Most guys obsess over total testosterone.
And while total T matters, it’s actually free testosterone that determines how you look, feel, and perform.
Free T is the active form.
It’s the testosterone your body can actually use.
Here’s the problem…
A protein called SHBG (Sex Hormone Binding Globulin) is quietly stealing your testosterone. It binds to it, locks it up, and makes it completely unavailable to your body, regardless of how much you’re producing.
And a lot of common things drive SHBG through the roof.
- Cutting drives it up
- Aging drives it up
- Alcohol drives it up
Every man is aging, and most are dealing with at least one of the other two on top of it, which means a significant chunk of their testosterone is locked up and doing absolutely nothing.
This is why boron is one of the most important and most overlooked supplements for men.

Boron does two things that nothing else does as effectively.
- It lowers SHBG levels directly.
- It reduces SHBG’s binding affinity, meaning even the SHBG that remains has a weaker grip on your testosterone.
The research[1] shows this combination produces a 28.3% increase in free testosterone.

And the benefits go well beyond free testosterone.
- Anti-inflammatory: Studies show that just one week of boron supplementation cut key inflammation markers by up to 50%.
- Vitamin D and bone health: Boron works hand in hand with Vitamin D, extending how long D3 stays active in your body and making it significantly more effective.
- Cognition: Improves cognitive performance, brain function, and short-term memory.
- Libido: Supports libido through its effects on free testosterone and inflammation, two of the biggest drivers of male sexual health.
And all of this comes from the same landmark study on boron referenced above. The free testosterone increase, the drop in inflammation markers, and the SHBG reduction.
It’s one of the reasons Mojo works as well as it does.

Boron is inside every serving, working alongside Tongkat Ali, Zinc, Magnesium, and D3+K2 to not just raise your testosterone production but make sure the testosterone you’re producing is actually free and available to your body.
Total T is what your body is producing, and Free T is what your body can actually use.
There’s a big difference between the two
