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 This advanced technology overcomes the limitations of outdated liquid and powder pills by synergizing two capsules in one.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.

Vitamin D
This is nothing more than an overpriced vitamin D supplement. The derivative ingredients do not increase testosterone, strength, muscle growth, performance, etc.

Power, Recovery, Strength
Product was overall excellent, just what you want and need from a test booster. It is in the higher price range but it does provide great results. If you can buy it you should invest in it.

Really good stuff
I was a little uncertain about this product at first but decided to give it a go and I'm happy I did! While not an awe shocking amount, it did help me gain more muscle that I'm sure I wouldn't have without it (I gained more, quicker than I was averaging before). I only wish the supply was a little bigger but otherwise, I'm a happy customer!

Wow worth the money

Energy all day.
This supplement does give you energy, but not a whole lot at once more less it keeps you going all day. It's best used during a cut. I would recommend this to anyone starting a new routine and be sure to cycle it. For cutting purposes use this with the SX 7 Hydroxycut and the clear muscle and you will see a decent gain in muscle mass and strength with that stack.

Pair this With Clear Muscle and LOOKOUT! Awesome!
I paired this product with Muscletech's Revolution Clear Muscle and was shocked by the results! I never knew I could add weight to my lifts as much as I did and as quick as I did. While taking this, I felt stronger and had more energy in the gym. There was never a day where I had a bad workout! Amazing product!
