If there was a way to make your penis bigger, it wouldn't be a secret.. it wouldn't be a "does that actually work" and it would be the lead story on Good Morning America.. think of what happened when Viagra was released... it worked and every single person in the world knew about it.

those dick excercize machines are not only pointless and useless, they could conceivably injure your customers.

Permamant Penis enlargments are the Big Foot of the porn world... there's lot of fuzzy evidence that they would work, just no REAL evidence that wasn't faked.

Would I sell them on my site?

No.. because if such a pill worked, people would be at their doctors banging down the door for a prescription. Drugs that actually work don't need to be sold on the internet.
