CJC-1295 (no DAC) / Mod GRF 1-29

Research Use Only
peptideInjection

Shorter-acting GH booster that releases growth hormone in natural pulses. Clears faster without DAC, so it's usually paired with another GH peptide for stronger effect.

Key Facts

  • Classification
    Modified GRF (1-29), a truncated GHRH analog with substitutions at positions 2, 8, 15, and 27 for enhanced receptor affinity and DPP-IV resistance.
  • Primary Benefits
    Muscle Growth (7/10) · Fat Loss (6/10) · Longevity (4/10)
  • Administration
    Injection
  • Typical Dose
    100 mcg subq 2-3 times daily, ideally paired with a GH-releasing peptide like Ipamorelin. Cycle for 8-12 weeks.
  • Evidence Strength
    Moderate — 15 peer-reviewed studies referenced · Community sentiment 9/10
  • Stacks Well With
    Ipamorelin, GHRP-6, GHRP-2
  • Legal Status
    Research Use Only · not prescribable in US · WADA prohibited

1

Week 1–2

Improved sleep quality, especially deeper sleep. Subtle increase in morning energy. GH pulses become more pronounced.

2

Week 3–6

Enhanced recovery between workouts. Mild fat loss beginning. Improved skin elasticity and hydration. Better overall sense of vitality.

3

Week 8+

Meaningful body composition changes. Connective tissue strengthening. Sustained energy improvements. Best results when combined with a GHRP like Ipamorelin.

Common Side Effects

Mild water retentionFlushing at injection siteHunger increaseTingling in extremities (rare)
Tolerance: Minimal — pulsatile dosing preserves receptor sensitivity
Cycling: 12-16 weeks on, 4-6 weeks off. Can be run longer than the DAC version.

Scientific Overview

Modified GRF (1-29), a truncated GHRH analog with substitutions at positions 2, 8, 15, and 27 for enhanced receptor affinity and DPP-IV resistance. ~30-minute half-life produces acute GH pulses mimicking physiological secretion. Often combined with Ipamorelin for synergistic pituitary stimulation.

Dosing

100 mcg subq 2-3 times daily, ideally paired with a GH-releasing peptide like Ipamorelin. Cycle for 8-12 weeks.
