Just gonna throw this out there since it isn’t ever talked about on most forums.
I aromatize like crazy, and generally need a lot of anti-e in any test I run. It took me years to figure this out because of the common advice that is thrown around on boards across the internet of “have it on hand but you probably won’t need much on 500mg test.”
I don’t respond well to Aromasin, and I’ve posted elsewhere over the years and found there are others like me. I took it for my first 3 cycles, and had high estro sides such as oily skin, acne, bloat, puffy nipples, achey man-tits, limp dick half the time, etc.
I switched to Arimidex and its much easier to control, and I know when it works. I take .5mg/day with 500mg test E, .25mg/day with 250mg. Even on 25mg a day of Aromasin at 250mg I had high estro sides, but never full-blown gyno.
So my advice is make the switch.
