it doesnt sound like an AI is needed

if your libido is down and your having ED problems...

its more likely prolactin/progesteron. from the Tren i would say

if your on proviron then that acts mild AI also.

I dont think Mast is your answer

i think Blood work is.

if anything. i would lower your doses and get blood work ASAP

or keep the doses. dont add or up anything so that you know when you get blood work that everything is the same.
