I copied this from another site, just thought i'd share it:
Some androl users have reported gyno from its use but this is unlikely to be a result of anadrol (which doesn't convert to estrogen, nor DHT, nor can it stimulate the progesterone receptor). Users of Anadrol who experience gynocomastia (the of breast tissue by males) have probably developed this condition as a result of the concurrent use of another steroid along with their Anadrol.
i always thought this drug was the worst for gyno!
