GH Optimization Protocol
Overview
The GH Optimization Protocol restores youthful growth hormone pulsatility using GHRH + GHRP combinations that amplify the natural GH axis without suppressing endogenous production. Unlike exogenous HGH, secretagogue combinations preserve the pulsatile, physiological GH pattern and the negative feedback mechanisms that prevent excess. Primary benefits include improved body composition (lean mass gain, fat reduction), better sleep architecture, enhanced recovery, improved skin quality, and IGF-1 normalization. CJC-1295 No DAC + Ipamorelin is the most commonly used and well-tolerated combination.
Components
| Peptide | Dose | Frequency | Duration |
|---|---|---|---|
| CJC-1295 (No DAC) | 100 mcg | Nightly, pre-sleep, fasted | 8-12 weeks |
| Ipamorelin | 100 mcg | Nightly, pre-sleep, fasted | 8-12 weeks |
Alternative / advanced option:
| Peptide | Dose | Frequency | Duration |
|---|---|---|---|
| Tesamorelin | 1-2 mg | Nightly, pre-sleep, fasted | 12 weeks |
| Ipamorelin | 100 mcg | Nightly, pre-sleep, fasted | 12 weeks |
Administration
- Route: SubQ injection; abdomen, thigh, or deltoid
- Timing: Immediately before sleep; the pre-sleep window captures the natural GH pulse during slow-wave sleep and produces the largest GH response
- Fasting requirement: Must be taken fasted (2-3 hours after last meal); insulin and glucose blunt GH release; this is critical for protocol efficacy
- Schedule: 5 days on / 2 days off (typically Mon-Fri dosing, weekend off) to maintain pituitary receptor sensitivity
- Reconstitute with bacteriostatic water; stable refrigerated for 30 days after reconstitution
Cycling
- On: 8-12 weeks
- Off: 4-8 weeks minimum (allows pituitary to reset and prevents desensitization)
- Some clinicians use longer cycles (16-24 weeks) at lower doses; extend off period proportionally
- IGF-1 levels can be used to guide cycling decisions
Expected Timeline
- Week 1-2: Improved sleep depth and vivid dreams; morning alertness
- Week 3-4: Subtle body composition shifts; improved recovery from exercise
- Week 5-8: Visible fat reduction and lean mass improvement; improved skin firmness
- Week 9-12: Peak body composition changes; IGF-1 levels near peak; joint and connective tissue improvements
Monitoring
- IGF-1 blood test at baseline, week 6, and end of cycle; target upper-normal range
- Fasting glucose and insulin — GH secretagogues can induce transient insulin resistance
- Track body composition (DEXA or circumference measurements)
- Monitor for fluid retention (edema), joint pain, or tingling (carpal tunnel-like) — dose-related and resolve with lower dose
Contraindications
- Active cancer or strong family history of hormone-sensitive cancers
- Uncontrolled diabetes (GH can worsen insulin resistance)
- Pituitary tumors or history of pituitary disease
- Pregnancy or breastfeeding
- Children and adolescents (still growing)
