Powerful musclebuilding & strength

Formula re: Contains

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.

Formulation re: Other

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.
