dissolves almost instantly... the percentage for error, if you have the right amounts of solvent and solute materials(everclear and the amt), is really only in the actual mixing of it. Wear gloves, don't breathe it in, and try not to let it contact your skin or eyes, because then you could get an unknown dose transdermally or transmucosally.

Anyway, i think the stuff isn't worth it. To me it feels dirty, speedy, and not very euphoric. It made me feel like crap and the trip wasn't very good.
Also, since the dose is so low,just a few milligrams difference could make your dose too much or too little, so just be careful how much you take.
