What is CJC-1295 no DAC?

CJC-1295 without DAC, commonly known as Mod-GRF 1-29, is a modified GHRH analog that lacks the albumin-binding drug-affinity complex, resulting in a shorter half-life. It is studied in research related to the growth-hormone axis and GHRH receptor signalling, with a focus on more transient receptor engagement.

GHRH-analog research generally examines effects on growth-hormone pulsatility, downstream IGF-1 signalling, and receptor activity. The non-DAC form is investigated for its shorter action profile, often compared against DAC-modified analogs in preclinical research.

Areas of research

📈

GH-axis signalling

Studied for GHRH receptor effects on growth-hormone-axis activity in research models.

🌊

Pulsatile profile

Investigated for shorter, more transient receptor engagement compared to DAC-modified analogs.

🔄

IGF-1 pathway

Examined for downstream IGF-1 signalling associated with GHRH receptor stimulation in research.

🔬

Receptor activity

Characterized through assays defining its GHRH receptor agonism and signalling profile.

In the lab: reconstitution

1

Bring the vial (10 mg) and bacteriostatic water to room temperature.

2

Add bacteriostatic water slowly along the glass wall — the volume you add sets the concentration.

3

Swirl gently (do not shake) until fully clear, then refrigerate at 2–8 °C.

Tip: The Peptide Calculator converts any vial size and water volume into units per syringe mark automatically.

FAQ

What is CJC-1295 no DAC?

Also called Mod-GRF 1-29, it is a GHRH analog lacking the drug-affinity complex, giving it a shorter half-life. It is studied for growth-hormone-axis signalling in research.

How does it differ from the DAC version?

Without the albumin-binding DAC, it has a shorter circulating time, so it is studied for a more transient action profile compared to CJC-1295 with DAC.

What is it researched for?

It is studied in the context of GHRH receptor activity, growth-hormone-axis signalling, and downstream IGF-1 pathways within preclinical research models.
