Currently on 750 test e a week, noticed some gyno forming early on and hopped right on letro ramping up to 2.5mg for a week then back down to .25mg, which I h e been on since so I didn't get an estrogen rebound. Just got some aromasin in today from man power, 12.5mg. Would I be ok to stop taking the letro and run one cap of the aromasin in its place so I don't get an estrogen rebound? Gonna run it up untill I start PCT in 8 more weeks.
