I'm glad that you've got this mindset here, when it comes to blotter I recently applied around half a gram of MDMB-4en-PINACA which can be fatal~800mcg. To lay it accurately, I used sheets that were 2.5"x5" in a dish that exact size with squared off edges, so there was no space left uncovered. The other thing that made it work was using a solvent that fully dissolved it, 200 proof ethanol for this specific compound (it also evaporated quickly). I did all of this with full PPE, and then sterilized every single surface that was touched, and acidified then basified the shit out of the baggie with lye, to destroy any residuals so that a racoon won't go through my trash and accidentally eat MDMB-4en-PINACA in an unknown amount, god help the hypothetical raccoon.
I similarly am a vigilante at destroying toxic mushrooms in public places, I think it's just part of being a pro-social person who exists in a dense enough society to where people walk place-to-place, to think something like "Man, I should beat these Amanita phalloides fruiting bodies into unrecognizable pieces, so that a small child, dog, or squirrel might not hypothetically take a toxic bite out of it".
Sorry for the rant, bupropion just sunk in. I think you made a very smart decision here, personally.
That stuff sounds pretty much as potent as CF to be honest

. Ultra potency is only dangerous if you mishandle or don't know the dose (the acidifying / basifying is a great idea to chemically decompose and render residues inactive, clever)
Since we're here talking blotter, might be helpful to go through the process for others, if just for educational purposes.
Usually what I would like to do is take whatever sample of paper that I'm going to be using and take a 10x10 square, weigh it on a milligram scale, submerge it in the 90.9% alcohol solution for 60 seconds, and weigh it again to get the difference in weight to see exactly how much liquid the paper absorbs.
Then you take the difference between the beginning weight and the ending weight and that is the weight of the solvent that you're using that soaks into the paper.
That number can be used to get the calculation so that you can dial the strength of the blotters properly.
So if 10x10 sheet soaks up about let's say a gram (It's not actually a gram. You have to weigh this every batch of paper because different batches of paper can absorb solvents at different rates, this is why we have to *time* the submersion and keep the submersion time consistent through the whole batch if making a bunch of 100 lots to keep the process consistent)
But anyway say it soaks up about a gram of fluid and you want the botters to be100 mcg a pop.
The calculation will be as follows;
1 gram into mg = 1000 mg solvent soaks into the paper.
To get 100 mcg per unit (~10 mg of fluid per blotter - [10X100=1000 mg or 1 gram)
So for the compound, you need 10 mg per gram of fluid to make a concentration of 100 mcg per unit paper. It is easier to make batches in bulk, so one may want to use say 50 mg in 5 grams of solvent, should get you at least 3-4 properly submerged blotts with some leftover soak fluid.
Just a handy FYI for anyone wanting to lay some blotts, It's all ratio calculations. If you don't trust your math, get it checked by someone you trust! One wrong 0 can make a great time into a bad time in a hurry.
Lay tinfoil down on your work surface so it can be discarded after chemically wiping the area to make sure no residue harms anyone or any creature, do the same with your tools that are getting put away, you'll have leftover fluid likely as it's best to have enough to properly submerge the blotts in, and dry them laying flat on a wire cookie rack so the fluid doesn't all sink to one side giving you a dangerously "hot" 10 strip on the bottom side. And try to make sure the 100 lots don't crinkle and make high / low spots if possible.
Then, once the solvent is completely evaporated, (if you've got your stuff verified and tested) start with maybe a quarter blot, give it enough time to soak in and hit, then adjust dose as needed. Also have a trip sitter and any drugs that can help bring you or whoever out of an OD if it were to occur.
This should help keep some party people safe. Oh and **label your leftover fluid with concentration per mg or find the volume calculation if you're gonna use it dropwise, and label any leftover powder with a big warning deadly danger label so nobody goes and digs around in your stuff thinking they found a bag of blow and tries a 1000 dose bump by accident**
