| User rating | 4.5 (58) | 4.7 (58) |
| Typical dose | A fasting lipid panel before starting TRT, then a check at 3–6 months from the start of treatment, and after that usually once every 6–12 months on stable therapy | 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 | A blood draw after a 9–12 hour fast: total cholesterol, LDL, HDL, triglycerides | Intramuscular/subcutaneous injections (every 1–2 weeks), transdermal gels and creams (daily), less commonly patches or subcutaneous implants |

| Monthly cost | — | — |
| Time to effects | Most changes in the lipid profile stabilize within the first 3–6 months of therapy; further significant shifts after that point are less typical with stable dosing. | 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 starting or continuing TRT who want to know what to expect on a follow-up lipid panel | Men with at least two confirmed, morning testosterone results below the laboratory reference range |
