Viagra, Levitra, and Cialis work in helping some men achieve an erection that they normally could not without help. That is why these drugs are manufactured by vebillion dollar drug companies that spend many millions advertising their products.
If
any of the penis enlargement pills, creams, (now oils?) actually worked, you would see Super Bowl commercials by the major drug companies. Instead you see the fakers sending out billions of SPAM emails and pop-up ads, etc.
