| Typical dose | Typical doses are practically identical for both esters: 50–100 mg weekly, 100–200 mg every two weeks, or an equivalent dose split into more frequent, smaller injections — which we cover in more depth in our entry on testosterone injection frequency. | Not applicable — this piece describes the full diagnostic pathway preceding TRT, not a drug dosing schedule |
| Form | An oily solution for intramuscular or subcutaneous injection; concentration most often 200 mg/mL, though 100 mg/mL or 250 mg/mL occur depending on the manufacturer — it's the dose and concentration, not the ester itself, that determine the injection volume. | Blood tests: total testosterone (2x morning), free testosterone, SHBG, LH, FSH, prolactin, estradiol, complete blood count with hematocrit, PSA, lipid panel, fasting glucose or HbA1c, liver function tests, TSH; plus a digital rectal exam and an ADAM/AMS symptom questionnaire |

| Time to effects | Not applicable in a clinical sense — this is a comparison entry, not a description of an intervention. As for the time to reach a stable concentration after switching esters at the same dose and frequency, both preparations reach their target, repeatable profile in a similar timeframe, usually after 3–5 half-lives — practically indistinguishable between enanthate and cypionate. | Not applicable — a diagnostic pathway preceding any possible start of therapy, usually taking several weeks. |
| Who it's for | Patients on TRT wondering whether switching esters will change their well-being or therapy outcomes | Men with symptoms suggesting testosterone deficiency (reduced libido, erectile dysfunction, chronic fatigue, loss of muscle mass) considering TRT |
