Product Information


Ultimate Test Booster
Boosts Testosterone* - Anti-Estrogenic*

Technology Meets Efficacy Without Compromise
Advanced Dual-Capsule Technology
This breakthrough, patented process physically isolates distinct active ingredients into two separate capsules. This allows for ingredients to be maintained in their preferred active states. It also allows for fast-release liquid and rapid-dispersion powder co-release when you need it most!

Ultimate Test Pill
Test 4K SX-7® Revolution provides a precise dose of boron, shown in human clinical research to boost free testosterone and decrease estrogenic effects in just 7 days! This innovative formula also features ashwagandha, a powerful adaptogen that has been scientifically shown to significantly lower serum cortisol levels. A neverbefore- seen combination of tongkat ali extract, maca extract and safed musli extract round out this truly unique formula.*
Fast-Release Liquid Pill
Delivers a concentrated source of rapidly absorbed MCT oil as well as vitamin D, which is a precursor to many metabolic and biological processes.
Advanced Dual-Capsule Technology
Introducing Test 4K SX-7® Revolution, the most advanced dual-capsule testosterone-boosting pill available. It combines a patented process that features two separate capsules to deliver a potent combination of multiple clinically researched key ingredients. They work to rapidly boost testosterone and lower cortisol.*

Dual-Capsule, Pill-Within-A-Pill Technology
Introducing the world’s most advanced new capsule technology that harnesses the power of a super-concentrated, micronized powder capsule suspended within a highly bioavailable liquid capsule. The rapid-release liquid is isolated from the micronized powder, separating the ingredients in their most stable inherent states until the moment of absorption! This advanced technology overcomes the limitations of outdated liquid and powder pills by synergizing two capsules in one. It’s technology meeting efficacy without compromise.

Wow, it works!!
Where to begin, probably the best test booster I've ever used. Absolutely blown away by my results. Muscle Tech never disappoints.

Amazing Test Booster
Increased stamina, metabolism boost, and energy increase were just some of the benefits of this great product. Perfect for those with declining test production, and great for those that are just looking for that extra edge.

Excellent for older adults.
Packaging alone should tell you how serious this product is. Like any other supplements, it will only benefit you if you combine with a healthy diet and exercise. Also, being in my 40's, I can use all the extra testosterone I can get and it shows in the gym.

Great to boost Test without and can use as PCT
This was a great product to help boost natural test. There are so many on the market but it's great when you can trust great brands like Muscletech, especially at an affordable price.

One of the few test products that work! Boosts strength, energy levels, focus, and aggression in the weight room! Give it a try!
October 13, 2017
This stuff is amazing. In the one month that I was taking this stuff, combined with the new SX-7 Clear Muscle, I set all new PRs for every lift, in most cases by 20 lbs and in some 30lbs. For me, this stuff is the real deal and I could truly tell it was working.

Great Test Booster!
I was certainly needed something to boost my performance, and this has certainly helped, the Test 4K from Muscle Tech is a bit costly but overall it delivers on the promise to give you the boost that you need to work out longer and harder and to crush your goals, I really like the advance dual capsule design as well, as I feel that it assure that you are getting the full benefit of this supplement.
