Boost Free Testosterone in 7 Days – Test HD® Black Onyx® features four separate ingredients backed by separate human clinical studies shown to boost testosterone or combat cortisol – most competitors have none! One of those ingredients is shown to increase free testosterone and decrease estradiol in a little a 7 days.

Testosterone is Critical for the Strength Building Process – Test HD® Black Onyx® is the only testosterone-boosting formula to combine clinically researched doses of Sensoril® Ashwagandha, Primavie® Shilajit and D-aspartic acid, plus the much sought-after ingredient longjack. Many competitors using these ingredients only include supportive doses or hide the amounts in proprietary blends, making the other guys inferior to our fully disclosed formula.

Free testosterone is the most active form of testosterone, and is critical to initiating the muscle- and strength-building process, as well as supporting performance.
