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.
I would rather have one careful answer than five confident ones.

Glycemic variability as the key metric for glycaemic control success: my coefficient of variation (CV) on CGM dropped from 36% to 18%. Target is <36%, with <30% being ideal.
Why this matters more than average glucose: large glucose swings cause oxidative stress, endothelial damage, and promote advanced glycation end-products (AGEs). A flat glucose line at 95 mg/dL is metabolically healthier than oscillating between 60 and 160, even if the average is the same.

My labs after 3 months on glycaemic control: A1C 5.4%, fasting glucose 79 mg/dL, fasting insulin 8 uIU/mL. My endo says these are "textbook perfect."
For context, my baseline A1C was 7.3% and fasting glucose was 114 mg/dL. The improvement has been dramatic and consistent.

Same pattern here, and in the same order.

PCOS success story with glycaemic control: as someone with polycystic ovary syndrome, this medication has been transformative beyond weight loss.
After 11 months: periods became regular for the first time in a decade, testosterone levels normalized, acne cleared significantly, and — unexpectedly — my fertility specialist is optimistic about future conception.
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.
