To successfully micro-procure or bulk acheter CJC-1295 DAC for experimental protocols, principal investigators require analytical-grade material backed by verifiable quality control documentation. CJC-1295 with Drug Affinity Complex (DAC) is a synthetic 30-amino acid tetrasubstituted peptide derivative designed to function as a long-acting growth hormone-releasing hormone (GHRH) agonist in cell culture and animal models.
When purchasing compounds for cellular signaling or metabolic assays, laboratory buyers must distinguish between unverified domestic re-sellers and authentic research suppliers. PX1 Research synthesizes CJC-1295 DAC in GMP-compliant facilities within the United States, providing lot-specific certificates of analysis (COAs) generated by ISO 17025 accredited testing laboratories. This ensures that every vial meets strict parameters for purity, molecular weight, and endotoxin thresholds before deployment in scientific study.
CJC-1295 DAC is a modified bioconjugate derived from the first 29 amino acids of human GHRH (growth hormone-releasing hormone). The primary structural innovation in this compound is the addition of a lysine residue at the C-terminus, attached to a maleimidopropionic acid reactive group—collectively designated as the Drug Affinity Complex (DAC). Preclinical studies indicate that upon administration in rodent or non-human primate models, this maleimide group rapidly forms a covalent bond specifically with the free thiol group at Cys34 of circulating serum albumin.
Native GHRH and non-conjugated analogs exhibit an extremely short plasma half-life—typically between 5 to 30 minutes—due to rapid enzymatic cleavage by dipeptidyl peptidase IV (DPP-IV) and renal filtration. In contrast, the covalent binding to serum albumin creates a macromolecular complex that protects the peptide backbone from proteolytic degradation. In vitro data indicate that this conjugation extends the biological half-life of the active GHRH sequence to several days, enabling continuous activation of the GHRH receptor (GHRH-R) on pituitary somatotropes without requiring continuous infusion equipment.
In animal model research, CJC-1295 DAC has been extensively investigated for its capacity to stimulate growth hormone (GH) synthesis and secretion. Unlike pulsatile secretagogues, the persistent GHRH-R agonism induced by CJC-1295 DAC generates a sustained, baseline elevation of systemic growth hormone. Preclinical studies suggest that this prolonged somatotropic stimulation leads to downstream upregulation of hepatic insulin-like growth factor 1 (IGF-1) production.
Researchers utilizing somatotropic models study these elevated IGF-1 kinetics in contexts such as cellular proliferation, nitrogen balance retention, protein synthesis assays, and tissue repair dynamics. Because IGF-1 plays a vital role in skeletal muscle hypertrophy, collagen matrix cross-linking, and chondrocyte metabolism, CJC-1295 DAC remains a foundational tool in our catalog of research peptides dedicated to endocrinological and musculoskeletal research.
When designing preclinical trials, researchers often evaluate CJC-1295 DAC alongside short-acting GHRH agonists and growth hormone secretagogues to determine the optimal pharmacokinetic profile for their specific assay. The presence or absence of the DAC moiety fundamentally changes receptor kinetics and physiological exposure times across different study models.
For instance, CJC-1295 No DAC (also referred to as Mod GRF 1-29) retains the four amino acid substitutions that resist DPP-IV enzymatic cleavage but lacks the maleimide linker. As a result, CJC-1295 No DAC produces a brief, physiological pulse of GH release lasting approximately 30 to 60 minutes, similar to native Sermorelin. Conversely, researchers combining GHRH analogs with selective ghrelin receptor agonists like Ipamorelin 5mg observe synergistic pulsatile GH release. Understanding these mechanistic differences allows laboratories to select the precise molecular tool necessary for investigating continuous versus episodic somatotropic activation.
The scientific validity of any preclinical experiment depends entirely on the purity and chemical identity of the research compounds used. Contaminants such as truncated peptide sequences, residual synthesis solvents, or bacterial endotoxins can confound experimental data, trigger non-specific cellular inflammatory responses, or cause premature cell death in primary culture models.
At PX1 Research, every production batch of CJC-1295 DAC undergoes rigorous analytical verification prior to distribution. We employ Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC) to establish chemical purity, enforcing a strict minimum baseline of >98%. Electrospray Ionization Mass Spectrometry (ESI-MS) confirms exact molecular mass matching the theoretical formula of C152H252N44O42. Furthermore, chromogenic Limulus Amebocyte Lysate (LAL) assays are conducted to ensure endotoxin levels remain below stringent laboratory thresholds (<0.01 EU/μg), making our material suitable for sensitive downstream applications.
CJC-1295 DAC is supplied as a sterile, lyophilized (freeze-dried) cake or powder to maintain maximum molecular stability during transit and storage. Upon delivery to the research facility, un-reconstituted vials should be stored in a commercial freezer at -20°C (or -80°C for long-term preservation) protected from light and moisture ingress.
When preparing the peptide for in vitro or animal model administration, reconstitution must be performed under aseptic laboratory conditions using sterile bacteriostatic water (0.9% benzyl alcohol) or sterile normal saline, depending on the requirements of the specific research protocol. The diluent should be introduced down the glass wall of the vial to allow gradual dissolution without violent agitation, which can denature the tertiary peptide structure. Once reconstituted, liquid solutions should be kept refrigerated at 2°C to 8°C and utilized within the timeframe defined by the laboratory's stability protocol.
In laboratory research settings, CJC-1295 DAC is evaluated across diverse analytical frameworks. In cell-based bioassays, primary pituitary cell cultures are treated with calculated nanomolar concentrations of the compound to quantify cyclic adenosine monophosphate (cAMP) accumulation and downstream GHRH receptor signaling cascades.
In rodent models, researchers measure circulating GH and IGF-1 levels over multi-day timecourses using enzyme-linked immunosorbent assays (ELISA) or radioimmunoassays (RIA). Additionally, researchers exploring tissue regeneration monitor western blot markers of downstream signaling pathways, including Akt/mTOR and STAT5 phosphorylation. To explore broader metabolic methodologies, scientists can consult our centralized peptides research library for updated literature reviews and analytical framework summaries.
For domestic and international research entities seeking to achetez des peptides de recherche like CJC-1295 DAC, supply chain reliability and transparent compliance are critical procurement criteria.

What does 'DAC' stand for in CJC-1295 DAC?
DAC stands for Drug Affinity Complex. It is a maleimide moiety conjugated to a lysine linker at the C-terminus of the peptide, which allows covalent binding to circulating serum albumin in preclinical models to significantly extend its half-life.
How does CJC-1295 DAC differ from CJC-1295 No DAC (Mod GRF 1-29)?
CJC-1295 DAC contains the maleimide Drug Affinity Complex, enabling it to bind serum albumin and extend its biological half-life to several days in animal models. CJC-1295 No DAC lacks this complex, resulting in a short half-life (approx. 30 minutes) and a brief pulse of GH release.
What is the purity standard for PX1 Research CJC-1295 DAC?
Every lot of CJC-1295 DAC from PX1 Research is verified by independent ISO 17025 accredited third-party laboratories to meet or exceed 98% purity as measured by RP-HPLC, with molecular weight confirmed via ESI-MS.

How should lyophilized CJC-1295 DAC be stored upon arrival?
Lyophilized CJC-1295 DAC should be stored in a freezer at -20°C (or -80°C for extended periods) away from direct light. Once reconstituted, liquid solutions should be kept refrigerated at 2°C to 8°C.
What diluent is recommended for reconstituting CJC-1295 DAC for laboratory use?
