There's a new (well, returning) Euro RC vendor. The guy's called Alex and his new website is therealrc dot com. The website was down when I looked this morning. I emailed him as I was worried it had been taken down, but he got back immediately saying it's just for testing, and should be back up today. But anyway you can still order off him by email.
He used to run researchgroupnederland, which I had signed up to, hence started receiving emails about the new one. (Not sure that's exactly GDPR compliant but never mind!).
I've done a test order - 0.5g bormazolam and 2g 2DFCK. I paid by transferwise. Both arrived fine. I actually under-paid by mistake, emailed him to see how best to rectify it, and he said i could just leave it until my next order. Seems very decent!
There's a big product list, though it's lacking 4FA and etizolam. I have the full list if anyone wants to see it.
