    Essai contrôlé comparatif chez patientes en cancer du sein avancé : drostanolone propionate montre une activité antitumorale palliative — base clinique unique de la molécule active, applicable à l'ester énanthate par identité du noyau actif (différence purement cinétique).

    Étude de référence : drostanolone (2α-méthyl-DHT) montre une affinité modérée au RA et une forte liaison à la SHBG — pharmacodynamique commune à l'ester propionate et à l'ester énanthate (seule la cinétique diffère).

  3. Kicman AT (2008). Pharmacology of anabolic steroids. British Journal of Pharmacology. doi: 10.1038/bjp.2008.165

    Revue de pharmacologie : l'ester énanthate du drostanolone partage la cinétique des autres esters énanthates (demi-vie ~4-5 jours) — schéma 1×/sem ou 2×/sem au lieu des injections rapprochées exigées par le propionate.

    Énoncé Endocrine Society : profil d'effets indésirables du drostanolone commun aux deux esters (propionate, énanthate) — risque androgénique cutané et capillaire, absence d'aromatisation, sans toxicité hépatique majeure (composé non-alkylé).
