Dissolve it in food grade propylene glycol(which can be found on amazon.com). I use 2mgs per 1 mL of P.G.
Well, you add the powder to the liquid, or liquid to the powder, and you stir, sometimes with gentle heating, until you can't see the powder any more.
If you don't know how to dissolve powder into a liquid (never made instant coffee before?), then you shouldn't be messing with benzos.
More to the point: for 99% of the benzos and their analogs, just eat the stuff. Obviously don't eat the whole 100mg in one go... that's why you make a solution, so it's easy to measure a dose.
