ok, this is kindof ridiculous.
People get gyno from deca which has known cross reactivity with the progesterone receptor (PR). The gymo from deca ONLY cycles can be caused by two things:
Estrogen, or nandrolone.
It is known that deca converts at a very low rate to estrogen, and this is not inhibited by blocking the aromatase enzyme, but people still get gyno even in the presence of nolvadex anti e.
So .. its probably caused by prolactin like activity at the PR.
