Re: To clarify the term Lethal Dose...
It's not like you give the lab animals medical treatment when measuring the LD50.
Also, I'd presume that noone (except possibly Mengele and his North Korean equivalents, but they don't publish their results) has actually done studies into the LD50 of caffeine in humans, so any numbers are gonna be an extrapolation from animal studies combined with case studies of human intoxications.
I'd guess that most caffeine poisonings anywhere near this range is suicide attempts,and typically that would be caffeine pills and not pure powder, which makes it hard to get close to this dose.
