"Anadrol was shown to be less progestagenic than even testosterone, so that has nothing to do with it. The current theory is that the A-ring is acidic due to the 2-hydroxymethylene group and therefor, oxymetholone ITSELF acts as an estrogen directly on the estrogen receptor."
"Combined with its poor androgenic effects, that makes anadrol more of an estrogen than an androgen."
"Anadrol Acts like an estrogen, or at least one of its metabolites does. regardless, aromatase is not involved, so an AI would be useless."

Big Cat in reference to taking Winny to combat Anadrol bloat from a different thread at CEM:
"First of all, it has been proven that anadrol is NOT a progestin, in fact it has less progestagenic effects than testosterone does. Its effects are most likely from anadrol acting directly on the estrogen receptor, a theory supported by both PA and Bill Llewellyn, considering it has an acidic A-ring."
"Secondly anadrol is a very weak androgen, so weak it could not be determined. Its only androgenic risk is reduction of the 2-hydroxymethylene group to DHT, which is very small and on top of that systemic, so unlikely to cause more than a few zits. In fact winstrol, also a weak androgen, was stronger than anadrol."
"Does winstrol lower water retention ? What is your evidence for this?"
"Unlike anadrol, winstrol IS a progestin and not an anti-progestin. Its a very weak progestin, so possibly of no concern, but its not only evident in its activity at the
PR but also in many of its non-genomic effects like inhibiting LAG binding."
