Educational tool — not medical advice. Testosterone is a prescription medication. Your prescriber and your bloodwork set and adjust your dose — this calculator only converts a dose you already have into syringe units. It does not recommend a dose. Standard practice is to start low and titrate by labs (total/free testosterone, estradiol, hematocrit, PSA) drawn at trough. Always work with a qualified provider and follow applicable laws.
