How can you tell if gyno symptoms are being caused by estrogen or prolactin without running blood tests? Nips are getting a little tender. I ran out of adex so I've been running a low dose of letro 1-2x a week. I have caber from a RC but stopped taking it. I'm not sure if its legit but I may need to get back on it. I'm just not sure which is causing the tenderness.
