Read two books recently written by diabetic men and both hated human insulin,now this is what im starting on from tomorrow so a bit worrying so anyone on human and if so how do you find it. I can see the profiles are peaky and will make insulin control more difficult and am just hoping it works to bring down my rising bgs and hba1c
Many of the people who dislike the Human Insulins started on Porcine or Bovine and had trouble switching over. There are equally large numbers of us who have never used them and are fine with Human Analogue insulin.
As for the term "peaky", it's rather dependent on what you are put on.
NPH Isophane is the old intermediate action insulin, and yes, that was "peaky".
Levemir (Detemir), Lantus (Glargine) and Tresiba (Degludec) are much less peaky, and the fast acting insulins, well, they are by design "Peaky" as they are supposed to be fast acting.
I don't think I'd say that the use of MDI or these insulins makes insulin control "more difficult" than using animal insulins. They have different characteristics from each other, and in all fairness, Insulin control without knowledge of how the insulin works is always going to be more difficult.
The Novomix 30/70 that you have been using so far is already Human Insulin. As long as you are educated in how to use the various insulins, I don't think you'll find one or the other more difficult.
