Muscletech Test HD 90ct (US Version)

Test HD is designed to increase testosterone production to increase muscle building activity.

High Performance Testosterone Booster 

Engineered for serious athletes focused on maximizing strength, Test HD® is the complete testosterone boosting formula. Optimizing natural testosterone levels within the normal healthy range in men can impact performance, support increases in muscle mass, and help you take your training to another level.

Increase Total Testosterone Levels 

Test HD® delivers the key ingredient PrimaVie®, a high quality, scientifically engineered, purified shilajit from the Himalayas. It has been clinically studied in men and shown to increase total serum testosterone levels as documented after 90 days. In another study, shilajit was shown to boost ATP levels in just 15 days! ATP is a critical energy source used during workouts.

Boost Free Testosterone in just 7 Days 

Test HD® is engineered to support free testosterone. Free testosterone binds to receptors within muscle to initiate the muscle building process. This formula delivers a full dose (in 2 caplets) of the scientifically validated key ingredient boron. A clinical research trial in men showed its effectiveness in boosting free testosterone levels and even combating estradiol in just 7 days. 

Take Training to the Next Level 

Packed with other well-known ingredients, Test HD® also includes stinging nettle root extract, tribulus extract, safed musli extract, and zinc. If you're constantly on the lookout for ways to increase your testosterone and level up your training, look no further.
