Prelox Summary

Last Updated: May 16, 2024


A patented combination of L-Arginine and Pycnogenol®, (according to the official website) Prelox® is marketed as a male sexuality booster. It is manufactured by Horphag Research, whose worldwide base is in Cointrin/Geneva, Switzerland.

Prelox® claims to do three things: (1) potentially treat erectile dysfunction; (2) improve a man’s libido; and (3) restore a man’s confidence by putting an end to performance anxiety.

We will look at the claims and see how Prelox® fares against the other male enhancement products, which we have summarized in the past.

Ingredients at a Glance

As mentioned, the two main ingredients of Prelox® are L-Arginine and Pycnogenol®, both of which are touted as blood flow promoters to the penis. The two-ingredient formula is said to be free of side effects, which in the land of male enhancers doesn’t really inspire confidence. We’re sure the saying “less is more” works for some products but not for penis enlargers and/or male health supplements.

Of course, we will not dismiss L-Arginine’s effects when it comes to boosting muscle mass and in supporting the functions of the male reproductive system. However, the effect is incomplete if it’s not in combination with other potent male enhancement ingredients such as Yohimbe, Epimedium, Tribulus terrestris, and so on.

As for Pycnogenol®, which is also known as French Maritime Pine Bark Extract, we are not discounting its benefits when it comes to fighting infections and diseases such as hypertension, ADHD, and type II diabetes. But we’re talking about male enhancement here, and we’re not sure that it really delivers on its promises as a male sexuality aid.


  • Product will likely benefit men who needs to boost his sperm count.
  • The official website is very interactive and very comprehensive.
  • Testimonials are available on the website.Provides discounts on multiple bottles


  • Product fails as a male sexuality booster due to lack of key herbal ingredients such as Yohimbe, Epimedium and Tribulus terrestris.
  • Product is sold via distributors instead of being available on the official website. The best deal should always be offered on the main site.
  • Overviews (not the testimonials available on the website) are not very positive.

Final Thoughts

As a standalone product, Prelox® will probably not meet a man’s expectations when it comes to enhancing his performance in the bedroom and his genitalia. While it has been shown to help with sperm production, the two-ingredient formulation makes us wonder if Prelox® is better suited as a weight training supplement than as a male enhancement product.

Should the manufacturers reformulate, we suggest the inclusion of Yohimbe, Epimedium and Tribulus terrestris – ingredients that are proven to enhance male sexuality and increase the dimensions of a man’s penis.

As a natural male enhancement supplement, Zenerx scores high in safety. But by picking little known ingredients over a potent herb like Yohimbe, the manufacturer may have decreased the product’s ability to increase the flow of blood to the penis, which is needed to enhance erections. While Zenerx is a good natural male enhancement supplement, it won’t hurt to do more research and find other alternatives that will best suit your needs.
