    Étude de référence sur l'affinité relative au récepteur androgène : le methénolone (dérivé 1-méthyl-DHT) montre une affinité musculaire modérée et une absence d'aromatisation — ratio anabolique/androgénique 88/44 conférant un profil « doux » utilisé en sèche et chez la femme.

    Revue de pharmacologie : le methénolone énanthate (Primobolan Depot) partage la cinétique des esters énanthate (demi-vie ~5 jours), avec absence d'aromatisation et activité minimale au niveau de la 5α-réductase — composé doux historiquement utilisé en oncologie pédiatrique et en sèche compétition.

    Énoncé Endocrine Society : le primobolan figure parmi les composés DHT-dérivés non-aromatisables et non-alkylés, avec un profil de toxicité limité à dose modérée mais une qualité produit à vérifier (marché parallèle souvent contrefait).
