Loyal fans of our top selling pro-sexual product Vitrix may have noticed a few formula tweaks over the last few years. While we have introduced what we believe to be some of the most potent formulas in the pro-sexual category, our group of formulation perfectionists are always in search of the most effective ingredient combination that could outperform the original Vitrix formula. We were able to secure a small micro batch of the hard to get, extremely potent German tribulus, that was in the original Vitrix, and blended it with the most potent form of Eurycomia Longifolia called LJ100. LJ100 is the only science backed version of Eurycomia with clinical data from human trials showing an increase in sexual performance and satisfaction, coupled with increased energy and feelings of wellbeing (1,2,3). You will be hard pressed to find any herbal ingredient with more human research showing increases in sexual health and performance as well as pro-testosterone effects (1,2,3,4,5,6).
Lastly, citrulline replaces arginine in this formula. Citrulline is believed to be a pro-erectile supplement because it is the more potent precursor for arginine, which itself is the amino acid from which nitric oxide (NO) is produced. NO acts as a neurotransmitter in the penile nerve fibers and will increase blood flow though vasodilation of the smooth muscle cells. One of the main benefits of Citrulline is that it was found to increase erectile strength and hardness (7). Give it a try and let us know if it doesn’t warrant a thumbs up.
