    Étude PK chez le cheval (LC-MS/MS, 64 jours de suivi) : boldenone undécylénate 1,1 mg/kg IM montre une demi-vie d'élimination médiane de 123 heures (~5 jours pour la boldenone libre après hydrolyse) et un résiduel détectable jusqu'à plusieurs semaines — corpus PK de référence pour l'ester undécylénate.

    Étude de référence sur l'affinité relative au récepteur androgène : la boldenone (1-déhydrotestostérone) montre un profil intermédiaire entre testostérone et nandrolone, avec une affinité musculaire élevée et une aromatisation modeste — ratio anabolique/androgénique 100/50.

    Revue de pharmacologie : la boldenone s'aromatise à environ 50 % du taux de la testostérone et stimule l'érythropoïèse de manière marquée (augmentation de l'hématocrite) — augmente l'appétit (effet utilisé en zootechnie sous le nom Equipoise).

    Énoncé Endocrine Society : la boldenone (Equipoise) est un AAS vétérinaire détourné vers l'usage humain ; profil d'effets indésirables typique des aromatisables (gynécomastie possible, érythrocytose marquée) avec une dimension de qualité produit accrue par l'origine vétérinaire.
