Dissolving NBOMe HCLs.. lend some insight for the sake of safety?

[SabbathViper]

My 250ul micro-pipette will be here tomorrow, and my 20mg 25C-NBOMe HCL is already here. Unfortunately it was shipped in a baggie rather than a nice glass vial, so I am worried that some residue will account for product loss overall when measured on the mg scale. Anyways!

I plan to dissolve the 20mg into 20ml of water in a 1:1 ratio, then use the micro-pipette to perfectly measure out 250ul/ug doses for placement either in microvials (for dosing intranasal) or on blotters for buccal/sublingual.

My fear is this: when dissolving the NBOMe into water, and siphoning it out - how do I know that it isn't concentrated more in particular areas of the liquid than others? For example, how do I know that one 250ul sample from the solution isn't more potent than the next? Obviously constant and vigorous stirring will keep things moving, but is it safe to assume that it is fairly evenly distributed in a 1:1 ratio in the water?

I want to be a safe, accurate, and methodical as possible for my sake and that of my friends.

Yes, having a few mgs difference from bought amount and weighed amount is quite scary with a substance of that potency

When the powder is completely dissolved, swirl the vial around for a bit, that should do the trick. Once the stuff is evenly distributed in the liquid it won't spontaneously accumulate at the top or something. That's the great thing with solutions.
You don't need to constantly stir because the molecules move by themselves at room temperature, keeping a constant concentration throughout the liquid (as long as nothing evaporates).
Just dissolve the stuff in your solvent (20% ethanol in water is preferred, that kills microbes and makes it last longer; disadvantage is you need to watch evaporation over time), swirl it around, perhaps pipette a few times up and down until you're sure there are no layers of different concentration anymore (if you ever diluted vodka slowly, you know what I mean) and you're good to go. Of course, giving it a good swirl before you take a dose out won't hurt

Good luck and stay safe!
