AMS PenaMax is an all-natural dietary supplement formulated for men who are looking to increase stamina, endurance, and improve overall sexual performance in an entirely natural manner. It elevates libido and sexual desire and helps restore normal erectile function. Ingredients found in the supplement include Acetyl-L-carnitine, Propionyl-L-Carnitine, L-Arginine, Ginkgo Biloba and Butea Superba. Butea superba Roxb (Leguminosae) has been found by studies to be effective in enhancing penile erection by increasing nitric oxide and sperm motility. L-Arginine is a semi-essential amino acid produced in small quantities by the body. It is a prime ingredient used as a base for the formation of nitric oxide (NO), which relaxes the muscles surrounding the blood vessels of the penis. Acetyl-L-carnitine and propionyl-L-carnitine boost energy metabolism. Ginkgo Biloba also contributes to good blood circulation, thereby improving erection. Indeed, this plant extract optimizes blood flow and stimulates circulation, making this dietary supplement recommended for men who wish to enhance their erections.
