I just went back and re-read your original post so I am not sure if someone covered this.
You are stopping your last aromatizing compound (test e) on week 14. You have it down to start PCT on 17 and run until week 22. You have it down to take aromasin at 12.5 mgs every three days until week 20.
I don’t think you will need aromasin past week 17 or 18 and that might even be pushing it. By around that time your synthetic test levels will be down around natural levels (or only slightly higher) but you will still be taking AI like you have supraphysiological levels.
Aromasin works a little different from the other AIs. It attaches to the aromatase enzyme and renders it inactive. The other AIs will eventually disconnect from the enzyme and thus the enzyme can go attack the test or other wet compound.
If you notice a real bad onset of lethargia and dry joints then that could mean you have crashed your estrogen. You know your body and this is not your first rodeo so if you have run aromasin that long under a similar time frame past your test injections and had no problems then I am waisting time typing this.
I just wanted to point that out so if you do feel really tired around week 17 or onward then you know what it might be.
