Started my Test/NPP/Mast cycle on the 17th of February. Went on vacation for 5 days, and during those 5 days my nips started exploding!! Holy crap, lol never had estro sides set in so fast. Got home, and immediately took 25 mg of exemestane, which oddly enough usually mitigates any gyno related sides for me. Was just really surprised at how fast I got little ball bearing lumps, puffy, and sensitive nipples. A lesson learned on even taking 5 days off of support supplements gentlemen.
