Good advice from Sekio and Survived Abortion, there's not much more to say on the subject. This is absolutely not a substance you can even consider eyeballing. If for some reason you do not want to buy a scale and conduct liquid measurement or get a
microgram scale, then you should look at buying this on blotter, from a source you would really trust, and sample 1/4 to 1/2 of a blotter to begin with in case the dosing isn't correct.
If you have a milligram scale, you can use it to weigh up a portion of powder and then further divide that by
liquid measurement. If you don't yet have a scale, check out
this thread on scales to help you decide on which one to purchase before you continue.
Since your question has been answered I'm going to close this.
Coolio, this is a harm reduction forum. Please don't give out such reckless advice. In the interest of peoples safety I've removed your post.
Even all of the powder in a single batch can appear to be of different consistencies, with three doses weighed out at 5mg each, all three could appear anywhere from ~1-10mg+ in size. The human eye has even been known to make bigger mistakes than that with eyeballing, being as much as 20-30mg+ out, though this usually applies more when dealing with larger amounts.
The human eye can't discern between 0.5mg, 1mg, 1.5mg or 2mg, and when some people find even 500-600ug a significantly potent trip with this chemical (and almost all do if they snort it as the thread starter plans!) then you have no room for even 0.5mg error, nevermind 1.5mg..
This isn't just about "Oh he's not taking 20x the active dose so he's unlikely to die", but also about the fact that too much will likely result in an uncomfortable and unpleasant trip. Alongside that, these are new chemicals and there have been hospitalisations and deaths already that may be linked to them, some of which occurred at abnormally low doses, so just taking a small amount more than expected could potentially be dangerous - and in fact, this is true with any drug so potent since some people are especially sensitive.
Anyway, your question was answered. If you have anything more to ask, head on over to the
Liquid Measurment,
Scale Thread or the
25C-NBOMe Thread. Hope this helps!
