Fun you mention it! I tested out the Humalog myself and benchmarked it up against the NovoRapid which I still use today. I found that for me personally the Humalog had onset and peak like 30 minutes later than then NovoRapid. And as you also remark, the tail effect was also showing 2-3 hours after, while the NovoRapid for me burns out in max one hour. So for me the Novorapid is easier to dose with for the type of food I like and eat the most. And maybe also the best rapid weapon in our arsenal to take down an incoming chocolate bar missile?
