Earlier quoted context omitted.
Insulin is hyper regulated in the US. There is no free market for insulin.
Is it significantly cheaper in other jurisdictions? Like Canada?
In general all medications are the most expensive in the US, often by a lot. For two main reasons:
1. All other countries are to some extent "free riding" on the US market, and refusing to pay full price.
2. The FDA is doesn't approve a lot of things. So many cheap foreign medications are illegal to import. I heard that many forms of insulin are in this group.
