I'm having sore nipples now 4 weeks into my testosterone cycle and can you guys please tell me if my gynecomastia symptoms will go away on their own or if I need to take something to cure it?
No, gyno will not just leave on its own - you will have to do something with it. Do what Mexico told here as soon as possible, and you still may get rid of it. Make sure you use an AI on cycle - always, and from the first day of the cycle.
