suck it up in a syringe with an 18g needle, pull of the pin a squirt into mouth. its 200mcg so I would take it in 1/4ml incremits (50 mcg) starting at 1-2 ED and work up to your treshold over the next couple days. I find that in the 150 range is enough for me, don't overdo it or will shake like a left on a tree.
