Prami works well...and quickly.
Your nips are sore...this is what leads the average person to believe that it would be estrogen related gyno symptoms. Most always with prolactin symptoms you are seeing some kind of discharge with the nipples, and at a Deca dose of 250mg I wouldn't think you'd see that kind of issue, with most people at least, but I could be wrong.
This being said, I have run Tren + NPP at the same time, once with Prami, and once without. I actually didn't notice any difference in terms of prolactin sides. Androgens are what get me with the estrogen related gyno symptoms, every time. That's why I stick with Letro. Never have to worry about it.
