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
