    We test on animals. Mice specifically, so we take the amount that killed the mouse and multiply by 50 to get an estimate on the Lethal Dose for humans. So i guess depending on the human the true lethal dose is going to be some where between 50 times the Lethal Dose and 99 times the Lethal Dose.

    So “LD” is the amount it took to kill a mouse and 50 times that or “LD50” is the estimated lethal dose for a human

      Incorrect. LD50 is lethal dose to kill on average 50% of the time. LD99 is the dose that kills 99% of people.
