Product Information



Testosterone - Performance - Strength

800mg Cindura® - 400 Peak ATP® - 600 KSM-66® - 250mg Tribulus

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 showing in four separate human clinical studies to boost free testosterone, enhance performance and build lean muscle.

Scientifically Testosterone Enhancer -
Featuring researched doses of KSM-66® ashwaghadha and boron shown in separate human clinical studies to promote total testosterone and boost free testosterone – most competitor’s 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 the also alarmed with maca, tribulus, safed musli and longjack, plus zinc to help support optimal testosterone production within normal range.

Powerful Musclebuilding & Strength -
Three ingredients make this powerful performance enhancer: exclusive and patented 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.

Great product with amazing results
This testosterone booster gave me great results! I felt much more energized and alive in all aspects of my life. It gave me a good energy boost as well as the gains I'd been hoping for in the gym. The ingredients in Test HD are clean and a good variety from all aspects of research. I'd recommend this to everyone struggling from the effects of a lack of testosterone!

Test Booster Experience
I was skeptical of this product, claiming that it "enhances performance and builds lean muscle".
The first thing I noticed after taking this product was a higher base level of energy throughout the day. I typically drink 3-4 cups of coffee per day but found myself only needing 1-2.
My workouts were the same intensity as before, but I noticed I was able to recover a bit more quickly between sets after about a week and a half.
Overall, this product seems to do what it claims - promote strength building and enhance performance
