Remember that this board reaches a worldwide membership. I can not vouch for pills adverised or marketed outside the United States. Somewhere else there may be something better or different.
Inside the U.S. all drugs and "supplements" are regulated under the most idiotic rule system imaginable by the F.D.A. If you try and read and or understand this crap as to what is and is not legal the only thing you'll get is a pounding headache.
But....Some general observations.
Of the pills I have so far encountered offered for sale inside the United States the ONLY contents are herbal or plant based ingredients.
Remember to actually achieve penis enlargement we are not talking anything other than cellular growth/division. Under F.D.A. guidelines anything that CAN cause cellular growth or division is not able to be classified as a supplement but instead would fall under the category of a drug. Plant based ingredients as a whole are NOT biologically active in human with only a few exceptions.
To create these "exceptions" very expensive chemical processes have to take place and to the best of my knowledge, no enlargement pill manufacaturers inside U.S. Borders are doing this. Also, the FDA now classifies anything "altered" in this manner as guess what "a drug", and we are now back at square one.
Again, something sold outside U.S. Bodrders may be very diffferent, but the best bottom line is that if it would work, the F.D.A. will not allow it to be marketed inside the United States.
Those of you residing in the U.K., Europe or other locations might do far better.
