yes more test... the +200 jump u made will = more estrogen from ur body aromatizing even with anastrozole .....the AI ionly cuts out a % of the body estrogen not put it to normal range. you can adjust once or twice in a cycle. just don't roller coaster your hormone levels. u can run the 900 if you want n see how you feel although you won't know for 2 weeks. if ur tren sides increase then go back down to 700. imo, 200mg is a mild difference so you may or may not feel or see a difference.
