Longinexx

longinexx

Longinexx is a male enhancement supplement formulated to improve blood flow to produce stronger erection quality and increase penis size.

“Rated #1 by the Scientific Community,” and “New Breakthrough Male Augmentation Formula,” read some of the many advertisements on the official website.

Since these statements have not been evaluated by the Food and Drug Administration, I looked closer at the ingredients.

What’s Under the Lid?

Longinexx ingredients are featured in a vasobolic proprietary blend. The manufacturer doesn’t provide ingredient amounts. This makes it impossible for users to know how much of each ingredient they are ingesting in one serving.

Here are some ingredients in the formula:

Proprietary Vasobolic Blend

Xanthoparmelia Scabrosa
This ingredient is raved about by the male enhancement community as being highly potent and effective for treating erectile dysfunction. However, no clinical studies support its use. Also, it is regarded as possibly unsafe due to toxins found in the ingredient that result in cell death. [1]

L-Arginine AKG
This ingredient was studied for its ability widen blood vessels to improve blood. For this reason it is thought to improve sexual function.

One study administered an arginine AKG-based supplement (12 g per day) to 24 men over a 7-day period as they underwent resistance-exercise. Results show the supplement increased arginine levels. The researchers note the brachial-artery blood flow observations and hemodynamics “can only be attributed to the resistance exercise.” [2]

Arginine is a nitric oxide precursor and enhances blood flow to the penis. However, because the manufacturer doesn’t provide arginine AKG amounts, it is impossible to know if there is enough in Longinexx to produce similar benefits

Extract Tribulus Terrestris
This ingredient was shown to improve semen count when administered in 12 g daily over a 60-day period. [3]

A promising animal study analyzed tribulus terrestris’ ability to improve sexual function in male rats. Dose-dependent improvements were seen as a result from tribulus terrestris supplementation, such as an increase in mount frequency, intromission frequency, and penile erection index. [4]

Butea Superba
This ingredient is used to treat erectile dysfunction and sexual desire.

One study shows butea superba improved sexual function in 82.4% of patients during a 3-month randomized, double-blind clinical trial. Improvements were seen in 4 of 5 descriptive evaluations of the International Index of Erectile Function questionnaire. [5] Unfortunately, I was unable to find clinically-effective doses.

Osthole
An O-methylated coumarin, osthole is shown in in vitro animal studies to relax the muscles in the penis.

One study shows osthole had relaxant effects on the corpus cavernosal penis tissues. [6]

This has implications of improving erection quality by allowing more blood flow for stronger, harder erections. However, I was unable to find in vivo, human clinical studies.

Eurycoma Longifolia
Eurycoma longifolia enhanced semen parameters such as sperm concentration, volume, and motility in test subjects suffering from idiopathic infertility. The dose studied was 200 mg daily over several months. [7]

Are Users Satisfied with Longinexx?

User reviews are limited to Amazon.com. Longinexx receives mixed reviews among users. Some users noted firmer erections and width gains while others did not experience the same results. Here is what users are saying:

“So doesn’t work at all,” says Carrel J. Brown. “Please save yourself time and a headache. If you are looking for results try a pump or surgery.”

Another user, Mark, says, “Erect length had no change after a few months. Flaccid length did increase…” He says erections are harder “but not any practical difference.”

JD is a film star and studies different male enhancement products. “This product just didn’t meet the needs for my performance. Take a hour or more to process, Yes you will feel the stiffness which is a PLUS.” He saw a difference in width but not in length or stamina.

“I like this product. It works well for me with no side effects. Takes about two weeks before you actually see a difference in girth and hardness. However, as with the increase in girth, I have not seen much difference in overall length. Good product.”

What Are the Side Effects?

In the FAQ section on the official website, Longinexx.com, the company answers questions regarding size effects. “Absolutely zero,” says the company.

However, I found xanthoparmelia scabrosa as being possibly “unsafe” rather unsettling. [1] Whether this ingredient is formulated in high amounts in Longinexx is unknown.

What Is the Best Way to Take Longinexx?

Unlike some male enhancements that are taken only before sexual activity, Longinexx should be taken daily. However, the company isn’t too specific on explaining how to take Longinexx. The site simply says to take 2 capsules every day. Whether these pills are taken together or separate is unknown.

I suggest taking 1 capsules the first couple days to assess tolerance. If no adverse side effects occur, increase the dose to 2 capsules per day.

Where Is the Best Place to Purchase It?

Longinexx is available for purchase through Longexx.com and Amazon.com. I found the best deals available through the official website. One bottle of Longinexx provides a 30-day supply and retails for $39.99.

Longinexx.com offers multiple-bottle deals to save money.

• 3 bottles – $79.97
• 5 bottles – $119.95
• 7 bottles – $159.93

Also, the official website guarantees Longinexx products with a 60-day 100% money-back guarantee.

If you are not satisfied with Longinexx, send back the unused portion within 60 days of the purchase date for a refund.

Should You Try It?

Longinexx ingredients are promising. But, the unlisted ingredient amounts make it difficult to tell if Longinexx is formulated according to clinical studies. This is a big downside.

User reviews are mixed. However, the money-back guarantee makes it possible for users to try it risk-free.

It isn’t the best male enhancement supplement available, but it may be enough to treat sexual dysfunctions in some individuals.
