I would like to update you guys that I was able to get pharmaceutical grade DCA from a pharmacy in Aurora, Ontario. The pharmacist ordered it from a canadian pharmaceutical company specialized in compounding prescription chemicals.
It is Hollandview Pharmacy. Phone is 905 726 4400. When I asked the pharmacist about DCA he took the time to phone the pharmaceutical componding suppliers to search for it. He phoned me back when he found it and again when he received it. I believe he still might have some supply. He told me that this powder has the tendency to absorb humidity from the air so I should keep the container tightly closed.
I bought DCA in capsule formfromthem for my cousin they compound it according to the dose we need it's very very pure pharmaceutical grade we bought DCA before from different places but unfortunately not pure It's worth to give them a call they also deliver it to USA
