Sorry to hear that bro, I have had some bad gyno and nothing sucks more. This is all from my own experience on successfully reducing gyno, take it as you please.
Evaluate: is it only puffy gyno (soft almost swelling of the nipple) or has a lump formed (tissue behind nipple that is hard and rubbery)?
- Puffy: reducing estrogen with Letro will likely make the puffiness reside in about 2-4 weeks. 1.5 mg EOD is a good starting point. Taper dose down slowly over 2-3 weeks to avoid rebound. Note at 2.5 mg EOD your estrogen will crash and you will feel like shit but in some cases it is necessary.
- Lump: reducing estrogen with Letro will stop the growth but you will need to starve the gland of estrogen to reduce the amount of tissue that has formed. This means higher doses closer to 2.5mg EOD. I would also recommend using a low dose SERM such as Nolva (20mg) or Ralox (30mg). A lot of guys will disagree with using Letro along with a SERM but in my experience it is the most effective, especially Ralox. The SERM will bind with the gland to ensure that no further estrogen is binding. Again tapper Letro to avoid rebound and run SERM 2-3 weeks past last dose of Letro.
Just my 2 cents, typed this really quick of the top of my head sorry if its simplistic.
