Your E2 is going to be elevated alot. Are you running an AI along side it? That was a long cycle for short esters. Did you take HCG to keep your HPTA going?
Personally I would have ran it at 50/50/50/25/25. Clomid increase E2 and causes spikes. It is also liver toxic. I always practice using as...
Personally I think 2.5mg of letro is abit much. I would have preferred aromasin. But as some one said it could be from prolactin. The Adex should be able to take care of it. If your going to do letrozole I'd start abit lower. Maybe .5 or 1mg a day. 2.5 is rough.
I'm speaking from experience...
