I dont think epi is a progestin? I smoked pot on epi and didn't have any issues with the nips even at 40mg.
Estrogen has to be present to cause prolactin side effects anyhow. With low estrogen, its harder to lactate from prolactin increase.
Im beginning to think that Epi takes different paths with different people.
I've run it twice and both times it was very very dry, killed my joints--meaning it was EXTREMELY anti-estrogenic. Dont have any clue how you could get gyno ON cycle with epistane, especially prolactin problems. NEVER heard of prolactin issues with epi on cycle.
* and if I had to guess as to why pot would cause prolactin issues, its because pot probably uses up dopamine which leaves an imbalance behind...
