I am TRT but do blasts obviously. Recently ran a cycle at 400mg test with Mast 400mg as well. Anyways, I generally have always ran adex but my new supplier sold ARO instead. So, I PIN my Test 2x Weekly, Monday and THURSDAY. My Aro Pills were 12.5mg I simply ran the 12.5 with each pin. So, 12.5 2x weekly. My estro is at 14! Yes, I do bloods ALOT. I am also diabetic so comes with the territory. I just wanted to see/hear other experience with aromasin not ADEX. I think I preffer it now. I just feel a bit better on it. I see people talk about the short half life so they dose ED or EOD but from what I read, it kind of work for 3-4 days hence I decided to run it every 3.5. For ME, it worked. (To good technically).
