A safe, natural way to support healthy sexual performance in men & rekindle a robust and satisfying sex life.

Gene Smart Endura-Max

More than 50% of men between the ages of 40 and 80 experience some kind of lag in their sexual performance. But don’t assume a lagging sex life is just part of getting older.

The Gene Smart team found a safe, natural way to promote nitric oxide production—a way to ensure lasting, spontaneous erections, whenever the moment is right.

But it's not l-arginine. It's another far better amino acid called l-citrulline, and it’s the key ingredient in Endura-Max.

Your body uses l-citrulline to create l-arginine. But, unlike l-arginine, it isn’t broken down in the liver or the small intestine. So, it actually creates l-arginine in your body better than l-arginine itself—and the science proves it!

That means, in as little as 30 days, you could be enjoying...

  • More sex...
  • Stronger erections...
  • More sexual satisfaction...
  • Better confidence in the bedroom...

And, because the ingredients in Endura-Max work to help promote healthy circulation, it comes with a whole host of side-benefits, like:

  • Healthy, balanced blood pressure
  • Improved circulation
  • Better overall cognitive functioning
  • Less LDL cholesterol oxidation

But we didn't stop there. The l-citrulline in Endura-Max is combined with a standardized beet root extract. Studies show that, not only can it help promote erection-strengthening nitric oxide, it can help increase exercise capacity and improve muscle recovery.

Gene Smart takes pride in only offering REAL support backed by REAL science.

Every natural health solution we develop is guaranteed to be based in the latest scientific research and gene-based nutritional health science.

EnduraMax is based on today’s most cutting-edge science and clinically studied ingredients. It’s guaranteed to give you the results you’re looking for, or your money back.

4. What are the ingredients and what are they good for?


Per 4 capsules



1,500 mg

  • Citrulline is a dietary amino acid that is converted in the kidneys into arginine—a precursor to nitric oxide.
  • Nitric oxide is helpful for maintaining proper relaxation of the blood vessels.
  • Nitric oxide helps maintain proper flexibility and elasticity of the blood vessels which is critical for optimal blood flow.
  • Nitric oxide is the primary neurotransmitter that stimulates penile erection.
  • Supplementing with citrulline significantly increases the amount of arginine circulating in plasma. This increase lasts longer than directly supplementing with arginine.
  • One small study suggests that supplementing with 1,500 mg of citrulline may help improve erection hardness. In this study, half of the men taking citrulline saw a significant improvement and reported being very satisfied.

Beet Root Extract (standardized to 2% nitrate)

500 mg

  • Beet roots are a natural source of dietary inorganic nitrate.
  • The body naturally converts these nitrates into the vasodilator nitric oxide.
  • Nitric oxide helps improve circulation and blood flow, and helps stimulate penis erections.
