U look g2g... .5mg arimidex eod is where to start with ai. Should suffice for such a mild cycle.
Do ur research on high estrogen sides versus low estrogen sides as they can often be confused and misunderstood.
For me, water retention/bloat, puffy face, acne, oily skin, itchy/irritable/puffy nips and emotional feelings = high estrogen. Low estrogen will dry u out causing joint pain, as well as u will feel lethargic, weak and depressed. Be careful not to get paranoid and tank ur estrogen too low, it's a miserable experience.
Good luck 2 u
