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.

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.

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).
