CJC-1295 2mg Peptide Vial

CJC-1295 2mg Peptide Vial is a growth hormone-releasing hormone (GHRH) analog peptide raw material synthesized by our factory, consisting of 29 amino acids with a DAC (Drug Affinity Complex) group coupled to the lysine side chain, sealed in vials in lyophilized form. CJC-1295's sequence is modified based on the 1-29 active fragment of natural GHRH, enhancing anti-enzymatic stability through four amino acid substitutions (Ala2→D-Ala, Gln8→Ala, Ala15→Ala, Leu27→Ala), and coupling a DAC group to lysine at position 29 via a maleimide linker, achieving reversible covalent binding to albumin and extending half-life from minutes to days. Our finished product is white lyophilized powder.

In production of CJC-1295 2mg Peptide Vial, we focus process efforts on efficient DAC group coupling and product separation/purification. DAC coupling reactions require precisely controlled pH and temperature conditions to ensure directional coupling of maleimide groups with lysine side chain amino groups while reducing side reactions. We elevated coupling efficiency by optimizing reaction solvent systems, reactant molar ratios, and reaction time. Coupled products are purified by preparative HPLC to fully separate uncoupled peptides, multi-coupled byproducts from target product. Every batch undergoes HPLC testing, mass spectrometry molecular weight confirmation (verifying successful DAC group coupling), and endotoxin/microbial limit testing before leaving the factory, with COA report. Our product primarily serves research institutions and biotechnology companies for in vitro experiments on growth hormone secretion regulation, metabolic research, and anti-aging.

We have established a full-chain QC system from raw material incoming to finished product outgoing. Raw material stage: incoming inspection of each batch of Fmoc-protected amino acids, resin, and DAC coupling reagents; production stage: QC points at key processes including solid-phase synthesis, cleavage, DAC coupling, purification, with HPLC tracking of intermediates; finished stage: HPLC analysis, mass spectrometry molecular weight confirmation (focus on verifying DAC group coupling status), endotoxin testing, microbial limit testing, and appearance inspection. Each batch comes with COA report, 100% inspection before packaging, customer-designated third-party inspection accepted. Our 35-person QC team is equipped with HPLC, mass spectrometry, UV spectrophotometer and other precision instruments.

We have dedicated after-sales specialists following up on logistics and answering technical questions throughout. Pre-sales: professional foreign trade sales provide product parameters, COA samples, customized quotes, and technical consultation. In-sales: all order details verified, production scheduled, real photos sent at each stage (charging, synthesis, purification, packaging), tracking number provided after shipment with continuous updates. After-sales: goods receipt followed up, technical inquiries responded within 24 hours. If goods arrive damaged, customers provide clear photos/videos of outer packaging and product damage within 48 hours, and we will quickly verify and arrange replacement or partial refund based on actual situation.

Our factory operates in compliance with Chinese environmental regulations, with production waste disposed of properly. The workshop is designed and managed per GMP standards, with core production area at Class 100,000 and key filling/aseptic areas at Class 10,000. The factory has an independent QC laboratory with complete peptide analytical testing capabilities. Each batch can be provided with a COA (Certificate of Analysis) report including batch number, production date, appearance, molecular weight, endotoxin, microbial limits and other key indicators. We continuously improve our quality management system to meet global customers' compliance and traceability requirements.
