Penis enlargement pills or the so called “natural male enhancement pills“, should not be taken from people under 18 years old, unless discussed with the medical doctor first.
These products do not directly increase the penis size. At first place they will increase your sexual energy, sexual recovery, and the intensity of orgasm, which will lead to more blood flow to your penis. This will lead to it’s growing, just like the muscle is growing when bodybuilders train.
Some of the active ingredient that these pills contain Ginkgo Biloba, Saw Palmetto, and other natural herbs. They increase blood flow and are used for curing erectile dysfunction.
Another active and well known and used ingredient likely to be in it would be Ginseng. It’s been reported to increase sexual stamina.
On some penis enlargement pills there will be disclaimer telling not to be taken unless your 18 years old. However they will say also that if you have current medical condition it’s generally safe.
