I have to admit that I used a somewhat slap-dash method of Googling for "Compounding Pharmacy Raleigh" and calling a lot of different pharmacies looking for one where the pharmacist had any clue what I was looking for. I'm fairly sure the one I finally found is the best one in my area.
But, if I were looking now I might try this search tool from the "PCCA" (Profession Compounding Centers of America).
www.pccarx.com/contact-us/find-a-compounder/They are somewhere between a trade organization and a wholesale supplier but their search tool found 25 compounding pharmacies within 50 miles of my house, including the one I used to use when I was using trimix.
If you are looking for a mail-order compounder (and they are frequently less expensive) then perhaps some other member can make a recommendation. I looked at some old threads and found one that several members seemed happy with but, when I Googled for them, I found that the FDA had shut them down last year.
