    Étude pharmacologique princeps caractérisant l'ester hexahydrobenzylcarbonate de trenbolone (Parabolan) : libération encore plus étirée que l'énanthate (demi-vie ~14 jours) tout en partageant la même molécule active 19-nor non-aromatisable.

  2. Yarrow JF, Conover CF, McCoy SC, et al. (2011). 17β-Hydroxyestra-4,9,11-trien-3-one (trenbolone) exhibits tissue selective anabolic activity: effects on muscle, bone, adiposity, hemoglobin, and prostate. American Journal of Physiology - Endocrinology and Metabolism. doi: 10.1152/ajpendo.00440.2010

    Étude préclinique : la molécule active (17β-OH-trien-3-one) est identique pour les trois esters (acétate, énanthate, hexahydrobenzylcarbonate) — l'ester ne modifie que la cinétique, pas le ratio anabolique/androgénique ni la non-aromatisation.

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

    Revue de pharmacologie : Parabolan (trenbolone hexahydrobenzylcarbonate, THBC) était la formulation officielle (Negma) ; son ester très long et l'absence de production légale actuelle expliquent la rareté sur le marché parallèle et la prédominance de l'acétate ou de l'énanthate.

    Énoncé Endocrine Society : profil de toxicité de la trenbolone, indépendant de l'ester (acétate, énanthate, hexahydrobenzylcarbonate) — lipides effondrés, hypertension, néphrotoxicité potentielle, effets neuropsychiatriques (insomnies, agressivité, hyperhidrose).
