Oxymetholone ('Anadrol', 'A-bombs') is a potent 17α-methylated oral DHT-derived steroid used clinically for anaemia and wasting and recreationally for extreme mass and strength. It causes strong water retention and marked hepatic strain, and despite not aromatising it produces pronounced oestrogen-like effects through a poorly understood mechanism.

It produces rapid gains in mass and strength, driven substantially by water retention, and aromatises to a methylated oestrogen. Its speed made it a bodybuilding and strength-sport staple despite pronounced hepatic strain and oestrogenic side effects.
