Been on cycle for about 8 weeks now, recently upped my test to 600mg a week after that started to experience itchy and puffy nipples , was running arimidex 1 mg every 3 days but doesn’t seem to be working anymore . Got letro and nolva . Can you recommend the dosage for each to proceed and how long before I see a change and how long before I should cut back on AI’s all together?
