CJC-1295 with DAC: What It Is (Research Overview)

CJC-1295 with DAC is a synthetic growth hormone-releasing hormone (GHRH) analog designed to stimulate the pituitary gland to increase natural growth hormone (GH) and IGF-1 levels. (Peptidepedia)

The key feature is the DAC (Drug Affinity Complex), which allows the peptide to bind to albumin in the blood, dramatically extending its activity. (Peptide Reference)

How It Works

• Mimics natural GHRH signals
• Binds to pituitary GHRH receptors
• Stimulates pulses of growth hormone release
• Increases downstream IGF-1 levels

Because of the DAC modification, it stays active for ~6–8 days, unlike the short-acting version that lasts ~30 minutes. (Peptides Institute)

Why It’s Studied

Researchers and clinics study CJC-1295 DAC for its effects on:

• Growth hormone / IGF-1 axis
• Body composition (fat vs lean mass)
• Recovery and tissue repair signaling
• Sleep and metabolic regulation

CJC-1295 DAC vs No DAC

• With DAC: long-lasting, steady GH elevation (days)
• Without DAC (Mod GRF 1-29): short pulses, closer to natural hormone rhythm

---

Important Safety Context

• It is not an approved medication in most countries
• Human clinical data is limited compared with regulated therapies
• Reported concerns include hormone imbalance risks and variability in product purity in non-regulated markets

Bottom line

CJC-1295 DAC is a long-acting experimental GHRH analog studied for growth hormone stimulation, but it remains a research-only compound with limited regulatory approval and incomplete safety data.
