— About this compound

What CJC-1295 with DAC is

CJC-1295 with DAC is a synthetic analog of growth hormone-releasing hormone, modified with a drug affinity complex that substantially extends its circulating half-life relative to the unmodified peptide. It is supplied lyophilised under inert atmosphere.

How CJC-1295 with DAC
has been studied.

Signalling pathways examined in preclinical models. Descriptive of published research directions, not claims of effect.

Receptor

GHRH receptor binding

Characterised in receptor-binding studies against the growth hormone-releasing hormone receptor on pituitary-derived cell lines.

  • Assessed in GHRH receptor binding assays
  • Compared against native GHRH(1-29)
  • Examined in pituitary cell preparations
Pharmacokinetics

Half-life extension

The drug affinity complex is designed to form a covalent bond with serum albumin, which is the mechanism by which circulating duration is extended in preclinical models.

  • Albumin-binding conjugate chemistry
  • Studied in plasma stability preparations
  • Compared against non-DAC analog

About CJC-1295 with DAC

Still unsure? Ask the lab — median response under four hours.

DAC stands for drug affinity complex — a chemical modification that allows the peptide to bind serum albumin, substantially extending its circulating half-life in preclinical models compared with the unmodified analog.

Store the sealed vial at −20°C for long-term stability and 2–8°C for short-term handling. Protect from light and avoid repeated freeze-thaw cycles. Compound-specific stability data is printed on the certificate of analysis supplied with the lot.
