lI thought same thing about sensitive nipples.My base prolactin level is araound 20. So i think deca is still little efective on prolactin. High prolactin is also supressing libido a little, so it protects me from crazy testo's sex drive

I will take AI, and check again estro. How about Nolvadex. Do i need it on cycle?
By the way i read from some articles that hyperprolactinaemia can cause gyno. Here also i found a possible mechanism:
"Hyperprolactinemia is not believed to play a direct role in gynecomastia, although pro- lactin receptors have recently been demon- strated in gynecomastia tissue.8 Most patients with gynecomastia have normal serum pro- lactin levels.9 Moreover, not all patients with hyperprolactinemia have gynecomastia. Elevated prolactin levels may, however, sup- press gonadotropin release, producing sec- ondary hypogonadism, which then contributes to the development of gynecomastia."
