Comprehensive TRT Options Tailored to You

We understand that every patient is unique. That’s why we offer a full spectrum of FDA-approved TRT methods to fit your specific needs, preferences, and lifestyle. While we provide traditional options like injections, gels, and patches, we place special emphasis on modern, convenient, and effective therapies like Kyzatrex® oral capsules and BioTE® pellets.

For those seeking the ease of a pill, Kyzatrex® offers a modern, FDA-approved oral testosterone option.

What it is

Kyzatrex® is a capsule containing testosterone undecanoate, a specific form of testosterone designed for oral administration.

How it works

Taken twice daily with meals, Kyzatrex® utilizes a unique absorption pathway (through the lymphatic system) that minimizes the potential liver stress associated with older, now discontinued, oral testosterone formulations.

Key Benefits

  • Needle-Free & Application-Free: The ultimate convenience of simply taking a pill.
  • No Transference Risk: Unlike gels or creams, there’s no risk of transferring medication to partners, children, or pets through skin contact.
  • Discreet & Portable: Easy to manage and ideal for travel.
  • FDA-Approved: Meets rigorous standards for safety and efficacy.

BioTE Medical provides a method of hormone therapy using bioidentical hormone pellets. As a Certified BioTE Provider, we offer this popular TRT approach.

What it is

Tiny, custom-compounded pellets containing bioidentical testosterone are inserted just under the skin (usually in the hip area) during a simple in-office procedure.

How it works

The pellets slowly and consistently release testosterone directly into your bloodstream over several months (typically 3-6 months).

Key Benefits

  • Convenience: Requires only a few brief visits per year, eliminating the need for frequent injections.
  • Steady Hormone Levels: Helping to avoid the hormonal peaks and valleys associated with some other methods.
  • Personalized Dosing: Pellets are custom-dosed based on your specific lab results and needs.

A cost-effective method involving intramuscular injections, typically weekly or bi-weekly (in-office or self-administered).

Applied daily to the skin, providing steady absorption. Requires care to avoid skin-to-skin transference.

Worn on the skin and changed daily. Less commonly used now due to potential for skin irritation.

TRT requires ongoing medical supervision. We develop a personalized treatment plan based on your diagnosis and goals. We conduct regular follow-up visits and blood tests to ensure your testosterone levels are optimized safely, monitor for potential side effects, and adjust your therapy as needed.

If you suspect you have low testosterone, don’t wait to seek help. Reclaiming your energy, focus, and vitality is possible.

What Patients Are Saying

  • Anthony

    Dr. Sun is one of the few doctors who really listens to you and will always take the time to address your concerns and answer questions and is highly knowledgeable. Very highly recommended.

  • Jesus M

    Dr. Sun was recommended by a friend of mine, and I’m glad he was. He is not only obviously knowledgeable, he’s personable and as dedicated to providing the best experience as any man can hope. Himself and his Assistant, Deja, made me feel comfortable throughout the entire process. I recently contacted him about a specimen count as I was overseas and wasn’t available after the short healing time. An entire year since the procedure Dr. Sun is still as attentive to my needs as the day I met him. Thank you so much, Doc!

  • Guoliang Wang

    Dr. Sun was referred to me by my daughter who is a MD. I consulted Dr. Sun for my health remotely and was very impressed by his eagerness to treat patients and by his intelligence and deep domain knowledge in the field. He was very polite and asked detailed questions to really understand my situation. Then he explained to me patiently in full detail about the different medications, procedures/surgical options, and each of their advantages and side effects. I was so happy consulting with Dr. Sun as he helped me understand my health situation in a deeper and broader aspect. I highly recommend Dr. Sun.

  • Ty Turkett

    Never heard of Peyronie’s disease at 55 before speaking to Dr Sun but after him giving me an explanation and best direction for correction I felt much more comfortable moving forward with surgery. I am happy to say he did a fantastic job of correcting curvature and explaining after care stretching. I highly recommend Dr Andrew Sun as your urologist as he will continue to be mine moving forward.

  • James B. Bobo

    I was referred to Dr. Sun by a friend of mine, after reading his Bio I chose to have a consult with him. Dr. Sun is extremely intelligent and knowledgeable on many things when it comes down to male health. I chose Dr. Sun to do my NSV & was amazed by how little pain there was. I felt no pain during or after the procedure. Dr. Sun was gentle and accurate with every motion. He also possesses a very outgoing and comedic personality! Which made the entire procedure a breeze. Highly Recommend Dr. Sun!

  • Gehrig Saldana

    I gladly submit my personal referral for my excellent urologist, Andrew Y. Sun, MD. Dr. Sun has been my urologist for almost a year to date. I’m 71 years young, & noticed over the past few years I had to wake up too many times to use the restroom disrupting my sleep along with having ED creep up on me as I aged to my present age. My primary physician referred me to Dr. Sun & I’m glad he did! Dr. Sun’s care for my prostrate (multiple trips to restroom at night) issue & my ED issue are now resolved to a point where I sleep much better at night. Top that off with my ED issue now pretty much in my rear view mirror. In short, I feel like I’m living the life of a 50 year old dude! Thank you Dr. Sun! Gehrig Saldana
