Formebolone also known (confusingly) as formyldienolone, as well as 2-formyl-11α-hydroxy-17α-methyl-δ1-testosterone, is an orally bioavailable anabolic-androgenic steroid (AAS) described as an anticatabolic and anabolic drug. 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.
