Fasting glucose improved within weeks and my HbA1c barely moved for three months, which I now understand and did not at the time.
The narrow version of the question is why A1C lags the way it does, and what to look at in the meantime if you want to know sooner.
Happy to be told the question itself is wrong.

My labs after 3 months on glycaemic control: A1C 5.3%, fasting glucose 83 mg/dL, fasting insulin 4 uIU/mL. My endo says these are "textbook perfect."
For context, my baseline A1C was 8.1% and fasting glucose was 128 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) | 113 | 99 | 93 | 83 |
| Insulin (fasting) | 19 | 13 | 9 | 6 |
| HOMA-IR | 5.5 | 2.9 | 2.1 | 1.2 |
| Uric Acid | 7.6 | 6.3 | 6.0 | 4.9 |
The insulin resistance improvement (HOMA-IR) is what my endo focuses on most. Going from 5.5 to near 1.0 is a metabolic transformation.

This is my experience too, for whatever a second data point is worth. Posting only so the count is not one.
From the other side of the consultation, briefly.
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 = 5.7 (insulin resistant) → Current = 1.5 (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.
