Peptide Dosage Chart: Quick Reference for Common Peptides
A comprehensive quick-reference dosage chart covering common peptides with typical doses, frequencies, administration routes, and half-lives.
How to Use This Chart
This reference chart provides commonly cited dose ranges, administration frequencies, routes, and half-lives for popular peptides. Doses are organized by conservative (starting), standard, and upper ranges based on available research literature and clinical protocols.
Important: These are reference ranges, not prescriptions. Individual dosing should be determined by a healthcare provider based on your specific situation, health status, and goals. Use the Dosage Calculator to calculate weight-adjusted doses for your body weight.
Healing and Recovery Peptides
| Peptide | Conservative Dose | Standard Dose | Upper Dose | Frequency | Route | Half-Life |
|---|---|---|---|---|---|---|
| BPC-157 | 200 mcg | 250–500 mcg | 500–750 mcg | 1–2x daily | SubQ | ~4 hours |
| TB-500 | 750 mcg | 2–2.5 mg | 4–5 mg | 2x/week | SubQ | ~6 hours |
| GHK-Cu | 200 mcg | 500 mcg | 1 mg | 1x daily | SubQ | ~30 min |
Notes on Healing Peptides
- BPC-157 is commonly injected near the injury site for localized effect, though systemic effects occur regardless
- TB-500 is administered systemically — injection site does not need to be near the injury
- GHK-Cu is also available topically for skin applications; SubQ dosing is for systemic use
- Loading phases (higher initial doses for 2–4 weeks) are common with TB-500
Growth Hormone Secretagogues
| Peptide | Conservative Dose | Standard Dose | Upper Dose | Frequency | Route | Half-Life |
|---|---|---|---|---|---|---|
| Ipamorelin | 100 mcg | 200 mcg | 300 mcg | 2–3x daily | SubQ | ~2 hours |
| CJC-1295 (no DAC) | 100 mcg | 100–200 mcg | 200 mcg | 2–3x daily | SubQ | ~30 min |
| CJC-1295 (with DAC) | 1 mg | 2 mg | 2 mg | 1x/week | SubQ | ~7 days |
| Sermorelin | 100 mcg | 200–300 mcg | 500 mcg | 1x daily (bedtime) | SubQ | ~10–20 min |
| GHRP-2 | 100 mcg | 200 mcg | 300 mcg | 2–3x daily | SubQ | ~1 hour |
| GHRP-6 | 100 mcg | 200 mcg | 300 mcg | 2–3x daily | SubQ | ~2 hours |
Notes on GH Secretagogues
- Administer on an empty stomach — food blunts GH release
- Ipamorelin + CJC-1295 (no DAC) is the most common stack
- Bedtime dosing is generally the most important window
- Use the Half-Life Visualizer to model blood concentration curves
GLP-1 and Metabolic Peptides
| Peptide | Starting Dose | Maintenance | Maximum | Frequency | Route | Half-Life |
|---|---|---|---|---|---|---|
| Semaglutide | 0.25 mg | 1.0 mg | 2.4 mg | 1x/week | SubQ | ~7 days |
| Tirzepatide | 2.5 mg | 5–10 mg | 15 mg | 1x/week | SubQ | ~5 days |
| Retatrutide | 1 mg | 4–8 mg | 12 mg | 1x/week | SubQ | ~6 days |
| AOD-9604 | 100 mcg | 250–300 mcg | 500 mcg | 1x daily | SubQ | ~1 hour |
Notes on GLP-1 Peptides
- All GLP-1 agonists require slow titration — increase every 4 weeks minimum
- Semaglutide and tirzepatide are prescription medications
- GI side effects (nausea, constipation) are dose-dependent and typically improve over time
Anti-Aging and Other Peptides
| Peptide | Conservative Dose | Standard Dose | Upper Dose | Frequency | Route | Half-Life |
|---|---|---|---|---|---|---|
| Epithalon | 5 mg | 10 mg | 10 mg | 1x daily (10-day cycles) | SubQ/IM | ~2 hours |
| DSIP | 50 mcg | 100 mcg | 200 mcg | Before bed | SubQ | ~15 min |
| Selank | 250 mcg | 500 mcg | 750 mcg | 1–2x daily | Intranasal/SubQ | ~3 min |
| PT-141 | 0.5 mg | 1.75 mg | 2 mg | As needed (max 1x/day) | SubQ | ~2 hours |
Weight-Based Dose Ranges
For peptides typically dosed by body weight:
| Peptide | Low | Standard | High |
|---|---|---|---|
| BPC-157 | 3 mcg/kg | 5 mcg/kg | 10 mcg/kg |
| Ipamorelin | 1 mcg/kg | 2 mcg/kg | 3 mcg/kg |
| CJC-1295 (no DAC) | 1 mcg/kg | 1.5 mcg/kg | 2 mcg/kg |
Use the Dosage Calculator to calculate your exact dose based on these mcg/kg ranges.
How to Read the Chart
- Conservative dose: Starting dose for new users or sensitive individuals
- Standard dose: Most commonly cited effective dose in research
- Upper dose: Higher end of studied ranges — not necessarily better
- Frequency: How often each dose is administered
- Route: SubQ = subcutaneous, IM = intramuscular
- Half-life: Time for blood concentration to drop by 50%
