CJC-1295 (No DAC) Handling Guide: Common Mistakes to Avoid
Most handling advice for research peptides is written generically. The practices below are the ones that specifically matter for CJC-1295 (No DAC) — including the mistakes it is unusually easy to make with this compound.
Overview
Room temperature before opening, swirl do not shake, aliquot and refrigerate — never re-freeze the solution.
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
Bench practices for CJC-1295 (No DAC)
- Reach room temperature before opening.
- Swirl to dissolve; do not shake or vortex — foam indicates interfacial stress on the helix.
- Aliquot and refrigerate; never re-freeze reconstituted solution.
The chemistry behind these practices
- Deamidation at Asn/Gln residues over long solution storage.
- Interfacial aggregation of the amphipathic helix if foamed.
- Microbial growth in non-preserved diluent.
Storage summary
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.
