You can buy 200mg pure anhydrous caffeine pills at Walmart for like $5. It's abundant and as safe as coffee if you don't go nuts. The max daily recommended dose is 400mg, anything past that could cause harm

What I had in mind is more like this 25kg bucket. That's enough to kill about 2,000 people, which is actually a lot fewer people than I would have guessed before I looked up the LD50.

I've never actually seen caffeine in a bucket myself, but I worked in a lab once that had a big plastic jar of it.

Isn't the LD 50 just over a gram?

[–] ArbitraryValue 1 points 1 month ago (1 children)

What I read was that it's about 200mg per kg, so for a 70kg human that works out to 14 grams. That actually sounds remarkably high (14 grams is a lot). Did I mess up somewhere?

I didn't bother to look it up, that was just my random vague understanding. I'd trust your numbers over mine.
