They are made by 2 different companies. The mix is slightly different, as the numbers tell you. Humalog has lispro protamine insulin as the 75. and lispro as the 25. Novolog has insulin aspart protamine as the 70 and insulin aspart as the 30. The biggest difference is the amounts, because they are both long acting and short acting insulins.
I don't know, that's why I'm asking the question.
