Pills for penis enlargement? You must be joking. The whole penis pill industry is based on the assumption that a large number of men will give them a try, at least once.

For this reason, a selection of largely useless ingredients is lumped together, given an illustrious name, and sold at a high price.

No repeat customers anyway, because all these pills do nothing for penis size.

Of course there is Viagra. It causes an increase in penis size by facilitating erections. But Viagra will make an erection only as big as it would occur through sufficient stimulation anyway, provided there is normal functionality.

But that's not what the buyers of penis pills have in mind. They want a larger erect and flaccid penis, not just facilitate the erectile reflex.

No pill will achieve this.

On the other hand, there are numerous medications that can cause penile shrinkage, temporary as well as permanent.

Temporary shrinkage is caused by amphetamine, metamphetamine, and even cocaine. Semi-permanent or permanent shrinkage is caused by any medication that inhibits the body's own testosterone production, and this means: by steroids (synthetic testosterone), natural supplemented testosterone, and some andro… testosterone precursors. So, while there is nothing one could take in the form of pills to increase penis size, there are plenty of pills to decrease it.
