America's #1 selling weight loss supplement brand Research-backed weight loss ingredient. Full transparency. All power.

New Test HD Lean Build Black Onyx is the most advanced 2-in-1, testosterone-enhancing and musclebuilding pill.

It’s built with multiple scientifically researched ingredients shown in four separate human clinical studies to boost free testosterone, enhance performance and build lean muscle.

Scientifically researched testosterone enhancer

Featuring researched doses of KSM-66 ashwagandha and boron shown in separate human clinical studies to promote total testosterone and boost free testosterone – most competitors have none!

Free testosterone is the most active form of testosterone and is critical to initiating the muscle- and strength-building process.

Test HD Lean Build Black Onyx is also armed with maca, tribulus, safed musli and longjack, plus zinc to help support optimal testosterone production within the normal range.

Powerful musclebuilding & strength

Three ingredients make this a powerful performance enhancer: exclusive and patented Cindura, mTOR-activating PEAK ATP and clinically dosed KSM-66. Cindura has been clinically shown to support muscular strength, boost endurance and increase mass.

What’s more, researchers believe Cindura may help prevent muscle breakdown. In fact, in a 6-week clinical study, subjects taking the amount of Cindura found in 3 tablets of Test HD Lean Build Black Onyx significantly increased their muscular endurance by an average of 6.6 reps vs. just 2.2 reps by the placebo group when tested via leg extensions.

Check out the gold standard clinical studies below to see how Cindura, PEAK ATP and KSM-66 are clinically shown to enhance performance, boost strength or increase lean muscle.
