DescriptionTHE MOST POWERFUL & HARDCORE TESTOSTERONE-BOOSTING FORMULA*
Test 3X™ SX-7® Black Onyx™ is the most advanced testosterone-enhancing pill on the market today. Many testosterone-boosting pills aren’t backed by a single human clinical trial. But Test 3X™ SX-7® Black OnyxTM features three powerful ingredients backed by separate human clinical trials that are actually shown to boost testosterone, decrease estradiol and reduce a key catabolic hormone.*
How Does It Work?
Test 3X™ SX-7® Black OnyxTM has a multi-platform formula that delivers three distinct benefits. First, it increases free testosterone levels. Then, it works to optimize the testosterone-to-estradiol ratio by decreasing estradiol. Lastly, it reduces a key catablic hormone, making it a truly complete and powerful testosterone-boosting formula.*
Test Subjects Increased Testosterone by Over 40%
Test 3X™ SX-7® Black Onyx™ features a clinical dose of D-aspartic acid, shown to increase testosterone by over 40% and increase luteinizing hormone by over 30% while staying within the normal healthy range.
Boost Free Testosterone in Just 7 Days
Test 3X™ SX-7® Black Onyx™ is also formulated with a powerful and concentrated dose of boron that is shown in human clinical research to increase free testosterone and decrease estradiol in as little as 7 days. Free testosterone is the most active form of testosterone and is critical to initiating the strength-building process.*
Decreases a Key Catabolic Hormone by 14.5%
What makes Test 3X™ SX-7® Black Onyx™ truly unbeatable is the use of the advanced ingredient Withania somnifera, which is shown to reduce a key catabolic hormone by an astonishing 14.5%. Test 3X™ SX-7® Black Onyx™ also delivers yacon root and olive leaf. Experience its shocking power and potency for yourself.*

You won't want to come off this test booster!
This is the most test boosting ingredients you will find in one single product. I felt an amazing amount of overall happiness, energy, libido, and increased recovery time. If you haven't found a test booster yet try this one and you will not regret it.

Great Test Booster!
I stacked this with MuscleTech's Hydroxycut Non-Stim SX-7, CLA 4X SX-7, Ultra Carnitine 3X SX-7, & Apple Cider+ SX-7 for the ultimate weight loss stack while preserving muscle mass. I've been taking these products for 2.5 weeks & loss 2.5 lbs, with no loss in muscle mass. My overall appearance, looks like I've actually increased my muscle mass while decreasing my body fat mass. I am in a calorie deficit, tracking my macros to control all variables. I definitely recommend this product by itself or in a stack to help reach your fitness goal.

Great T booster
One of the BEST test products out there. Non proprietary blend bs. I’m sure everyone’s results will be different but for me I was able to notice a spike in my T levels. Will continue to use and hopefully see greater results once I stack it with my workout supplements. But for now. Great product I would definitely recommend
