Dosing Protocols for Peptides
Evidence-based dosing guidelines for various peptide classes, including titration strategies, timing optimization, and individualization principles.
Introduction
Proper dosing is critical for achieving desired results while minimizing side effects. This guide provides comprehensive dosing protocols based on available evidence and practitioner experience.
General Dosing Principles
Start Low, Go Slow
- Begin at lowest effective dose
- Titrate up based on response
- Allow 2-4 weeks between increases
- Monitor for side effects at each level
Individual Variation
Factors affecting optimal dose:
- Body weight and composition
- Age and metabolic rate
- Receptor sensitivity
- Previous peptide use
- Concurrent medications
- Health status

Notes: Rapid desensitization; limit to 4-8 weeks
Growth Hormone Releasing Hormones (GHRHs)
CJC-1295 (with DAC)
| Protocol | Dose | Frequency | Notes |
|---|---|---|---|
| Standard | 1-2 mg | 1-2x weekly | Long half-life |
| Conservative | 1 mg | Weekly | Steady elevation |
Timing: Consistent weekly schedule Notes: Sustained GH elevation; pair with GHRP for pulse
CJC-1295 (no DAC) / Mod GRF 1-29
| Protocol | Dose | Frequency | Notes |
|---|---|---|---|
| Standard | 100 mcg | 2-3x daily | Short half-life |
| With GHRP | 100 mcg each | 2-3x daily | Synergistic stack |
Timing: Same timing as paired GHRP Notes: Always use with GHRP for best results
Sermorelin
| Phase | Dose | Frequency | Duration |
|---|---|---|---|
| Initiation | 200 mcg | Once daily (evening) | Week 1-2 |
| Standard | 200-500 mcg | Once daily | Ongoing |
Timing: Before bed (mimics natural GH pulse) Notes: Gentler profile; good for beginners
Recovery Peptides
BPC-157
| Protocol | Dose | Frequency | Duration |
|---|---|---|---|
| Systemic | 250-500 mcg | 1-2x daily | 4-8 weeks |
| Local (injury) | 200-300 mcg | 1-2x daily near site | 4-6 weeks |
| Oral (stable form) | 500 mcg | 1-2x daily | 4-8 weeks |
Administration: Subcutaneous or intramuscular (near injury) Notes: Can use orally for gut issues; injectable for systemic
TB-500
| Phase | Dose | Frequency | Duration |
|---|---|---|---|
| Loading | 2-2.5 mg | 2x weekly | 4-6 weeks |
| Maintenance | 2 mg | Weekly | Ongoing as needed |
| Acute injury | 2.5 mg | 2x weekly | 2-4 weeks |
Administration: Subcutaneous or intramuscular Notes: Systemic effects; loading phase important
Metabolic Peptides
Tesamorelin
| Protocol | Dose | Frequency | Notes |
|---|---|---|---|
| Standard | 2 mg | Daily | FDA-approved dose |
| Research | 1-2 mg | Daily | Titrate based on response |
Timing: Morning or evening, consistent timing Notes: FDA-approved for lipodystrophy
MOTS-c
| Protocol | Dose | Frequency | Notes |
|---|---|---|---|
| Conservative | 5 mg | 2x weekly | Starting protocol |
| Standard | 10 mg | 2-3x weekly | Typical use |
| Performance | 10-15 mg | 3x weekly | Higher dose |
Timing: Training days; some prefer fasted Notes: Emerging peptide; dosing still being optimized
HGH Fragment 176-191
| Protocol | Dose | Frequency | Notes |
|---|---|---|---|
| Fat loss | 250-500 mcg | 2x daily | Morning + pre-bed |
| Aggressive | 500 mcg | 2x daily | Maximum typical dose |

Stacking Protocols
GH Secretagogue Stack
| Component | Dose | Timing |
|---|---|---|
| CJC-1295 (no DAC) | 100 mcg | Same injection |
| Ipamorelin | 200 mcg | Same injection |
| Frequency | - | 2-3x daily |
Recovery Stack
| Component | Dose | Timing |

Injection Technique Optimization
Subcutaneous Administration
- Rotate injection sites (abdomen, thigh, deltoid)
- Use 29-31 gauge insulin needles
- Inject at 45-90 degree angle
- Clean site with alcohol
- Allow alcohol to dry before injection
Timing Considerations
| Peptide Type | Optimal Timing | Avoid |

| GH secretagogues | Empty stomach | Within 2 hours of meal |
| BPC-157 | Any time | No restrictions |
| TB-500 | Any time | No restrictions |
| Fragment | Fasted | High-carb meals |
Reconstitution Guidelines
Bacteriostatic Water Volumes
| Peptide Amount | BAC Water | Per 0.1 mL (10 IU) |
|---|---|---|
| 2 mg | 2 mL | 100 mcg |
| 5 mg | 2 mL | 250 mcg |
| 5 mg | 2.5 mL | 200 mcg |
| 10 mg | 2 mL | 500 mcg |
Storage After Reconstitution
- Refrigerate at 36-46°F (2-8°C)
- Use within 3-4 weeks
- Avoid freezing reconstituted peptides
- Protect from light
Conclusion
Proper dosing requires attention to individual response, careful titration, and consistent administration. Start conservatively, monitor closely, and adjust based on results and side effects.
