HOMA-IR tracking on GLP-1 — anyone have experience?

Taking the question as asked, rather than the general version of it. HbA1c reflects roughly three months of average glycaemia weighted toward the most recent weeks, which is why repeating it at six weeks tells you very little. The improvement on this class comes from two directions — direct glucose-dependent insulin secretion and glucagon suppression, plus the indirect effect of weight loss on insulin sensitivity — and the second continues after the first has plateaued.

I would rather be corrected than agreed with, if it comes to it.

Agreed, with the caveat that HbA1c is unreliable in anaemia, haemoglobinopathies and recent blood loss, all of which are commoner than people assume. If it disagrees with fasting glucose or a CGM, that is worth chasing.

Living somewhere the domestic route does not exist, which makes most of the advice on this board inapplicable to me.

This matches mine closely enough to be worth saying so out loud.

From the other side of the consultation, briefly.

International shipping tracking for cross-border ordering orders: my experience with customs in the US when ordering from overseas:

Required FDA import alert review, delayed 10 days.

Tips: always include a copy of your prescription, declare medication properly on customs forms, keep quantities reasonable (personal use = 3 month supply max), and use a vendor who has experience shipping to your country.
