CJC-1295 DAC Research Peptide

CJC-1295 DAC is a high-purity synthetic GHRH analogue engineered with Drug Affinity Complex technology for extended biological activity in controlled research settings. Available exclusively from Direct Anti Peptide at ≥98% purity, this peptide represents a reliable, analytically verified research tool for qualified laboratory professionals. For research use only. Not for human or veterinary use. Not for clinical, diagnostic, or consumptive applications.

Product Overview

CJC-1295 DAC is a modified synthetic peptide derived from the first 29 amino acids of endogenous growth hormone-releasing hormone. The incorporation of the Drug Affinity Complex (DAC) moiety — specifically a lysine-linked maleimidoproprionic acid (MPA) group — enables covalent binding to circulating serum albumin. This binding mechanism dramatically prolongs the peptide’s half-life compared to native GHRH analogues, making it a compelling subject for research into sustained growth hormone axis modulation. Direct Anti Peptide supplies this compound to qualified researchers seeking consistent, high-grade material for in vitro and preclinical investigation.

Peptide Structure & Amino Acid Sequence

CJC-1295 DAC is a 30-amino acid peptide with the sequence: 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, with the DAC moiety conjugated at the epsilon-amine of the C-terminal lysine residue. This structural modification is the defining feature that confers albumin-binding capacity and extended plasma persistence, distinguishing it from CJC-1295 without DAC. Researchers studying GHRH receptor interactions, pulsatile hormone release dynamics, and long-acting peptide pharmacokinetics will find this structural profile of particular scientific relevance.

Purity & Analytical Verification (HPLC & MS)

Every batch of CJC-1295 DAC supplied by Direct Anti Peptide is independently verified to a minimum purity of ≥98% using reverse-phase high-performance liquid chromatography (RP-HPLC). Mass spectrometry (MS) confirmation is performed to validate the molecular identity and confirm the correct DAC conjugation. Certificates of Analysis (CoA) documenting these analytical results are available upon request, providing researchers with full traceability and confidence in the compound’s identity and quality. Our commitment to rigorous analytical verification ensures that every vial meets the high standards demanded by serious research environments.

Quality Control & Lyophilization Integrity

CJC-1295 DAC is manufactured under controlled conditions and subjected to a multi-stage quality control process prior to dispatch. Lyophilization is performed using validated freeze-drying protocols that preserve peptide structural integrity, minimize oxidation risk, and ensure long-term stability. Each vial is sealed under inert atmosphere conditions to prevent moisture ingress and degradation. Batch-level quality records are maintained to support reproducibility across research studies, and all material is handled in compliance with standard laboratory manufacturing practices.

Safety, Handling & Laboratory Precautions

CJC-1295 DAC is a research-grade chemical intended exclusively for use by trained laboratory professionals in appropriately equipped facilities. Standard laboratory safety protocols must be observed at all times, including the use of appropriate personal protective equipment (PPE) such as gloves, lab coat, and eye protection. Researchers should consult applicable institutional biosafety guidelines and Safety Data Sheets (SDS) before handling. This compound is not approved for any human or animal administration and must be stored securely, away from unauthorized personnel.

Reconstitution, Packaging & Storage

CJC-1295 DAC is supplied as a lyophilized powder in sealed research-grade vials. Reconstitution should be performed strictly in accordance with established laboratory protocols using appropriate research-grade solvents. This product is not intended for injection or any form of biological administration. Upon receipt, vials should be stored at −20°C in a dry, dark environment to maintain optimal stability. Once reconstituted for in vitro research purposes, the solution should be aliquoted and stored at −80°C where applicable. Avoid repeated freeze-thaw cycles to preserve compound integrity.

Intended Research Use & Market Positioning

CJC-1295 DAC is positioned as a premium research peptide for investigators studying the growth hormone-releasing hormone axis, pulsatile GH secretion, IGF-1 pathway modulation, and long-acting peptide conjugation strategies. It is also of interest in preclinical research contexts exploring metabolic regulation, body composition dynamics, and cellular repair mechanisms at the molecular level. Direct Anti Peptide supplies this compound to academic institutions, pharmaceutical research organizations, and independent laboratories requiring reliable, high-purity peptide material.
