GH secretagogue analogs
CJC-1295 (no DAC) research peptide
CJC-1295 without DAC, also called Modified GRF (1-29), is a 29-residue analog of the N-terminal fragment of growth hormone-releasing hormone. Four amino acid substitutions increase resistance to enzymatic degradation compared with native GRF (1-29). It does not carry the drug affinity complex (DAC) lysine linker found in CJC-1295 with DAC.
For in-vitro laboratory research only. Not for human or veterinary use.

Frequently asked questions
What is CJC-1295 (no DAC)?
CJC-1295 without DAC, also called Modified GRF (1-29), is a 29-residue analog of the N-terminal fragment of growth hormone-releasing hormone. Four amino acid substitutions increase resistance to enzymatic degradation compared with native GRF (1-29). It does not carry the drug affinity complex (DAC) lysine linker found in CJC-1295 with DAC.
How is each CJC-1295 (no DAC) lot tested?
Every lot is tested at an ISO/IEC 17025 accredited third-party laboratory against an eight-assay panel: HPLC-UV purity, quantitative net peptide content, LC-MS identity, appearance, a fentanyl screen, heavy metals by ICP-MS, sterility by PCR, and endotoxin by LAL. The certificate is published before the lot ships.
How do I verify the certificate for my CJC-1295 (no DAC) vial?
Scan the QR code on the vial label to open the certificate for that exact lot, or search the lot number in the North Wall COA library.
Is CJC-1295 (no DAC) for human use?
No. North Wall sells this compound solely for in-vitro laboratory research by qualified researchers aged 21 and over. It is not for human or veterinary use, and North Wall does not provide use, preparation, or dosing guidance.
