What to stop estrogen toward cycle end?

[Killzone]

I was wondering what I could take in last couple of weeks to prevent Gyno while still on the last couple of weeks of my cycle. I tend to get a little bit of gyno at the very end of my cycles and my right nipple is a tiny bit puffy and a little sore. What would be the best to take without messing up my gains the last few weeks.

Thanks

Some people swear by Proviron for the last part of a cycle.
