The best gyno protocol is raloxifene. Period. 120mgs/day week 1, 60mgs/day thereafter.
You should get blood work, find out whats going on. If e2 is elevated and needs managing mange it with an ai such as exemestane. Then treat the gyno with raloxifene and be patient. It takes time. There is no reason to crush your e2 levels with letro to treat gyno. It is unhealthy and uncomfortable as hell and totally unnecessary.
