Have a question for anyone who would be willing to help me with it. I'm on 150mg/week of test cyp for HRT, and started an epistane cycle about a week a go, so far I have been running it at 30, was going to go to 40 this week. This past week I noticed a small knot on the top edge of my nipple, but my nipples aren't sore, or lactating. They are puffy, but I'm at around 14% body fat, so it's hard to truly tell. If it was an early symptom of gyno, would the knot or nipples be sore? If you over feel your nipples, can that make a knot? I was taking erase prior to starting the epi, but I stopped due to epi acting like an AI. If this is a gyno symptom would an OTC AI be strong enough(6oxo,formeron,formesurg e), or would I need a RC grade AI? Appreciate anyone who would help me here!
