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

Growth Hormone Releasing Peptides (GHRPs)

GHRP-2

Phase Dose Frequency Duration
Initiation 100 mcg 1x daily Week 1-2
Standard 100-200 mcg 2-3x daily Ongoing
Aggressive 200-300 mcg 3x daily Limited periods

Timing: Upon waking, post-workout, before bed Notes: Stimulates appetite; may increase cortisol at high doses

GHRP-6

Phase Dose Frequency Notes
Standard 100 mcg 2-3x daily Significant hunger stimulation
Maximum 200 mcg 3x daily Strong GH release

Timing: 30 minutes before meals (enhances appetite) Notes: Strongest hunger effect of GHRPs

Ipamorelin

Phase Dose Frequency Duration
Conservative 100 mcg 2x daily Long-term
Standard 200-300 mcg 2-3x daily Typical use
Saturation 300 mcg 3x daily Maximum effect

Timing: Upon waking, post-workout, before bed Notes: Cleanest GHRP; minimal appetite/cortisol effects

Hexarelin

Phase Dose Frequency Notes
Initiation 100 mcg 1x daily Week 1-2
Standard 100-200 mcg 2x daily Stronger desensitization

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

Timing: Fasted states (morning, before bed) Notes: Fat-specific; no GH effects on glucose

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
BPC-157 250 mcg Morning
TB-500 2 mg 2x weekly

Fat Loss Stack

Component Dose Timing
CJC-1295 + Ipamorelin 100/200 mcg Pre-bed
Fragment 176-191 500 mcg Fasted AM

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.
