It says 40iu per 1ml caninsulin. The needle is the same as in the picture U-40 1ml/40iu. I am just wanting to check I'm correct in drawing up to the 2nd notch (3rd notch from the start notch), to get 2iu. Writing this *think* I'm 99.99% correct, but I'm reallyyyyy bad at math, just want to confirm. Thanks!
