HbA1c — Peptide Glossary | RetatrutideCompare

A blood-test marker that reflects average blood glucose over the past two to three months, reported as a percentage. Used to diagnose diabetes (≥6.5%) and to track how much a glucose-lowering peptide is actually working. Most GLP-1 trials report HbA1c reductions as a primary or secondary endpoint.
