To make penis bigger

Other than treatments for ED, or micropenis, no.

Be aware that the supplements industry paid off enough congressmen that the law was changed so that supplements are totally unregulated. They do not have to pass any FDA test for safety or efficacy. Nor are there any inspections of their facilities, or testing of dosage.
They can claim anything they want, even if they know it is not true, to get your money, and nothing stops them.

Besides, if something DID work, it would be big news….

So save your money.

Male “enhancement” is the slimy salesman’s way of protecting himself from a faulty advertising lawsuit. Those people selling products like Enzyte or Extenze can’t legally say “penis enlarger” because they know that it can’t enlarge the penis at all, in fact, you’ll notice that commercials for such products never even say penis. Those products are placebos, things that don’t work but you believe work and so trick yourself into seeing results. There is no way whatsoever to increase penis size short of surgery, any other way is false or dangerous, including, but not limited to, pumps, exercises, and other such crock. Viagra and similar medications give you erections, to cure ED, they don’t alter size at all, and taking them without ED can lead to bigger problems. Just be content with what you have, your confidence in your body is a lot more appealing than a large penis.
