Read all of Nelson's stickied threads on this subject. They have certainly helped me. My understanding is that he recommends a TOTAL T / E2 ratio of 14 - 20. I've followed this advice and allowed my E2 levels to creep up to between 50 - 60 at ~1000 TT, and feel much better than when I shot for 25-35 E2. My protocol is:
Testosterone Cypionate 90mg every 3.5 days
HCG 350iu on injection day
Anastrazole .125mg on injection day.
I'm considering the daily injection protocol that is recommended by many users on this site to see if I could eliminate the AI entirely, but I'm hesitant to fix what really isn't broke.
