What is CJC-1295 (DAC)?
CJC-1295 (DAC) is a synthetic 30-residue peptide: a modified GRF(1-29) sequence conjugated to a drug affinity complex (DAC). The material is produced by solid-phase peptide synthesis and supplied as a lyophilised powder.
CJC-1295 is classified as a research chemical. It is not an approved medicine and is prohibited in sport by the World Anti-Doping Agency (WADA).
CJC-1295 in the research literature
CJC-1295 appears in the research literature as a modified growth-hormone-releasing factor analogue studied in preclinical contexts. Controlled human data are limited, and no conclusions about effects in humans can be drawn from this body of work.
Form, handling and storage
CJC-1295 (DAC) is supplied as a lyophilised (freeze-dried) powder in a sealed vial. Lyophilised peptides are best stored at -20°C, desiccated and protected from light; long-term stability data are batch-specific and recorded against the batch record.
Batch documentation at Index Peptides
Every released batch of CJC-1295 (DAC) is HPLC purity tested and LC-MS identity confirmed, with the certificate of analysis published on the product page and verifiable by lot number through the batch lookup tool.
Frequently asked questions
Is CJC-1295 (DAC) approved for human use?
No. CJC-1295 is not an approved medicine anywhere in the world. Index Peptides supplies it strictly for in-vitro laboratory research — not for human or animal consumption, administration or any in-vivo use.
What is the CAS number for CJC-1295 (DAC)?
863288-34-0, with a molecular weight of approximately 3647.2 g/mol.
How is each batch verified?
By reversed-phase HPLC for purity and LC-MS for identity (expected vs detected mass). The certificate of analysis is published on the product page, and any batch can be checked by lot number on the verify page.
How do I reconstitute CJC-1295 (DAC)?
Reconstitution is a laboratory handling procedure, not a use instruction. Our documentation-led reconstitution guide covers the mechanics of dissolving lyophilised peptide powders: https://indexpeptides.uk/guides/peptide-reconstitution-guide. Handling is the responsibility of the qualified researcher.
What is the shelf life of CJC-1295 (DAC)?
As supplied (lyophilised powder in a sealed vial), CJC-1295 (DAC) is stored at -20C, desiccated and protected from light. Long-term stability is documented per batch on the certificate of analysis; treat the batch record as the authoritative shelf-life reference for that lot.
What is the difference between the sizes?
The difference is the nominal peptide content per vial. CJC-1295 (DAC) is supplied as 2mg vials. Every format carries the same batch documentation and purity testing.
What does the certificate of analysis show?
Every released batch of CJC-1295 (DAC) is documented with its certificate of analysis: the purity results, identity confirmation and the lot number, published on the product page and checkable through the batch lookup tool. The COA is the authoritative record for that batch.
