CJC-1295 with DAC is a synthetic peptide analog of Growth Hormone–Releasing Hormone (GHRH) that has been engineered to increase the duration and stability of growth-hormone stimulation by extending the peptide’s half-life in the body. It is one of the most well-known long-acting GHRH analogs used in research and investigational settings.

What CJC-1295 with DAC Is

• Peptide type: Synthetic GHRH analog

• Length: 30 amino acids (modified)

• DAC: Drug Affinity Complex (a chemical modification that binds to albumin)

• Primary function: Long-acting stimulation of growth hormone (GH) release

• Status: Research / investigational compound

• Regulatory status: Not approved for general therapeutic use

What the “DAC” Does

The Drug Affinity Complex (DAC) is the key feature that differentiates this version from standard CJC-1295 (without DAC):

• Enables reversible binding to serum albumin

• Dramatically extends half-life (days instead of minutes)

• Produces sustained GH release rather than short pulses

• Reduces frequency of administration in research models
