SJA, Are you using ATD as HRT? I am, at 1 RXT every 10 days. My thinking was to use a small dose that would keep E lowered but not eliminated and at least moderatley up my T level and to use a small dose to prevent the AR inhibiting action that some have speculated ATD might have.
I've been doing this for 64 days now. My subjective impression, based on testicular size, muscle hardness and emotional response,is that it's working well. I'm way overdue for a blood test, I'll get one next month.
People have been using enzyme inhibitors like Adex and Letro because steroidals haven't been avaliable until now and my reading on these compounds support what D has said, that there's a definite rebound possibility there, and less so with ATD's parent compound, Exemestane. ATD is not exactly Exe, but I'll assume it shares similar characteristics.
If I do another wet cycle, and I probably won't, I think I'll bump the ATD dose to 1 every 3 to 5 days to keep the extra E being produced by the gear in check, then drop back to the 1:10 at PCT and ongoing along with the standard inverse pyramid dosing of Nolva.
Watcha think, D?
