Glycated Haemoglobin

Glucose Metabolism marker

HbA1c

Glycated Haemoglobin

Category: Glucose Metabolism
Unit: %

Average blood sugar over 2-3 months. Best marker for long-term glucose control.

PED Notes

GH use can worsen HbA1c over time, indicating insulin resistance. More reliable than single glucose readings as it reflects 2-3 months average. High haematocrit from AAS can affect accuracy of some HbA1c assays. Target <5.5% for optimal metabolic health.

Supplements:

  • Berberine -- 500mg 2-3x/day
  • Alpha-Lipoic Acid (ALA) -- 300-600mg/day

Lifestyle:

  • Low-glycaemic diet
  • Regular cardio and strength training
  • If HbA1c trending upward on GH, consider dose reduction
