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.
Not looking for reassurance. Looking for the part I have got wrong.

Patient selection optimization for glycaemic control: emerging predictive biomarkers for GLP-1 agonist response include:
| Biomarker | Association | Evidence Level |
|---|---|---|
| Baseline BMI | Higher BMI → greater absolute weight loss | Strong |
| Fasting insulin | Higher insulin → better response | Moderate |
| GLP1R gene variants | rs6923761 → variable response | Preliminary |
| Baseline hsCRP | Higher CRP → greater CV benefit | Moderate |
| Early weight loss (4 wk) | ≥3% at 4 wks → strong predictor of ≥10% at 68 wks | Strong |
The 4-week early responder criterion is the most clinically actionable: if you haven't lost ≥3% by week 4 at a therapeutic dose, discuss optimization strategies with your provider.

My labs after 3 months on glycaemic control: A1C 6.0%, fasting glucose 75 mg/dL, fasting insulin 8 uIU/mL. My endo says these are "textbook perfect."
For context, my baseline A1C was 6.5% and fasting glucose was 120 mg/dL. The improvement has been dramatic and consistent.

This is my experience too, for whatever a second data point is worth.
Adding the clinical framing, because it changes how the question reads.
PCOS success story with glycaemic control: as someone with polycystic ovary syndrome, this medication has been transformative beyond weight loss.
After 10 months: periods became regular for the first time in years, testosterone levels normalized, acne cleared significantly, and — unexpectedly — I got pregnant naturally after 4 years of trying.
GLP-1 agonists address the insulin resistance at the root of PCOS. For PCOS patients, this isn't "just" a weight loss drug — it's treating our underlying metabolic dysfunction.
