I never said your dose was excessive. I said uncontrolled e2 will cause those exact symptoms.
Many, many men on 200mg/week of test c require an aromatase inhibitor to control their e2. Many men require changing their dosing schedule to prevent side effects -- I'm fine without an AI on 200 if I inject 3 days per week. If I inject every 3.5 days, I need an AI.
Sustanon carries the same side effect profile as test cyp. Esters do NOT change the mechanism of action of the hormone, or their side effect profile. Esterization controls the rate of release into the body, allowing for longer or shorter injection intervals. Sustanon is a combination of four esters intended to balance long injection intervals with minimizing peaks and valleys in testosterone values.
