I'm thinking of switching back to HCG Mono from Test/hcg/ai because of various reasons(cost, more natural, mood, easier to maintain). I was a very good responder to HCG when I first did it. My doc will have me doing HCG at 500 IU 2x a week for a total of 1000 IU/week. My question is on the arimidex dosage. What is a good starting point for this? The last time I did HCG Mono, I was doing 1mg twice a week, and I felt like my E2 was going pretty low. I have heard some guys on Mono do 0.5mg twice a week. Any advice on where to start?
