Not all insulins are the same. My guess is that this insulin is glargine (https://en.wikipedia.org/wiki/Insulin_glargine https://en.wikipedia.org/wiki/Insulin_glargine) which just came off of patent in 2015. Glargine is a synthetic long-acting form of insulin that gives allows absorption without peaks, which is much better than previous types of long-acting insulins.
