Are you wondering which common ingredients can be found in male enhancement pills? Good question! Generally, male enhancement pills contain natural/bio ingredients such as herbs or natural herb extracts, roots, botanic ingredients, and protein amino acids which are not harmful.
They all are classified as dietary supplements, have no side effects and do not fall under the scrutiny of the Food and Drug Administration for approval or disapproval.
However, the substances in the VigRx Plus pills and ProSolution pills listed below all appear on the Food and Drug Administration’s “generally recognized as safe” list.
Good Manufacturing Practices (GMP). Certified Pharmaceutical Facility.
Independent, third-party certification program which includes inspections of manufacturing facilities to determine whether National Nutritional Foods Association specified performance standards are being met. Standards specified and measured include staff training, cleanliness, equipment maintenance, record keeping and receiving of raw materials. ProSolution as well as VigRx Plus are allowed to use NNFA’s GMP seal on their products.
L-arginine (HCLI)
L-Arginine is a naturally occurring amino acid, one of the “Semi-essential” amino acids that can open up blood vessels throughout the body.
Semen Cuscutae/Cuscuta chinensis.
Cuscutae seed is used to treat impotence, premature ejaculation, frequent urination and sexual disinterest in males. Cuscuta is frequently used in long-term tonic programs, most commonly to strengthen the uro-genital functions, particularly premature ejaculation.
Cuscuta seed is also widely used to nourish the sperm and to strengthen the sinews of the sexual organs. It is used to increase fertility in both men and women, and is listed as an aphrodisiac in all traditional Chinese pharmacopoeias.
Gingko/Ginkgo Biloba.
Ginkgo has been known in Chinese herbal medicine since the last century. In the last 50 years Ginkgo effects and benefits have been clinically tested and proven. Ginkgo improves peripheral circulation, oxygenation, and increases the blood flow to the genitals to improve sexual function and the power of an erection.
In a recent scientific study, 69% of men with non-medically caused impotence problems reported significant improvement – significantly, with no side effects. It improves the arterial inflow to erectile tissues through arteries and veins without any change to systemic blood pressure.
Yin yang huo/Horny Goat (Herba Epimedii).
Research has shown that this herb helps to increase the male sperm count and semen density substantially. Herba Epimedii also expands the circulatory system’s blood vessels, while allowing hormone-enriched blood to penetrate sensitive tissues. It also frees up testosterone which increases one’s sex drive and endurance.
Hawthorn.
This is most definitely the best tonic for the heart and circulatory system. It has restorative and stimulating properties.
Fructus Crataegi (Hawthorn Berry).
Hawthorn berry is rich in bio flavonoids, which relax and dilate the arteries. These compounds are powerful antioxidants that help increase the flow of blood and oxygen to the heart. Bio flavonoids give strength to the walls of the blood vessels and improve blood flow to other areas of the body. Components in Hawthorn berry will lower the cholesterol level and the amount of plaque in the arteries.
Ginseng (Korean Red).
It improves the endocrine gland function and has a positive effect on the sex glands.
Catuaba/Erythroxylum catuaba.
The most remarkable quality of Catuaba lies in the area of treating functional impotence of the male genital organs. It works as a stimulant for the central nerve system. It is an innocent aphrodisiac, and is safe and highly effective for long term use. 
Ptychopetalum olacoides (Muira Pauma Bark Extract).
This ingredient is a powerful aphrodisiac used for improving one’s libido and treating erectile dysfunction. This extract is native to Brazil and has long been used as aphrodisiac and nerve stimulant in South American medicine. Ptychopetalum olacoides was used to restore sexual virility and to treat genital weaknesses.
Serenoa repens/Saw Palmetto.
Widely used for the promotion of prostate health. Historically, Native American Indians used the berries as a treatment for impotence.
Momordica.
Increase body testosterone levels. Source of Vitamin C and it contains proteins which show promise in promoting anti-HIV activity.
Zinc/Zinc Gluconate.
Zinc aids in increasing the sperm’s mobility and quality. As known, testosterone is the most effective anabolic our bodies naturally produce, and zinc plays a very important role in our testosterone metabolism.
Well, let’s say you are not satisfied with your penis size and decided to work on some enlargements. What is the first thing you should pay your attention to? The answer is – what is the penis size you have now! 
Not everything you read about penis enlarging pills is true. Your penis will never get larger if you rely on pills alone. Unfortunately, there is no “magic pill” that will make your penis bigger in a blink of an eye.
