A1C went from 7.4 to 5.6 over nine months and my prescriber was more interested in the fasting insulin, which I did not expect.
Because it is glucose-dependent, this class carries a low intrinsic hypoglycaemia risk on its own — the risk arrives when it is combined with insulin or a sulfonylurea, which usually need reducing.
What I am after is why A1C lags the way it does, and what to look at in the meantime if you want to know sooner.
Numbers rather than impressions, if you have them.

My labs after 9 months on glycaemic control: A1C 5.6%, fasting glucose 81 mg/dL, fasting insulin 4 uIU/mL. My endo says these are "textbook perfect."
For context, my baseline A1C was 7.7% and fasting glucose was 116 mg/dL. The improvement has been dramatic and consistent.

Complete metabolic panel trending on glycaemic control — sharing because comprehensive data helps everyone:
| Test | Baseline | Month 3 | Month 6 | Month 12 |
|---|---|---|---|---|
| Glucose (fasting) | 128 | 102 | 92 | 86 |
| Insulin (fasting) | 24 | 16 | 8 | 6 |
| HOMA-IR | 4.5 | 2.9 | 2.0 | 1.2 |
| Uric Acid | 7.6 | 6.8 | 5.9 | 4.9 |
The insulin resistance improvement (HOMA-IR) is what my endo focuses on most. Going from 4.5 to near 1.0 is a metabolic transformation.

Adding a me-too, because a thread of one person's experience is not much use. Posting only so the count is not one.
Clinical perspective, offered as context rather than as advice.
Insulin sensitivity test (HOMA-IR) on glycaemic control — arguably the most important metabolic marker most people aren't tracking:
HOMA-IR = (fasting insulin × fasting glucose) ÷ 405
My numbers: Baseline HOMA-IR = 4.8 (insulin resistant) → Current = 1.2 (insulin sensitive)
Anything above 2.0 indicates insulin resistance. The goal is below 1.5. GLP-1 agonists address the root metabolic dysfunction, not just the symptoms. This is why they work so much better than calorie restriction alone.
