Kesell 10-Pack 5ml (0.17oz, 1.35dram) Glass Vials with Screw Caps | Borosilicate Glass, Clear, Graduated, Labeled | Small Vials for Samples

I use a little 5mL glass vial. You can put it on your scale and weigh your MGM-15 and citric acid out inside of it, and when it’s time to dose add h20 with water bottle or from any water source, and shake the shit out of it to protonate MGM-15 before drinking. They’re super convenient and can go right in your pocket. If you need to dose discretely just use the bathroom and there is your water source also. Something like this: https://a.co/d/084TulFK
