🩸 Bloodwork Biomarkers & Interactive Lab Tracker

The hallmark of professional, safe biohacking is letting objective lab biomarkers guide every protocol. Calculate your HOMA-IR insulin resistance score below and inspect full reference ranges across key organ safety markers.

Interactive Lab Biomarker & HOMA-IR Calculator

Input fasting lab values to calculate HOMA-IR and evaluate metabolic health and peptide safety

Enter Fasting Lab Panel Values
Normal fasting range: 3.9 - 5.6 mmol/L (70-100 mg/dL)
Ideal biohacker target: < 8.0 uIU/mL
Normal < 40 U/L
Normal 50-105
Optimal 180-240
Normal 28-100
HOMA-IR Insulin Resistance Score
3.48Severe Insulin Resistance

HOMA-IR > 2.5 indicates severe insulin resistance and metabolic dysfunction.

Clinical Action Blueprint for Biohackers:
  • Candidate for GLP-1/GIP dual-agonists (Tirzepatide 2.5mg-5.0mg) to reverse hyperinsulinemia and reset hypothalamic satiety.

Verified reference targets and critical safety action thresholds for biohackers

Metabolic & InsulinBaseline pre-cycle, week 8, and week 16

Fasting Insulin & HOMA-IR Index

Fasting Insulin & HOMA-IR Index
Ideal Target Range: Fasting insulin < 6.0 μIU/mL; HOMA-IR < 1.4

Flags metabolic syndrome 5–10 years earlier than standard fasting glucose. Dual GLP-1/GIP agonists like Tirzepatide typically normalize severe insulin resistance (4.0+) back down below 1.5.

Associated Peptides: Tirzepatide · Semaglutide · Retatrutide · MK-677
🚨 Critical Action Threshold: If using MK-677 and fasting insulin exceeds 15 μIU/mL or fasting glucose exceeds 6.1 mmol/L, reduce dose or add berberine/metformin intervention immediately.
Organ SafetyBaseline pre-cycle, and immediately if persistent severe abdominal pain occurs

Serum Amylase & Lipase

Serum Amylase & Lipase
Ideal Target Range: Lipase 10–60 U/L; Amylase 28–100 U/L

GLP-1 agonists delay gastric motility and stimulate pancreatic exocrine secretion. Monitoring lipase and amylase screens for occult acute or chronic pancreatitis risk.

Associated Peptides: Tirzepatide · Semaglutide · Retatrutide
🚨 Critical Action Threshold: Severe radiating epigastric pain accompanied by lipase or amylase >3x upper reference limit requires immediate drug cessation and emergency medical care.
Hormone SecretionBaseline, week 4, and week 8 of secretagogue cycle

IGF-1 (Insulin-like Growth Factor 1)

IGF-1 (Insulin-like Growth Factor 1)
Ideal Target Range: Age-dependent; typical healthy adult midpoint (ages 30–50): 150–240 ng/mL

commonly used biomarker to assess real-world secretagogue potency for CJC-1295, Ipamorelin, and MK-677.

Associated Peptides: CJC-1295 + Ipamorelin · MK-677 · Epithalon
🚨 Critical Action Threshold: Target youthful optimal ceiling (~200–260 ng/mL). Sustained values >350 ng/mL increase cellular proliferation risks; pause cycle immediately.
MicronutrientsRe-test whenever GHK-Cu is used continuously for more than 8 weeks

Serum Copper / Zinc Ratio

Serum Copper / Zinc Ratio
Ideal Target Range: Serum zinc/copper molar ratio approximately 1.0–1.2

Protracted high-dose subcutaneous GHK-Cu leads to exogenous copper accumulation and competitive inhibition of intestinal zinc uptake.

Associated Peptides: GHK-Cu
🚨 Critical Action Threshold: Elevated copper alongside low free zinc triggers fatigue, immune suppression, and hair loss; daily co-supplementation with 15–30mg Zinc Gluconate is mandatory during GHK-Cu cycles.
Organ SafetyPrior to injury recovery cycles and at week 4

High-Sensitivity CRP (hs-CRP)

High-Sensitivity CRP (hs-CRP)
Ideal Target Range: < 1.0 mg/L (minimal cardiovascular and systemic chronic inflammatory risk)

Core biomarker of systemic sterile low-grade inflammation and connective tissue damage. BPC-157 and KPV significantly lower elevated hs-CRP.

Associated Peptides: BPC-157 · TB-500 · KPV · Tirzepatide
🚨 Critical Action Threshold: If hs-CRP spikes >10 mg/L within 24 hours of an injection, suspect high endotoxin pyrogen contamination from unpurified research vials.
Organ SafetyBaseline pre-cycle, and at week 12

Liver Function Panel (ALT/AST/GGT)

Liver Function Panel (ALT/AST/GGT)
Ideal Target Range: ALT < 40 U/L, AST < 35 U/L, GGT < 45 U/L

Triple-agonist Retatrutide and dual-agonist Tirzepatide substantially mobilize hepatic ectopic lipid deposition, reversing NAFLD and normalizing elevated transaminases.

Associated Peptides: Retatrutide · Tirzepatide · Semaglutide
🚨 Critical Action Threshold: Mild transient transaminase elevation can occur during rapid fat mobilization; persistent elevation >3x upper limit warrants ultrasound screening for biliary sludge or gallstones.

💡 4 Golden Rules for Clinical Blood Testing

① Strict Fasting Window:For fasting glucose, insulin, and lipid panels, fast for at least 10 hours overnight before morning draw.
② Avoid Acute Heavy Lifting:Heavy resistance training within 48h falsely elevates AST, ALT, and creatine kinase.
③ Consistent Sampling Times:Growth hormone, IGF-1, and cortisol follow circadian rhythms. Draw between 8:00 AM - 9:30 AM.
④ Zinc-Copper Fasting:Pause oral zinc and copper supplements 24h prior to testing to accurately measure serum levels.
