6-marker hormone panel same day. First TRT injection in Busan. English protocol letter for home-country GP to continue treatment.
Testosterone deficiency requires total T <300 ng/dL on two morning fasting draws plus symptoms. Dr. Hwang runs a 6-marker panel, screens TRT contraindications, then initiates treatment. Nebido (every 10–14 weeks) is preferred for foreign patients — first injection in Busan, subsequent injections at home GP with our English protocol letter.
| Marker | Normal Range |
|---|---|
| Total Testosterone | 300–1,000 ng/dL |
| Free Testosterone | >65 pg/mL |
| LH + FSH | LH 1.5–9.3 IU/L |
| Prolactin | <20 ng/mL |
| PSA | <3.0 ng/mL (age-adjusted) |
| Hematocrit | 38.3–48.6% |
IM injection every 10–14 weeks. First injection at Busan Men's Health; subsequent injections at home GP using our English protocol letter. Stable levels, minimal peak-trough fluctuation.
Every 2–3 weeks. Self-injection training included. More flexible but requires more frequent administration.
