Could it really be the estrogen? Its only about 200mg test prop a week and tren or masteron doesn't aromatize into estrogen?
Before I could run 300mg test E with no problems at all?
masteron functions as an anti-e so with that low test it shouldn't be estrogen that's mainly causing it. though, all 3 female hormones play a role in gyno, together, so when someone get's gyno it's not
just the estrogen, though both estrogen and progesterone need to be present for gyno formation. tren and deca both breath down into metabolites that bind strongly to the progesterone receptor, which is why people get gyno on them so frequently even though they don't convert to estrogen in great abundance like test or dbol.
so letro works for some people who get gyno on tren because letro not only stops the conversion of 99% of estrogen, it also down regulates progesterone receptors, so it's a an extremely effectual way of halting gyno and reversing it. for prolactin gyno, it doesn't seem to help much, and with prolactin gyno things like nolva/clomid will actually make it worse because they have been documented to cause prolactonemia and both seem to increase prolactin output (at least from personal experience it seems that way).
so letro and cabergoline should be your main tools in ridding or stopping gyno.
