MuscleTech Test HD Testosterone Booster aims to deliver more than a regular testosterone booster by addresing more than one hormonal pathway with the aim of increasing whole body anabolism by more than can be achieved via simple elevation of testosterone alone.

Test HD utilises four different compounds which in one way or another are designed increase total or free testosterone, as well as enhancing libido. Perhaps the star ingredient in Test HD is the inclusion of a clincally dosed form of shilajit, a compound which grows in the Himalayan mountains and which comes here in the patented PrimaVie® form which is standardised and purified to deliver high levels of bioavailability.

This particular version of shilajit has also been shown to significantly enhance total serum testosterone levels in a study where users took this for 90 days at the dose in Test HD. As a bonus, PrimaVie® has also been shown to promote higher levels of ATP, a source of energy used to generate any form of human force whether it be the movement of muscles or beating of your heart.

Test HD also includes stinging nettle root which increases the portion of testosterone that is unbound by SHBG (making it usable by your body) as well as the libido enhancing tribulus and boron citrate.
