How Long Does CJC-1295 (No DAC) Last? Shelf Life & Stability
"Stable" is meaningless without saying stable against what. CJC-1295 (No DAC) has its own set of degradation routes, and they determine which storage precautions actually matter for it.
Overview
The four built-in tweaks help it survive the enzyme that destroys natural GHRH in minutes, but that is not the same as lasting forever once mixed — refrigerate and use within a few weeks.
What CJC-1295 (No DAC) actually is
A trimmed, stabilised piece of the natural growth-hormone-releasing hormone that nudges the pituitary to release GH in short, natural pulses. Leaving off the DAC part keeps it short-acting, which is what researchers study it for. Often searched as Modified GRF 1-29.
Supplied for laboratory research use only — not for human or animal use.
Third-party tested by HPLC and LC-MS, ≥99% purity, with a Certificate of Analysis on every order. Ships across Canada.
Technical detail below
Degradation routes specific to CJC-1295 (No DAC)
- Deamidation at Asn/Gln residues over long solution storage.
- Interfacial aggregation of the amphipathic helix if foamed.
- Microbial growth in non-preserved diluent.
The four engineered substitutions specifically blunt the DPP-4 cleavage that destroys native GHRH within minutes — that resistance is a design feature, not a storage guarantee.
Freeze–thaw tolerance
Aliquot on first reconstitution; avoid re-freezing the solution.
How storage addresses these routes
Practical window once reconstituted: 2-3 weeks at 2-8 °C.
Full CJC-1295 (No DAC) storage conditionsWhat CJC-1295 (No DAC) is studied for
Studied for prompting growth-hormone release in short, physiological pulses via the GHRH receptor.
The four substitutions are studied for extending the molecule beyond the minutes-long survival of native GHRH.
Frequently studied alongside ghrelin-receptor secretagogues such as Ipamorelin, which recruit a second GH-release pathway.
