T-UP® Testosterone Booster is raising the bar in natural testosterone elevation by bringing you scientifically researched D-Aspartic Acid in a clinical amount. Unlike many products that claim to increase natural testosterone, our effects are real and supported by a clinical study.
In this clinical study, the D-Aspartic Acid used in T-Up led to an average 42% increase in testosterone after only 12 days of use.* Click Here to Read Study
An elevation in testosterone levels is associated with more muscle gains, strength increases and enhanced recovery. Just one serving a day is needed!
* Topo et al., 2009, Reprod. Biol. Endocrinol. 200, 7:120. Study lasted 12 days and showed an average increase of 42% in total testosterone levels. The effects of D-Aspartic Acid on free testosterone were not investigated. Although only free testosterone provides the muscle enhancement and other benefits associated with testosterone, many experts agree that an increase in total testosterone is accompanied by a similar increase in free testosterone.

At Nutrex we are proud to know that we are one of the few sports nutrition companies who own and operate their own production facilities. While it's true that Nutrex is one of the world's largest producers of sports nutrition products, we remain focused on being recognized as the best.
In fact, our requirements for raw materials are so strenuous that it's not unusual for Nutrex Quality Assurance Technicians to reject entire truckloads of raw materials that do not meet our high standards. We like to think that we take as much pride & care in crafting our award-winning supplements as our consumers do with crafting their physiques and fitness accomplishments.
