OP, humalog peaks around the 1hr mark, but it doesnt mean that it's out of your system an hour after that. humalog clears your blood in roughly 4-5hrs when injected sub-q. but don't go to sleep within 6hrs of injecting just to be on the safe side. good luck

WHY do you need to involve yourself in every god damn thread around here? especially when you are a female who has no first hand experience on the subject. stick to the diet section.
