Structure, physicochemical data, analytical verification and safety documentation for CJC-1295 (with DAC). Supplied for in-vitro laboratory research only.
Two-dimensional structures generated with RDKit and drawn in the site palette. Tap a drawing to enlarge it. Below each drawing, the residue chain in one-letter code with the three-letter name and position; colours mark the side-chain class, a dashed outline marks a D-residue or a non-proteinogenic residue (lower-case letters are D-residues).
2D depiction, C165H269N47O46, generated from the PubChem connection table, CID 91971820.
H-Tyr-D-Ala-Asp-Ala-Ile-Phe-Thr-Gln-Ser-Tyr-Arg-Lys-Val-Leu-Ala-Gln-Leu-Ser-Ala-Arg-Lys-Leu-Leu-Gln-Asp-Ile-Leu-Ser-Arg-Lys(MPA)-NH2 (terminal groups: N-terminal free amine, C-terminal amide)
Formula, masses and identifiers from PubChem where a record exists, checked against an independent RDKit calculation and, for peptides, against the residue sequence. Theoretical pI, net charge at pH 7.4, GRAVY and the 280 nm extinction coefficient are calculated with Biopython ProtParam on the residue chain (Bjellqvist pK set; Kyte-Doolittle; Gill and von Hippel) and are marked "calculated"; they are not given where the chain contains non-proteinogenic residues.

CJC-1295 is a synthetic Growth Hormone-Releasing Hormone (GHRH) analog developed for laboratory research. Researchers continue studying it in studies about receptor pharmacology, peptide engineering, and pharmacokinetics.
DAC stands for Drug Affinity Complex. This is a molecular modification designed to prolong its circulation by enabling covalent conjugation with serum albumin.
Published research investigates CJC with DAC in areas including:
• GHRH receptor pharmacology
• Endocrine signalling
• Pituitary biology
• Peptide pharmacokinetics
• Albumin conjugation
• Long-acting peptide engineering
HPLC separates peptide material from impurities. A reported purity of 99%+ indicates that at least 99% of the analyzed sample consists of the target peptide.
Store unopened lyophilized vials at -20°C for long-term preservation. After reconstitution, refrigerate below 4°C and avoid repeated freeze-thaw cycles.
No. We supply CJC-1295 exclusively for laboratory, analytical, and scientific research. It is not approved for human consumption, therapeutic use, veterinary applications, or diagnostic procedures.
Lyophilization removes water from the peptide under low-temperature, low-pressure conditions, producing a stable white powder.
Because moisture is removed during manufacturing, lyophilized peptides generally demonstrate greater stability during storage than peptides supplied in solution.
