I normally stay out of these kind of threads but this one is killing me.
While I agree 100% that an AI should be part of this regimen....I seriously question the advisability of starting a 34 yr old on a lifelong course of TRT drugs due to some low test levels 8 months post cycle that (I assume) have you have not attempted to deal with in other ways?
I would suggest seeking the advice of an Endo who will explore other avenues to try to restart your boys before just throwing in the towel at 34...
But that's just my opinion.
