Formebolone (INN, BAN) (brand names Esiclene, Hubernol, Metanor), also known (confusingly) as formyldienolone, as well as 2-formyl-11α-hydroxy-17α-methyl-δ¹-testosterone, is an orally active anabolic-androgenic steroid (AAS) described as an anticatabolic and anabolic drug that is or has been marketed in Spain and Italy. As an AAS, it shows some anabolic activity, though it is inferior to testosterone in terms of potency, but is said to have virtually no androgenic activity. Formebolone counteracts the catabolic effects (control of nitrogen balance) of potent glucocorticoids like dexamethasone phosphate. A close analogue, roxibolone (and its long-acting ester variant decylroxibolone), shows similar antiglucocorticoid activity to formebolone but, in contrast, is devoid of activity as an AAS.
