Good question. For guys on HRT, there is no need to do PCT. I would just wait about 10 days, 2 wks and then go back to your HRT dose. During this waiting period, before you start HRT back up, I would continue on arom. BTW, good for you in .6ml cyp every 2 wks is working, but this is quite a low dose. If your test levels are optimal, in the upper end of normal and you feel normal, good, but I would get your labs done to make sure things are right. A common dose for HRT is more like 1cc every 7-10 days. So just throwing it out there.
