HbA1c
Also known as Glycated Haemoglobin · Haemoglobin A1c
A blood marker of average glucose over the prior 3 months — the standard metric for diabetes screening and GH-axis protocol safety.
Definition
HbA1c reports the percentage of haemoglobin molecules with attached glucose, reflecting average blood glucose across the prior 10–12 weeks. Under 5.7% is normal; 5.7–6.4% is prediabetic; 6.5% and above meets the diabetic threshold. Meto requires HbA1c under 6.5% before starting P2, P4 or Tesamorelin; members on GLP-1 therapy typically see HbA1c drop 1–1.5 points over six months.
Reference Range: Under 5.7% normal; 5.7–6.4% prediabetic; 6.5%+ diabetic threshold

Fasting Glucose
Blood glucose measured after an 8-hour fast — the simplest metabolic-safety screen before any GH-axis or GLP-1 protocol.
BiomarkerFasting Insulin
Insulin measured after an 8-hour fast — a sensitive early marker of insulin resistance.
Clinical ConceptMetabolic Syndrome
A cluster of five conditions — central obesity, hypertension, dyslipidaemia, hyperglycaemia, low HDL — that together multiply cardiovascular risk.
