Protocols

One doctor. Three solutions.

Your ZENKAI doctor sees the full picture. TRT, ED, and hair loss often share underlying causes — we treat them together.

⚡
TRT — Testosterone
Male Hormone Replacement Therapy
Low testosterone causes fatigue, lower libido, fat gain, loss of muscle mass, and trouble concentrating. TRT restores your hormone levels to the optimal range, with regular monitoring through lab work.

Beta Program · Pre-launch

The first ZENKAI Men patients.

Before public launch, a small group tested the service. Below: beta feedback and the clinical evidence backing the TRT protocol.

★★★★★
Beta Program

"Hormone panel ordered through the app, urologist reviewed in 24h. Started the protocol that same week. The monthly portal follow-up is what sold me — no more re-booking the same consultation every 3 months."

★★★★★
Beta Program

Clinical Evidence

"Testosterone replacement therapy in men with hypogonadism is associated with improvements in libido, energy and body composition, with normalization of serum testosterone when adjusted by a specialist physician."

Beta program testimonials from the pre-launch phase. Individual results may vary based on adherence, prescribed dose and clinical factors. TRT, tadalafil and finasteride must be used under medical supervision.

Frequently Asked Questions

Men's health, answered.

How do I know if I need TRT? ▾
The most common symptoms of low testosterone are chronic fatigue, low libido, difficulty building muscle, abdominal fat gain, irritability, trouble concentrating, and an overall drop in performance. Your doctor will order a blood test to confirm your testosterone levels before issuing any prescription.
Is compounded tadalafil effective? ▾
Yes. The active ingredient is the same as Cialis (the brand). The compounded version is produced at an ANVISA-authorized pharmacy at a dose individualized by your doctor. Many patients report better efficacy with a personalized dose compared to standard commercial doses.
Does TRT cause infertility? ▾
TRT can reduce sperm production with long-term use. If you plan to have children, discuss it with your ZENKAI doctor before starting. There are alternative protocols (such as HCG) that preserve fertility while restoring testosterone.
Do I need lab work before starting? ▾
For TRT, yes — the doctor needs a hormone panel (total and free testosterone, LH, FSH, complete blood count) before prescribing. If you don't have recent results, you can order them during the process. For ED and hair, lab work is generally not required.
