AI’s are not lipid friendly, they raise bad cholesterol and lower the good. They increase risk of blood clots and can cause unnecessary stress on the heart. They fuse growth plates if they are still open. These are not good trade offs for zero anabolic benefit.
You can use no ai by either dialing in your test dose and letting other anabolic do the heavy lifting, or blast the hell out of test and dial in your primo/eq dose to keep estrogen in a good range for you.
Aromasin is objectively better than adex because adex does not actually kill any estrogen, it binds to it rendering it essentially useless, but all of that estrogen is still in your body. If you miss a dose, or don’t plan your frequency properly, the estrogen will become unbound and flood your system.
If you choose to run an AI, Aromasin is much more simple. It kills the estrogen, it’s gone, and it’s not coming back until you make more of it. Again, dial in your asin dose so you don’t tank it, just kill enough to bring you in range. When your levels raise again, take another 12.5mg or whatever you decide is a suitable dose for your estrogenic needs. Aromasin is also shown to raise free testosterone levels by a non negligible percentage. It was recommended for pct use once upon a time for this reason along with daa.
The alternative is to just lose fat. Extra adipose tissue brings a lot more aromatization. When you get truly lean you will need a fraction of your normal ai dose.
At one point in time I needed low dose aromasin for 300mg test. Currently I can run 500+ Sust with zero estrogen management at a lower body fat.
