    Étude pharmacocinétique chez l'homme : cypionate de testostérone et énanthate produisent des profils sériques quasi superposables après injection IM 250 mg, demi-vies effectives de 5 et 4,5 jours respectivement — différence cliniquement non significative.

    RCT NEJM démontrant qu'à 600 mg/sem d'énanthate (équivalent pharmacologique du cypionate), les gains de masse maigre et de force sont significatifs vs placebo, indépendants de l'entraînement.

    Guideline Endocrine Society 2018 : recommande énanthate ou cypionate IM 100-200 mg toutes les 1-2 semaines en TRT, monitoring hématocrite, PSA et œstradiol — cypionate étant l'ester de référence aux États-Unis.

    Effets de doses graduées de testostérone (25 à 600 mg/sem) sur l'érythropoïèse : l'augmentation d'hématocrite est dose-dépendante (jusqu'à +5 à 9 points à 600 mg), avec un effet âge-dépendant marqué chez les > 60 ans.
