The Scitex #1 Choice for 2016 is Zenerx

Zenerx is our top pick this year for male enhancement. We made this decision based on the quality of the ingredients used, the length of the guarantee and the numerous customer testimonials. Not only that, the product is backed by a medical doctor.

Does it Work?

Irexis claims ‘100% Guaranteed Bigger Stronger, Firmer Erections.’

The product contains two scientifically proven substances which effectively aid in male enhancement:

  • Tribulus Terrestris, which increases testosterone levels and sexual desire
  • L-Arginine, which stimulates nitric oxide, relaxing the muscles of the blood vessels leading to the penis, increasing blood flow resulting in a firmer, longer lasting erection

Irexis also contains a number of other natural ingredients such as Zinc, Ginseng, Muira Puama and Catuba bark extract, all of which are purported to have aphrodisiac properties.

However, Irexis also contains Yohimbe (also called yohimbine), a substance produced from the bark of an African tree of the same name, widely used in the region as an aphrodisiac.

In fact, Irexis contains more Yohimbe than any other single ingredient, according to its own supplemental fact sheet.

The FDA has identified Yohimbe as a potentially dangerous substance, as it has caused a host of health issues, from headaches, dizziness, anxiety, insomnia, hallucinations, hypertension, seizures and renal (kidney) failure.

We strongly caution against the use of any male enhancement product which contains Yohimbe.

Side Effects

Although the Irexis website states that when using the product ‘There are no reported adverse side effects! However, about 10% of users experience mild head flushing and a mild temporary headache, due to Irexis’ strong blood circulation action. Generally, this goes away after the second or third time taking Irexis,’ it does not indicate any of the possible negative effects of Yohimbe.

Irexis should not be taken by people with shellfish allergies.

Irexis comes with a 90 day guarantee, but customers must first contact the company 30 days after purchase to receive a return authorization, but have 60 days from that period to arrange their refund.

The website Terms of Use also describes the Irexis version of an auto ship program. This is a common practice within the male enhancement industry, which automatically bills customers and ships additional supplies monthly, even though customers believe they are making a single purchase.

In the case of Irexis, the manufacturer Lab88, will auto ship the product every 24 days, and will only allow cancellation of the program after a 2nd order is received, and then have the audacity to charge an ‘Early Termination Fee.’

There are no references to any clinical study conducted on the effectiveness of Irexis, nor are there any customer testimonials promoting it.

Is it a scam?

The Irexis website offers a good deal of information about how they claim their blend of all natural ingredients will produce a firmer, longer lasting erection, but provides little in the way of evidence.

This is not the best indicator that the product actually provides the results it claims. Therefore, we recommend against the use of Irexis as a viable male enhancer.
