When the body's own levels are no longer sufficient
Testosterone replacement therapy (TRT) is a medically indicated treatment used in men diagnosed with low testosterone (hypogonadism). The goal is to restore hormonal balance, alleviate symptoms such as loss of libido, lethargy, or muscle loss, and stabilize physical and mental health in the long term.
When is TRT useful?
A TRT is an option if
- Symptoms of testosterone deficiency (e.g. loss of libido or mood, decreased performance) are present.
- Blood tests, ideally taken over two morning measurements , should show clear deficiency values (< 12.1 nmol/l).
- Conditions such as sleep apnea, prostate cancer, and high hematocrit were ruled out.
- A medically supervised evaluation by a professional hormone panel has been carried out.
The TRT-Check from Adon Health is ideal at this stage: It measures testosterone, SHBG, LH, albumin, and PSA. A medical review can then follow via video call, perfect for those who want to collect their own test results and have them medically assessed.
How does a TRT (Transactional Reception Therapy) process work?
- Diagnostics via the TRT check or in a doctor's setting
- Treatment decision : Depot injection (e.g., testosterone enanthate), gel, or other forms
- Plan an individual starting dose (e.g., 125–250 mg testosterone enanthate every 1–2 weeks)
- Regular check-ups : blood tests (hormones, PSA, hematocrit), monitoring of treatment success
- Goal : To raise testosterone levels to the upper end of the physiological range, alleviate symptoms, and improve quality of life.
Mechanisms of action & effects
TRT works on several levels:
- Increased libido and possible improvement in erectile function
- Muscle strength and mass increase, fat tissue decreases.
- Energy levels improve, mental clarity returns.
- Mood can stabilize.
- Metabolism can improve, especially insulin sensitivity and liver function.
The effect is individual, but usually noticeable within a few weeks (mood, libido) and lasting for months (body composition, sleep quality).
Risks & side effects of TRT
Like any hormone therapy, TRT carries potential risks, but these are well controlled when used under medical supervision:
- Elevated hematocrit (risk of thrombosis)
- Estrogen increase during aromatization (breast tenderness, mood swings)
- Skin side effects, such as acne or hair loss (in case of sensitivity to DHT)
- Inhibition of the body's own testosterone production (LH repression)
- Reduced sperm production (relevant when trying to conceive)
- Potential effects on the prostate (at high doses or with existing cancer)
👩⚕️ Crucially: For safe TRT, regular blood tests, PSA testing, hematocrit monitoring and medical supervision are necessary; this is exactly what Adon Health offers through the TRT Check and medical follow-up care.

Conclusion
Testosterone replacement therapy is not a lifestyle hack, but a medically supervised intervention in your hormonal system. With proper indication, implementation, and monitoring, it can significantly improve quality of life.
If you are suffering from symptoms such as loss of libido, fatigue, muscle loss or sleep problems, it is recommended to start with a TRT check from Adon Health , combined with further blog content and explanatory podcasts to make informed decisions.
