Adamax Blood Work Labs Check Before After — Comparison Table

This table shows how key biomarkers typically shift from baseline to 8–12 weeks post-protocol for common peptide categories, along with professional assessment criteria. IGF-1 (ng/mL) Age-adjusted normal (e.g., 150–250 for age 30–40) 40–90% elevation from base

  • This table shows how key biomarkers typically shift from baseline to 8–12 weeks post-protocol for common peptide categories, along with professional assessment criteria.
  • IGF-1 (ng/mL)
  • Age-adjusted normal (e.g., 150–250 for age 30–40)
  • 40–90% elevation from baseline
  • >400 ng/mL warrants dose reduction
  • Elevation confirms GH secretagogue efficacy; exceeding 400 ng/mL increases risk without added benefit
  • Fasting Glucose (mg/dL)
  • 70–99 (normal)
  • Should remain <100
  • → or slight ↑
  • ≥100 mg/dL indicates impaired fasting glucose
  • GH can transiently raise glucose; sustained elevation requires protocol adjustment
  • ALT/AST (U/L)
  • <40 / <35 (normal)
  • Should remain within 10% of baseline
  • ALT >60 or AST >50 requires investigation
  • Transient elevation during dose escalation is common; sustained elevation suggests hepatic stress
  • Total Testosterone (ng/dL, males)
  • 300–1000 (normal)
  • Should remain stable or increase slightly
  • → or ↑
  • <300 ng/dL indicates suppression
  • Some peptides suppress endogenous production; significant drop requires intervention
  • SHBG (nmol/L)
  • 10–57 (males), 18–114 (females)
  • Should remain stable
  • Significant deviation alters free hormone availability
  • Changes in SHBG affect bioavailable testosterone/estradiol even if total levels are stable
  • Hemoglobin A1c (%)
  • <5.7 (normal)
  • Should remain <5.7
  • ≥5.7% indicates prediabetes
  • Long-term glucose control marker; more reliable than single fasting glucose tests
