Test Subjects Significantly Increased Testosterone

Test 3X SX-7® Black Onyx features a precise 3.12g dose of sodium D-aspartic acid. Sodium D-aspartic acid (DAA) is a naturally occuring amino acid found in the neuroendocrine tissues of humans that has been shown to increase testosterone and luteinizing hormone while staying within the normal healthy range.

In one study published in Reproductive Biology and Endocrinology , 23 men were given the same daily dose of sodium D-aspartic acid in Test 3X SX-7 Black Onyx for 12 days. Researchers found that after 12 days, subjects had significantly increased luteinizing hormone and serum testosterone levels!

Sodium D-aspartic acid utilizes your body’s very own internal mechanisms to raise testosterone, which means there is no feedback inhibition involved and no need for post cycle therapy (PCT).

Decreases Cortisol

The superior Test 3X SX-7® Black Onyxformula also contains the cutting-edge ingredient Withania somnifera, which is shown to reduce cortisol.


Sensoril® Ashwagandha (Withania somnifera) is a powerful adaptogen that has been scientifically shown to significantly lower serum cortisol levels. In a double-blind, placebo-controlled human study published in the Journal of the American Nutraceutical Association, researchers gave 19 subjects 125mg of Sensoril® Ashwagandha (Withania somnifera) each day. This is the exact type of Withania somnifera delivered in Test 3X SX-7 Black Onyx and also the exact same dose. After two months, researchers measured stress hormones in the body and found that cortisol levels decreased significantly!


When cortisol levels increase from frequent, intense training, testosterone levels can drop. Test 3X SX-7 Black Onyx contains Withania somnifera that lowers cortisol.

High levels of cortisol can hinder muscle development and decrease muscle tissue. This is because cortisol functions to increase the breakdown of protein and facilitates its conversion into forms that can be used as energy sources by your body, and prolonged cortisol elevation can lead to muscle breakdown.
