Our Bulgarian Tribulas Extra helps to maintain a healthy reproductive system and libido in men. The formula helps nourish the reproductive system and soothes the central nervous system, while enhancing sexual potency through increased peripheral circulation. Trophic’s Bulgarian Tribulus Extra provides nutritional support for the male reproductive and endocrine systems. Bulgarian Tribulus is typically used to increase athletic performance, testosterone, sperm counts, sexual desire and potency in men. Ginko biloba is thought to increase circulation both to the brain and the genitals. Saw palmetto and lycopene both support and protect reproductive health. North American ginseng (BC grown) enhances endocrine function. Fresh freeze-drying of the herbs maintains their biologically active constituents for the highest potency and therapeutic potential.
