I'm very prone to gyno and especially puffy nips (enlarged areolas) and on my current cycle I didn't take an anti e and not surprisingly it happened again.
I've found that adex run at .5 or even .25mg ED is the best way to go but you must keep up with the dosage as adex takes 7days of continuous use to stabilize plasma levels in your system and for ANY effects to be seen.. I would recommend starting that now and don't stop as you might not notice any changes for some time its a subtle and gradual difference..

I'm planning on running letro which I've heard does a good job of blocking estradiol in a shorter amount of time, but I guess I'll find out! keep us updated on what you try and how it works!

if your running deca/tren, or something similar start taking high levels of b6 for now and order something more effective like prami or caber. im sensitive to 19nor compounds myself. the b6 helped but i just stopped taking the deca to prevent it from getting worse, it was a while ago. you can also run letro, but read up on it on using it for gyno, you havnt told us which compounds your running. read up on b6 for prolactin/progesterone gyno and same for letro/prami/caber. wont take much research to narrow it down. letro actually got rid of a good size lump under my left nip, and softened/reduced the bigger one under my right. letro is very very potent so like i said research, you dont want 0 estrogen, just lower it

I had the same thing happen last summer running Sust with proviron. I made the mistake of not using a proper anti-e. Nolva seemed to help me out. After the cycle and pct it seemed to slowly go away. Its completely gone now.

I ran prop/NPP for my last cycle and used Prami instead of caber. It worked well for me to prevent prolactin gyno and really upped my sex drive, to the point of being annoying.

What compounds have you run that might have caused your gyno?
