second time I've ordered this product off these guys to the UK. first time was a litre second time was 5 litres. the second order did take 3 weeks but nothing to do with the seller it was the reliable postal system. I got it in the end so all is good. i can safely say absolutely amazing quality methylamine (mono) solution 40% in water so ready to go with most experiments one might be doing with this stuff. perfect for making mephedrone from 2b4m or making methamphetamine from p2p (BMK) - These guys are the Don and I am very pleased. TY constantylicious777 and Godspeed to you all
