Growth-Hormone Axis
CJC-1295 (No DAC)
Also known as Mod GRF 1-29
A short-acting GHRH analogue that produces a clean, brief growth-hormone pulse closely mirroring the body's natural rhythm.
What it is
CJC-1295 without DAC — often called Mod GRF 1-29 — is a stabilised fragment of GHRH. Unlike the DAC version, it acts briefly, producing a sharp, short-lived growth-hormone pulse.
How it's thought to work
It stimulates the same pituitary GHRH receptors but clears quickly. This short action is considered more physiological: it mimics the natural, pulsatile way growth hormone is released, then lets levels return to baseline.
Potential health benefits
Research interest includes:
- Pulsatile growth-hormone support that respects natural feedback.
- Recovery and lean-mass goals.
- Pairing with a secretagogue like Ipamorelin for a stronger, well-timed pulse.
What the research says
The short half-life makes it popular in research designs that aim to preserve the body's normal rhythm. As with most GHRH peptides, controlled long-term human outcome data is limited.
Considerations
A research compound, not an approved therapy. Seek qualified medical advice before use.
