I went down a small rabbit hole a while back helping to track down some old CBG stock sources. Hope it helps!
I would also recommend to do reverse image searches of different CBG logos or even the strain images themselves. I found sites with stock that way that were not showing up via regular text searching.
It’s gonna be tricky to first find stock (they may say stocked but have an outdated inventory) and even then they may not ship international. Best of luck!
