will say there is a cool burning sensation at first but if you can get through it. i promise you be impressed too.
