I think adding it to hrt is a great idea and/or pregnenolone as well, you see i have theory that although hrt covers test there are smaller maybe less known or evens till some unknown compounds that have action in the body and that you may have a missbalance when on hrt of only test unless supplementing with also a mother hormone like pregnenolone.
long term i personally feel its a good idea, even if just dhea but i would opt for pregnenolone if only picking one.
I take M1D black because its pretty much DHEA with less conversion to estro (good thing for me) and normally also take pregnenolone daily. i havent been on the last one because i need to order more and havent bothered to be honest. but get a cheap/decent dhea or pregnenolone and see how you feel and how your blood work looks after a few weeks (could slightly raise estro of course, but i havent had an issue due to adding these personally. )
