Testosterone Mega Boost Red™ is a unique-2-in-1 formula for men of all ages. It is designed to help enhance male vitality and performance by boosting testosterone levels already within the normal range, and supporting nitric oxide to enhance male physical response during any physical activity. The key ingredients at the center of this amazing product are LJ100® Longjack and L-Citrulline.

Testosterone Boost:  As men age, testosterone levels start to decline. This male sex hormone is known to promote vitality and is involved in mood, sex drive, muscle mass and muscle strength. This formula features LJ100® Longjack, a patented extract that preliminary research suggests help maintain testosterone levels already within a normal range.

Nitric Oxide Boost: Nitric Oxide is a naturally-occurring compound in the body that plays a key role in cardiovascular health.
