Testosterone is often seen as the ultimate marker of strength, energy, and performance—but here’s the catch: having high Total Testosterone (Total T) doesn’t always mean your body is getting what it needs.
Most testosterone in your bloodstream is tied up by proteins that make it inactive. That’s why what really matters isn’t just how much testosterone you have, it’s how much is actually available for use. This is where Free Testosterone (Free T) comes in. It’s the active form of testosterone responsible for muscle growth, metabolism, stamina, and sexual health—but only a small percentage of your Total T is actually free.
So how do you increase Free T and keep your body performing at its peak? And how does KYZATREX® deliver these results? Let’s break it down!
Testosterone Markers
Testosterone plays a critical role in muscle growth, energy, and overall well-being, but not all testosterone in your body is available for use. The key distinction lies in how testosterone is classified—some forms are readily available to the body, while others are bound to proteins and inactive.Here’s a breakdown of the categories that define testosterone levels:
- Total Testosterone: The total amount of testosterone in your bloodstream, including both active (free) and inactive (bound) testosterone. While this number is a general indicator of testosterone levels, it doesn’t tell the full story of what your body can actually use.
- Free Testosterone: The unbound form of testosterone, making up only 1-3% of Total T. Free T is the biologically active portion available for muscle development, energy production, and sexual health.
- Bound Testosterone: The majority of testosterone in the body is bound to proteins, which affects whether it can be used.
- SHBG-Bound Testosterone: Testosterone that is bound to Sex Hormone Binding Globulin (SHBG). SHBG tightly binds testosterone, making it inactive and unavailable to the body. Higher SHBG levels can significantly lower Free T and limit its effectiveness.
- Albumin-Bound Testosterone: While also bound, Albumin-Bound Testosterone is loosely attached and can be converted back into an active form, making it more accessible than SHBG-bound T.
- Bioavailable Testosterone: The sum of Free T and Albumin-Bound T. This is the testosterone that the body can actually use for key functions like muscle growth, energy production, and metabolism.
Why Free Testosterone Matters
While Total T provides a broad picture of your testosterone levels, Free T is what truly drives performance, strength, and well-being. Even if your Total T levels appear normal, high SHBG can reduce Free T, leading to fatigue, muscle loss, and diminished libido.
Maintaining optimal Free T levels supports:
✔ Strength & Muscle Development – Low levels of Free T can lead to muscle loss and increased fat storage, making it harder to maintain a strong, lean physique.
✔ Stamina & Energy – Free T helps regulate red blood cell production and oxygen delivery, boosting endurance, reducing fatigue, and keeping energy levels stable throughout the day.
✔ Sexual Health & Performance – Testosterone plays a key role in libido, erectile function, and overall confidence. Low Free T can result in decreased sex drive and reduced performance.
How KYZATREX® Supports Free Testosterone
Not all testosterone replacement therapies work the same way. While many treatments focus on raising Total T levels, they don’t always address the real issue—low Free T. That’s where KYZATREX® stands out.- Lowers SHBG – High levels of SHBG can trap testosterone, making it unavailable for the body to use. KYZATREX® bypasses the liver and has been shown to reduce SHBG by 30%, ensuring more testosterone stays active and bioavailable.
- Doubles Free T Levels – In a 6-month clinical study, KYZATREX® doubled Free T levels by Day 90, helping men experience real improvements in strength, energy, and sexual health.
- Convenient Oral Treatment – Unlike injections or patches, KYZATREX® is an FDA-approved oral testosterone therapy, offering steady, effective hormone delivery without the hassle of frequent injections or messy topical applications.
While KYZATREX® helps increase Free T levels by reducing SHBG and improving testosterone availability, your daily habits play a crucial role in how effectively your body utilizes that testosterone. Here’s how you can support your Free T naturally:
✔ Strength Training & Resistance Workouts – Lifting weights and engaging in compound movements like squats and deadlifts stimulates testosterone production and helps maintain lean muscle mass.
✔ Proper Nutrition – A diet rich in healthy fats (like avocados and nuts), lean proteins, and key minerals (such as zinc and magnesium) supports hormonal balance and muscle growth.
✔ Reducing Stress & Prioritizing Sleep – Chronic stress and poor sleep increase cortisol levels, which can negatively impact testosterone production. Getting 7-9 hours of quality sleep and managing stress through relaxation techniques or mindfulness can help keep Free T levels optimized.
✔ Staying Active – While intense workouts are important, daily movement matters too. Activities like walking, stretching, and staying generally active support circulation, metabolism, and hormone regulation.
When combined with KYZATREX®, these lifestyle habits enhance the effectiveness of your TRT, helping you achieve better strength, stamina, and overall well-being.
Is KYZATREX® Right for You?
If you’re struggling with low energy, muscle loss, or decreased libido, your Free Testosterone levels could be the missing link. Total T alone doesn’t tell the full story—it’s Free T that determines how much testosterone your body can actually use.
KYZATREX® is designed to optimize Free T by reducing SHBG and making more testosterone available where it matters most. If you’re ready to take the next step toward better performance, increased energy, and long-term health, Thrive’s medical experts are here to help.
