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.

Light years better than Nugenix. Felt an immediate increase in energy and libido AND I consistently work out longer and recover faster.

Good Supplement!
I have used plenty of test boosters over the years, this is definitely a good one. Good increase of energy, allowing for better/harder workouts. Would definitely recommend to anyone in the market for a good test boosting product, the only reason i give this product a four is because of he taste, it takes a little getting used to.

Test Booster And More
I am a younger guy, so Test Boosters aren't a necessity like they will be later. However, I had a great boost of energy, and feel like my workouts are counting more than they did before. It has some of the same ingredients that other MuscleTech products do that I love. It's a solid enhancement!

A great testosterone booster
This is a very good testosterone booster. I would definitely recommend getting it. I will be buying this again for sure. I’ve gained a nice amount of lean muscle mass waiting till I’m completely finished to see how much total. I’ve also noticed that I have a lot more energy then normally without it.

Pretty Solid Product
This stuff surprised me and actually worked!
I used it for about a month and it helped my lifts, let me lose a little extra fat, and increased my energy. I would advise you to try it out if you can afford it.
