You want the same amount per pound of person that you would give per pound of horse. The little plunger is calibrated in 50 lb increments.
Usual size of the tube is 1500 lb of horse. Enough for 7.5 doses for a 200 lb person.
If you show serious symptoms you are supposed to triple the dose according to the Front line doctors. From .2mg per kg to .6 mg per kg. I think this gets overlooked a lot.
