* Get the blotters/microdots lab tested so you know dosage per blotter, then volumetric dosing. This is relatively easy/accesible although not very convenient.
* If access to crystal and equipment is possible, you can just weight it. Obviously this is rarely a possibility and LSD crystal needs to be handled with care.
People suggesting volumetric dosing at home are simply clueless, "100ug" blotters are almost never ~100ug.
I actually have Fadiman's book but didn't get to the part of micro dosing - was more interested in the full trips guidance, but I remember being very intrigued by micro dosing.
Lab tested you say... not convenient as in I can't just go to a lab and tell them "hey I need to be trippin so can you check these blotters"?
Dissolve in alcohol, avoid water like others suggested. You can't calculate micrograms if the blotter dosage is unknown, lab testing is needed for that.
> if it's in liquid form, I'm guessing it's already in some volumetric dosing
Yes, just take a smaller dose then.

Here in my country I can... this kind of services are available for free in some European countries.
Energy Control in Spain provides this to foreigners for a relatively small fee. You can contact them at: international AT energycontrol.org
You're right, but it's probably much easier than you think[1].
You can also send anything into ecstasydata[2] and it will be tested a posted to the site. Unfortunately under US law they can't tell you purity or dosage, but can at least tell you if it's legit.

However, yes, the distribution per piece may be off.
Is that considering "tedious" nowadays?
