supplements are popular among men and women who are interested in vitality, energy, and heightened experience. Our proprietary herbal blend combines with three other powerful herbal enhancement ingredients that include maca, mucuna, and Polypodium vulgare (also known as rock fern). Often found in health and endurance supplements, these natural herbal ingredients collectively can help with blood flow, energy and endurance. All of this may contribute to a positive impact on performance. Potency is important when it comes to performance. Desire-x contains high-potency dose of over 800 mg in each two-capsule serving. All Mason Natural products are produced in a Gmp certified facility and laboratory tested for purity.
