PHGH is a male enhancement pill developed and sold by adult-film star John Lawrence. The pill has been featured in Men’s Health and Ask Men and is touted as “the most effective and highest-quality product on the market.” [1]

I stripped PHGH down to its ingredients, the amounts used, and if they’re effective. I’ll share what I found.

The Claim

Lawrence’s claim is his product uses natural ingredients to increase blood flow, resulting in the hardest possible erection. Unlike other male enhancement manufacturers, Lawrence doesn’t say the product will just increase penis size and girth, but that each man will reach his full capacity with maximum blood flow, hardness and size.

He states, “PHGH was designed to do only one thing: maximize blood flow. Because that’s what makes our erections harder.” [2]

The Ingredients

PHGH uses a proprietary blend, which usually means the ingredient amounts aren’t listed. Surprisingly, the dosages of all eleven ingredients in the blend are available.

This is promising because it shows the company isn’t trying to hide behind a “special formula.”

Arginine is the first and most abundant ingredient; PHGH contains almost as much arginine as the other 10 ingredients combined. While most male enhancements, including Viagra, use PDE-5 inhibitors, PHGH’s main ingredient is arginine.

Studies have shown arginine increases nitric oxide production and relaxes smooth muscle fibers. The result is more blood flow and muscle relaxation to areas controlled smooth muscle, such as the penis. [3] [4] Basically, arginine pushes more blood into the penis for a harder, larger erection.

Subjects with mild erectile dysfunction in another study experienced improved erection hardness with 750 mg arginine daily. [5] PHGH provides 500 mg arginine in two capsules, so users should experience increased erection hardness.

Tribulus terrestris is a popular ingredient in many testosterone boosters, which is probably why it’s the second most plentiful ingredient in PHGH, at 200 mg per dose. While increased testosterone leads to greater libido, research is divided on tribulus terrestris’ effects.

Tribulus terrestris been shown to be effective for increasing erections in rabbits, rats, and primates, but it may not be as effective in humans. Other research indicates there may be a greater effect in older men with lower testosterone levels than in younger males. [6] [7] [8]

The tribulus terrestris amount in PHGH is more than that used in studies that reported positive results. The ingredient works for some men, and PHGH contains enough to be effective in those cases.

Lawrence calls tongkat ali (eurycoma longifolia) “an ancient and mysterious root that grows in the jungles of Indonesia … One of the most potent elements in any male enhancement.” [1]

Tongkat ali, Also called Malaysian ginseng, is a medicinal plant traditionally used as an aphrodisiac. Resent research supports the traditional use as a libido and testosterone booster and shows the plant is also effective at lowering stress levels. [9] [10] [11]

PHGH contains 100 mg tongkat ali per dose, significantly less than the 400 mg used in effective studies. This doesn’t mean the ingredient is ineffective, but the results may be less significant than those reached in clinical research.

L-Carnitine has effects similar to those of arginine. Studies examining L-carnitine found it is effective at treating erectile dysfunction when used with other ingredients such and L-arginine. [12]

Catuaba bark comes from a tree native to Brazil and is supposedly used by native tribes as a male enhancement: “Catuaba” means “what gives strength to the Indian. Unfortunately, I was unable to find any evidence that it is effective for penile enhancement.

Epimedium (horny goat weed) is effective because it contains icariin, which is a mild PDE-5 inhibitor. Studies show it effectively increases blood flow to the penis and may slightly raise testosterone levels and libido. [13]

PHGH has 20 mg epimedium, more than most effective studies use.

Gingko Biloba and Maca and DHEA are less prevalent ingredients in PHGH, but several studies have been published showing their effectiveness in treating erectile dysfunction and stress levels. The effects may be diminished because of PHGH’s small doses, but the benefits are legitimate. [15]

Muira Puama is another Amazonian plant. While some individuals claim it is useful for treating sexual disorders, I was unable to find any solid evidence of its effects. [16]

Piperina (Bioperine) is responsible for the potency of black pepper. Used in supplements, it increases the effects of the other ingredients. [17]

Price and Availability

Each 60-count bottle of PHGH contains 30 days of servings. One bottle is available from $39.95, two bottles for $67, and three bottles for $89. In addition, the company offers a 60-day money-back guarantee. [18]

The Verdict

Taking it down to just the ingredients, PHGH seems like a decent product. I really like that they provide the amounts in the proprietary blend; that’s not common and lends an air of legitimacy to their claims. The main ingredients are effective at increasing blood flow and testosterone and should enhance erection size, hardness, and length. However, some of the ingredients aren’t proven to be effective. They are included in very small amounts but are still there.

All in all, I like PHGH. The company is open about its ingredient amounts, and the price is comparable to other male enhancement supplements, with discounts for larger orders. The only thing I dislike is the non-proven ingredients.

Are there any side effects to this product? Thanks

October 16, 2013 at 12:28 am

Janson Davis Says:

Carol, PHGH has several ingredients that effect blood pressure. Also, here’s what WebMD has to say about Epimedium (one of PHGH’s ingredients): “Horny goat weed are POSSIBLY UNSAFE when used for a long period of time or in high doses. Long-term use of these other forms of horny goat weed might cause dizziness, vomiting, dry mouth, thirst, and nosebleed. Taking large amounts of horny goat weed might cause spasms and severe breathing problems.”

Owen F Silvious Says:

Oct 27, 2013. I used PHGH and id not cause my penis to get larger or thicker after erection. Maybe it does work on some males, but I have tried other male enhancer’s and none of them have made my penis larger or thicker after erection. It is a money making business for some people. I don’t believe any of the male enhancers work. Most all of them have the same ingredients.

Tim York Says:

Arginine is the most plentiful ingredient, but I’ve been told that it is hard for the body to convert Arginine into Nitric Acid and even more so for older people. L-Carnitine is supposed to be better for that according to some doctors. So perhaps the amounts of these two should be reversed. Has there been any studies that show people are getting more Nitric Oxide? There are simple saliva test strips to test for NO.

Is this something you take before having sex (30-90 minutes) or is it something you have to take everyday like a vitamin?

Doug Says:

I have tried all the male enhancement suppliments and have found that PHGH
works the best. Blood flow is definitely
better. Viagra works better but it has
bad side effects. Headaches-upset stomach-
blurred and colored vision. I definitely
recommend PHGH. No bullshit.

Danny Says:

I don’t know about anybody else, but I use it and it works amazingly well for me. I take 2 and 2 Zytenz, along with 1000 extra mgs of Arginine about an hour before. and I become unstoppable. My boyfriend will agree. Don’t pay attention to the directions, just take it right before you go out and look out! You’ll be the only top in a room full of bottoms!

The exact same ingredients are sold in numerous other similar products at about one third the price. The greedy scavengers are trying to sell PHGH (Puny Hard to Gain Hope) at 300% more than other similar products. Also beware that anything that you have to take every day is harmful, unnecessary and definitely a ripoff scam!
