First, by no means is it going to be given out in bulk nor to random people or in anyway misrepresented for profit. I only mentioned blotters because of the idea of using the liquid measurement system since a microgram scale is too expensive to even be mentioned.
OK you thought of blotters when you started this thread, but you thought of liquid measurement first? Well use that then, only liquid measurement and leave any sort of carrier away. No eye droppers, no candy, no sugarcubes you make in bulk.
Read the whole liquid measurement thread, then understand that you can use an alcohol solution like vodka, you can put 100 mg (weigh it yourself!!! do not trust the vendor on it!!!) in maybe 200 ml of vodka to get 0.5 mg per ml. Then get food colorant, like blue. Color the solution a toxic blue color. Put it in a glass container and secure a big label on it with a skull symbol and TOXIC: bromo-dragonfly in huge letters. Store it away somewhere nobody can reach it.
If you have tried the compound on your own and learn to use it correctly and how you react to doses and then want to take it at a party do not take multiple doses with you that could allow you to ingest them from the confusion of tripping effects, make sure you keep that vial with the single dose close to you.
Yes blotters exist with this stuff on it, its bad enough that there are cases of mistaken identity. I will not let there be promotion of more of this business going on.
What extra information do you seek, that can be believed to be used for good? Let us know so that it may be answered - other than that just read again what I am posting here about using liquid measurement and using precautions. Such are ways to take care with it and keep it away from others, think again about ideas of sharing.
I am not really interested in what you say your intentions are because someone with intent to distribute would say the same things and an argument why you would need blotters for yourself does not make sense.
I have things like DOI in pure form and store them that way put away safely until a day comes that I want to try it and then I will use liquid measurement for it like I decribed for BrDfly.
