Blood Markers to Monitor When Using Supraphysiological Testosterone, Other PEDs, or Growth Hormone

Marker Standard Reference Range Optimal for Skin Health Concerning Levels Critical Levels Key Interpretation Notes (PED Users)
MMP Activation
hs-CRP 0–3.0 mg/L < 0.5 mg/L 1.0–3.0 mg/L > 3.0 mg/L Systemic inflammation; triggers MMP surge. Elevated during blasts sacrifices skin quality.
GGT 0–40 U/L (varies by lab) < 20 U/L 20–40 U/L > 40 U/L Oxidative stress; glutathione depletion. Predicts MMP activation even if ALT/AST normal.
Uric Acid 3.5–7.2 mg/dL (varies by gender/lab) 4.0–5.5 mg/dL 5.5–7.0 mg/dL > 7.0 mg/dL Oxidative damage from cell turnover. Levels >6.5 mg/dL suggest burden exceeds capacity.
LDH 140–280 U/L < 200 U/L 240–280 U/L > 280 U/L Tissue breakdown; confirms oxidative/inflammatory damage. Test after 48–72 hours rest.
Glycation
HbA1c 4.0–5.6% 4.2–5.0% 5.0–5.6% > 5.6% Long-term glycation (2–3 months). GH/insulin users: Even small rises accelerate skin aging.
Serum Fructosamine 200–285 μmol/L < 250 μmol/L 250–285 μmol/L > 285 μmol/L Short-term glycation (2–3 weeks). Catches spikes HbA1c misses during blasts/diet shifts.
Glycated Albumin (GA) 11–16% 11–13.5% 13.5–16% > 16% Specific short-term glycation (2 weeks). Useful for altered red cell turnover in PED users.
Fasting Glucose 70–99 mg/dL 75–85 mg/dL 86–99 mg/dL > 100 mg/dL Daily snapshot; persistent highs indicate constant sugar exposure damaging skin.
Lipid Peroxidation
Oxidized LDL (Ox-LDL) < 60 U/L < 50 U/L 50–70 U/L > 70 U/L Direct lipid peroxidation; precursor to ALEs. Request separately if not in standard panel.
Triglyceride/HDL Ratio Varies (calculated) < 1.5 1.5–3.0 > 3.0 Ectopic fat predictor; indicates insulin resistance promoting peroxidation.
ALT/AST Ratio ALT <40 U/L, AST <40 U/L ALT <25 U/L, AST similar/higher ALT 25–50 U/L (ALT > AST) ALT >50 U/L (AST normal) Suggests NAFLD/ectopic fat if ALT high. Muscle-related if post-training.
VLDL 5–40 mg/dL < 20 mg/dL 20–40 mg/dL > 40 mg/dL Ectopic fat transport; high levels shunt fat to wrong tissues, including skin.
Anion Gap (from CMP) 5–12 mEq/L 7–10 mEq/L 10–12 mEq/L > 12 mEq/L Metabolic stress/acidosis; indicates mitochondrial ROS during cutting cycles.
BUN/Creatinine Ratio 6:1 to 22:1 10:1 to 15:1 15–20:1 > 20:1 Catabolic stress; subtle sign of high mitochondrial ROS in fat oxidation states.
