Frequently Asked Questions

What is testosterone and why does it matter?

Testosterone is the hormone that makes men, men. Produced in the testicles, it’s the driving force behind muscle growth, body and facial hair, a deeper voice, and even sperm production. It’s what fuels male sexual development, especially during puberty.

But as you age, testosterone levels drop — it’s just biology. For some men, those levels drop too low. That’s called Testosterone Deficiency Syndrome (TD) or Low Testosterone (Low T). When your body doesn’t have enough testosterone, you can feel the difference, and it’s not something you have to accept.

How does oral TRT stack up against injections?

KYZATREX® is the modern man’s solution to Low T. Our TRT offers a convenient and effective alternative to testosterone replacement—without the pain that comes from injections. Same results, less hassle.

How does the ordering process work?

Fill out our quick questionnaire, get a personalized prescription and receive your discreet package right at your doorstep. That’s it. You’re on your way to feeling stronger, more confident, and more energized.

How does the consultation work? Is it virtual?

The consultation process is straightforward. Your provider will personally craft a treatment plan tailored to your specific goals. It’s like having your own personal coach—backed by a community of like-minded men. And the best part? You can do it all from the comfort of your home.

Can I combine KYZATREX® with other treatments?

Absolutely. Your provider will work with you to provide a comprehensive approach for your individual goals.

What is KYZATREX®?

KYZATREX® is a twice-daily oral capsule for testosterone replacement therapy in adult males with conditions associated with deficiency or absence of endogenous testosterone, also known as hypogonadism. It helps increase testosterone levels, addressing issues like reduced libido, fatigue, and muscle loss.

How does KYZATREX® work?

KYZATREX® is an oral testosterone replacement therapy. It is absorbed through the lymphatic system, avoiding the liver’s initial breakdown, which helps maintain stable testosterone levels.

Once in the body, KYZATREX® converts to active testosterone, which binds to receptors in muscles, bones, and other tissues, improving energy, sex drive, and muscle mass.

Testosterone works by binding to androgen receptors, which then regulate genes involved in male health and development. This process supports muscle growth, bone density, and sexual function—making KYZATREX® a powerful solution for tackling low testosterone levels.

Is KYZATREX® safe? Will it hurt my liver?

KYZATREX® is safe—for you and your liver. We’ve designed our formula to be gentle on your body while delivering powerful results.

Our oral TRT is designed for optimal absorption—bypassing your liver to prevent damage. This means you can experience the benefits of TRT without the potential liver strain associated with other forms of TRT.

What is an undecanoate?

An undecanoate is a type of chemical compound used to make testosterone last longer in the body. Specifically, testosterone undecanoate is testosterone attached to an undecanoate ester, which slows down its release into the bloodstream.

This means it provides a steady and prolonged effect, making it useful for testosterone replacement therapy. The undecanoate helps testosterone be absorbed through the lymphatic system when taken orally, avoiding rapid breakdown in the liver and maintaining stable testosterone levels.

What states is the KYZATREX® program available in?

The KYZATREX® program is available in 49 states. It’s not currently offered in New York.

How does testosterone affect both men and women?

Testosterone plays a crucial role in both men and women. In men, it drives reproductive health, supporting sperm production and maintaining sex drive, while also shaping physical traits like muscle mass, bone density, and body hair growth. It regulates fat distribution, boosts red blood cell production, and impacts mood and cognitive functions like memory and aggression.

In women, testosterone enhances sexual desire, affects menstrual cycles, and helps maintain muscle strength and bone density. It also influences fat distribution, mood, and memory, making testosterone vital for overall health in both men and women.

What are signs of Low T in men?

Low testosterone, or hypogonadism, hits hard in many areas—physically, sexually, emotionally, and mentally. Physically, it can lead to fatigue, muscle loss, weaker bones, added body fat, and urinary issues. Sexually, men may face a drop in libido, erectile dysfunction, and fewer morning erections. Emotionally and mentally, it can trigger depression, mood swings, and problems with focus and memory.

Other signs include hair loss, breast tissue development (gynecomastia), and infertility. These symptoms can seriously impact your quality of life, so it’s important to get checked if you’re experiencing any of them.

Getting Set Up was Effortless

David Saruk | Reviewed 06/23/2024

At 34 years old I had A lot of questions and fearful concerns. Their process of getting set up was effortless. Taking the test was painless and took 20 seconds. I was most impressed and thankful for the time their staff spent with me going over my results. It was educational and they took a long time explaining and answering all my questions. Also, they run very comprehensive panels. It was impressive.
