| Evidence strength | Strong evidence | Moderate evidence |
| Evidence Score | 5/5 | 3/5 |
| User rating | 4.7 (58) | 4.7 (58) |
| Typical dose | Total PSA + digital rectal exam: before starting therapy, again after 3–6 months, then following the standard screening schedule (usually every 1–2 years, depending on age and risk factors) | There's no single universal dose — it's chosen individually to achieve a testosterone concentration in the mid-to-upper reference range for healthy young men |
| Form | Blood test (total PSA, optionally the free-to-total PSA ratio for borderline results) plus a physical digital rectal exam performed by a physician | Intramuscular/subcutaneous injections (every 1–2 weeks), transdermal gels and creams (daily), less commonly patches or subcutaneous implants |

| Time to effects | Not applicable — this entry describes a testing schedule, not a therapeutic intervention. | Libido and sexual function: 3–6 weeks. Muscle mass and strength: 3–6 months with concurrent training. Bone density: 12+ months. Mood, energy, and cognitive function: inconsistent effect, practically indistinguishable from placebo in many patients. |
| Who it's for | Men over 40 starting TRT for confirmed hypogonadism | Men with at least two confirmed, morning testosterone results below the laboratory reference range |
