Neurobiologix Male Support Formula (formerly known as Andro Enhance) works by naturally optimizing the body's own free testosterone levels. Created by Dr. Kendal Stewart, is designed to help maintain healthy testosterone levels and youthful function and provide libido support. Testosterone is a male sex hormone that plays a key role in the development of the male reproductive system. It also stimulates increased muscle and bone mass as well as hair growth. Testosterone affects the way males store fat in the body and even red blood cell reproduction. When testosterone levels decrease, it increases the risk for a number of things including: Low libido, Weight gain, Low energy and fatigue, Mood swings, Self-esteem issues, and Thinning bones. Research has shown that horny goat weed, maca, and tongkat ali promote positive changes in men and women suffering from low energy and libido, a sign of decreased testosterone levels. According to some studies, these ingredients can also boost prostate health and provide libido support. Recommended Use: 2 capsules daily preferably with food 1 to 2 hours prior to physical activity or as directed by a healthcare professional. Do not exceed two (2) capsules daily.
