MuscleTech will soon be releasing Test 3X SX-7 to their newly established Black Onyx series, which also includes Hydroxycut Sx-7 Black Onyx and PhosphaGrow SX-7.

From the label we can see the company claims it is the “most powerful & hardcore testosterone boosting formula.”

I wanted to take a closer look at MuscleTech TEST 3X SX-7 to see if it truly is a hardcore testoster-boosting and able to compete with other testosterone-boosting supplements.


MuscleTech TEST 3X SX-7 will provide several different ingredients, all with individual ingredient amounts include, which is a benefit to consumers. No proprietary blends here, which is already a plus in my book.Ingredient Profile

Here’s a closer look at some key ingredients in TEST 3X SX-7’s formula:

Like many other testosterone-boosting supplements, TEST 3X SX-7 provides a good amount of zinc (30 mg) per serving. Zinc is a mineral that is supplemented with to support healthy testosterone levels. Deficiencies in zinc have been shown to result in subpar testosterone levels.

D-Aspartic Acid (3.12 g) is a well-studied ingredient that is supplemented with to increase natural testosterone production. Studies show that D-aspartic acid has the ability to regulate the release of testosterone and luteinizing hormone, a hormone that stimulates testosterone secretion. [1]

Another key testosterone-boosting ingredient is tribulus fruit extract (250 mg), which athletes supplement with to boost natural testosterone levels.

Boron Citrate (200 mg) is another key mineral that has been shown to reduce estrogen while enhancing free testosterone levels at the same time. [2]

The ingredient profile looks pretty impressive. I can’t wait to read the user reviews and see how they respond to the carefully selected formula.

How Should You Use TEST 3X SX-7

To use MuscleTech TEST 3X SX-7, you should take 1 serving once a day with water, each serving consists of 4 caplets. You shouldn’t exceed more than 1 serving in a 24-hour period.

To optimize your testosterone levels, you should also implement regular resistance exercise and follow a healthy eating regimen to combat weight gain, which is a factor shown to be a culprit of low testosterone.

If you’ve never tried a testosterone-boosting supplement, I suggest possibly starting with a smaller serving just to assess tolerance and how you respond to the ingredients.

Pricing and Availability

It doesn’t look like MuscleTech TEST 3X SX-7 is available for purchase yet, but will be shortly- perhaps this month.

Third-party websites have Test 3X SX-7 set to retail for $79-89 per bottle, with each bottle providing a 30-day supply. This price is a bit steep for a testosterone-booster that may or may not work for you.

If you are looking for an affordable natural testosterone-enhancing supplement, this may not be your best bet. You can find a lot of other competing supplements for a fraction of the price.

That being said, if you are willing to fork over some cash for what looks like an impressive ingredient formula, MuscleTech TEST 3X SX-7 may be worth waiting for.
