How to Store CJC-1295 (No DAC): Temperature, Shelf Life & Handling
Storage requirements for CJC-1295 (No DAC) follow from what the molecule actually is — ghrh(1-29) tetra-substituted analogue (dac-free). The conditions below reflect that chemistry rather than generic peptide guidance.
Overview
Freezer sealed, fridge once mixed, and do not re-freeze the liquid. Use within two to three 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.

Storage conditions for CJC-1295 (No DAC)
Why these conditions, specifically
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.
The main route to be aware of: deamidation at Asn/Gln residues over long solution storage.
All 3 degradation routes for CJC-1295 (No DAC)Freeze–thaw
Aliquot on first reconstitution; avoid re-freezing the solution.
What 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.
