Useful as lube, there was no plumping. Had some tingling which felt good. Did nothing for increase in size or erection.
Size RX Penis Plumping Male Enlargement Cream by Body Action
As another reviewer wrote, this medicated-smelling cream (it is NOT a regular lube) isn't going to bring about any radical changes (the ad copy here is way over the top). But as a product that might increase dilation at the surface it may be marginally more useful than straight lube and so it might be worth the extra expense (YMMV).
I would purchase it again.
SizeRX was great. Mr thick dick is nice glorified personal lube. Plump is likely about same as Mr Thick Dick. Haven't used Plump but once. More other stuff to try for u and Wish.
