Long term insulin

The lantus/glargine I got last week was dated 09/2024 and expires 08/2027. (It's my emergency supply for if my pump breaks so I get 5 or so cartridges a year.)

But I have a similar query with my humalog. My new supplies are regularly expiring in about 6 months and I'm not that happy about it. Having said that, I'm in New Zealand which is typically at the end of a long supply chain.

When I lived in the UK (and Australia) my insulin always had a least a year before expiry.
