CJC-1295 with DAC Storage & Stability: Cold Chain, Half-Life & Shelf Life
3 min read•Published 2025-07-01•Quality Peptide USA Research
CJC-1295 with DAC is a modified 30-amino-acid GHRH analog incorporating a Drug Affinity Complex (DAC). The DAC chemistry forms a covalent bond with circulating albumin, dramatically extending the peptide's research half-life relative to native GHRH or sermorelin. This guide covers storage & stability for CJC-1295 with DAC — written for laboratory researchers sourcing US-synthesized peptides from Quality Peptide USA.
Lyophilized Shelf Life
Sealed lyophilized CJC-1295 with DAC stored at 2–8°C maintains potency through the expiration date listed on the certificate of analysis (typically 24–36 months from manufacture). Short transit exposure to room temperature during shipping does not meaningfully degrade lyophilized peptide — the vacuum-sealed solid form is highly stable. Once received, refrigerate promptly for long-term storage.
Reconstituted Solution Stability
Lyophilized: 2–8°C. Reconstituted: refrigerate, use within 30 days. Benzyl alcohol in bacteriostatic water provides bacteriostatic protection but does not extend chemical stability indefinitely. Investigators running multi-week protocols should plan their aliquoting strategy in advance.
Reported Research Half-Life
Reported in-vitro / preclinical half-life for CJC-1295 with DAC: ≈ 6–8 days (research models) Half-life depends on study system — plasma, tissue culture media, and intact-animal models all yield different effective windows.
