As far as anything you've seen on TV or the Internet that claims to "make you bigger," they are all scams.
However, prescription drugs like Viagra, Cialis, Levitra, and Alprostadil (Caverject) do indeed work to provide an erection but won't necessarily make you "larger." Your doctor most likely won't prescribe them unless you have "ED."
Neither do “weights” nor "stretching" devices work. In fact you can cause irreparable harm to yourself if you use these!

(Just saw that smc had already responded--I totally agree with his last recommendation! Also you want someone who accepts you for who YOU are. Not everyone is 9-12"--except on this forum!

Sorry couldn't help it!
