I've got about a quarter inch of pill residue at the bottom of my 60 mL bottle. I poured it into a 100 mL graduated cylinder and then left it there for a day and poured it back into the 60 mL bottle but there's still a tiny bit of residue at the bottom. Wondering if anyone has a nifty trick for getting rid of it. A centrifuge is the right way to go but I'm not going to take that step, I don't think I can get one for less than like 50 bucks. Plus it would be something I would buy only for this. Seems wasteful.

1mg pills, which is part of the problem. So I'll ask the doc for 5mg pills. But I added in some caffeine pills and those left residue too. So I'll probably buy some liquid caffeine drops, if that's a thing. The base I'm starting with is minoxidil in propylene glycol.
