Motivation is not a one-time job. You cannot be motivated for the entire lifetime. It is similar to charging the battery of your mobile phone. Frequently, your cell phone battery goes off and you have to recharge it again. Similarly, you also feel drained off, your mood becomes low and you feel depressed for some period of time.

What Is MuscleTech Test 3X SX-7 Black OnyX?

MuscleTech Test 3X SX-7 Black Onyx is a hardcore testosterone-producing formulation that is powered by three vital ingredients.

Manufacturer Information And Claims About MuscleTech Test 3X SX-7 Black OnyX

GNC claims that 3X SX-7 Black Onyx is the powerful and advanced testosterone-boosting supplement available in the market these days. You can find hundreds of testosterone-boosting supplements in the market. But you cannot find a single one that is supported by a scientific study. MuscleTech is an exception to the rule and stands out in the market because of its unique point.

Claims Image

The three key ingredients used in 3X SX-7 have been proven in clinical studies. According to the study outcomes, these ingredients reduce estradiol and catabolic hormones and increases testosterone. A scientific study outcome is sufficient to prove the customers how effective the supplement is. No other advertising strategic or marketing gimmick can help a company to increase sales but a true and genuine study result can definitely pull more and more customers.

Features and Specifications

It is testosterone-increasing formulation that works better for hardcore gainers.

The ingredients added in this supplement are supported with a separate clinical study.

It consists of vitamins, minerals and naturally extracted herbs such as tribulus fruit extract and olive leaf extract.

How Does It Work?

A multi-platform formulation, 3X SX-7 Black Onyx boasts of providing three essential benefits to men as follows:

Increase in the free testosterone levels

Maintenance of testosterone-to-estradiol ratio through reduction of estradiol

Reduction of the primary catabolic hormone

Due to the presence of D-Aspartic Acid in this powerful supplement, clinical studies have observed that testosterone level increases by about 40 percent and luteinizing hormone increases by about 30 percent.

Boron contained in this supplement has been proven in human clinical studies with a point of observation that estradiol can be reduced and testosterone can be increased within a short period of 7 days. Thus, your body gains free testosterone, which is in highly active form and is essential for the strength-building process of a man.

Another essential ingredient known as Withania Somnifera, this supplement gains dynamic powers and thus, it decreases the key catabolic hormone by nearly 14.5 percent, which is impressive.

The yacon and olive leaf extracts contained in 3S Sx-7 Black Onyx are unbeatable in delivering virility and strength to men.

Test 3X X7 Black OnyX Review Image

Dosage: 4 Caplets / day.


Separate clinical studies are available to support the significance of the three key ingredients contained in 3X SX-7 Black Onyx.


If you compare its benefits with its cost of $59.99, then you will realize that this is a costly deal. You cannot gain tremendous effects as compared to its higher price.

The manufacturer states that it provides extreme muscle strength and development, but does not state anything about a man’s libido and its improvement. Hence, we are unsure how it helps in improving a man’s sexual life.

The experts at Propura Limited racked their brains to develop a supplement that comprised of all the essential elements of 12 natural testosterone boosting ingredients. It is not always necessary to boost testosterone. It is essential to beat the obstacles that are in the path of testosterone formation.

PrimeMale does this job and hats off to the team at Propura Limited.

The experts at Roar Ambition Limited analyzed the needs of bodybuilders. Most of the bodybuilders looked for a testosterone supplement that is not just a box of artificial testosterone but which is natural and fortifying for the body.

They wished not to look strong but also to feel strong and be strong. Hence, TestoFuel supplements were created in order to fortify the organs, muscles and cells of the bodybuilders by working on their testosterone levels.

As they have to put a lot of energy during an exercise session, they tend to get tired.

TestoFuel fights with this resulting fatigue and lets them perform at their peak level next day morning.
