GH Optimization Stack
The classic growth hormone secretagogue combination for improving body composition, recovery, and sleep quality through amplified, physiological GH release.
Comparison Summary
Research Overview
CJC-1295 (without DAC) and Ipamorelin work on two different receptor pathways to produce a synergistic amplification of growth hormone release. CJC-1295 acts on GHRH receptors while Ipamorelin acts on ghrelin receptors — together they produce a GH pulse 3–5x greater than either peptide alone, while maintaining the natural pulsatile pattern that avoids receptor desensitization.
Peptide Breakdown
CJC-1295 (no DAC)
Administer on an empty stomach, ideally before sleep
Ipamorelin
Inject simultaneously with CJC-1295 for synergistic effect
Research Context
Improved sleep depth and quality within 1–2 weeks. Progressive improvements in body composition (fat loss, lean mass gain) over 8–12 weeks. Enhanced recovery, skin quality, and energy levels. Mild water retention in the first 2 weeks is common.
Research Notes
CJC-1295 has been studied in a Phase II clinical trial showing sustained GH and IGF-1 elevation. Ipamorelin is considered the most selective GHRP with minimal cortisol or prolactin elevation.

Cautions & Contraindications
Use with caution in insulin-resistant individuals — GH elevation can affect insulin sensitivity. Not for use with active malignancy or during pregnancy.
