Product Information



Testosterone is a male sex hormone that plays a key role in developing and maintaining masculine characteristics. It is known to promote vitality and wellbeing and is involved in mood, sex drive, muscle mass and muscle strength. As men age, testosterone levels start to decline. Testosterone UP™ is an advanced pro-male testosterone support formula that is enhanced with physical peak-performance boosters that can help men of all ages.*

Boost Testosterone: This unique formula is designed to boost testosterone levels already within a normal range.* At the center of this mechanism is LJ100® Longjack, a patented extract that preliminary research suggests, helps maintain testosterone levels already within the normal range.* OptiZinc®, a patented form of zinc, is a trace mineral required for numerous vital cell functions, including growth and development as well as sexual health.*

Testosterone UP™ has also been formulated to enhance performance and vitality in men.* Ginseng extract is traditionally used as a tonic to revitalize the body and is known as one of the best botanicals for increasing feelings of energy, improving mental capacity and physical performance.*
