    Revue de pharmacologie : la chaîne ester propionate (C3) est la plus courte des esters de testostérone disponibles, induisant une libération rapide depuis le tissu adipeux et une demi-vie plasmatique courte (~2 jours) — pic sérique précoce, fluctuations marquées sans schéma EOD.

    RCT NEJM démontrant qu'à 600 mg/sem de testostérone (énanthate), les gains de masse maigre et de force sont significatifs vs placebo, indépendants de l'entraînement — courbe dose-réponse anabolique transposable au propionate à exposition totale équivalente.

    RCT dose-réponse (25 à 600 mg/sem de testostérone, axe HPT supprimé) : gains de masse maigre et de force dose-dépendants — courbe applicable à tout ester de testostérone une fois normalisée sur l'exposition cumulée hebdomadaire.
