Short answer first, then the reasoning. 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.

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.

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

One order arrived in nine days, one was held at the border for a fortnight, and one came back with a seizure notice.

Same pattern here, and in the same order. Posting only so the count is not one.

From the other side of the consultation, briefly.

My experience ordering cross-border ordering internationally: I've ordered from a UK pharmacy. Customs can be hit or miss.

Shipping time: 7-14 days
Customs clearance: smooth, no issues
Quality: Janoshik tested at 99.1% purity

International ordering adds complexity but can save 60-80% compared to US prices. Research your country's import laws first.
