Hey Fellas, just had some questions on the need for AI's. I will soon be doing a 12 week Test C only cycle of 500mg pinned twice a week. I'm already on TRT by my endo so I'm told that there isn't a need for pct since I'll already know what my steady baselines will be. one of my questions would be do I need to run an AI during this cycle to keep the E2 levels in check? My other question would be, if so which one and what dosage? I'm 6'2" 165lbs and 38 y/o. I will have pre-cycle bloods done before starting and also plan to do mid-cycle bloods as well.
