How to Read a CJC-1295 (No DAC) Certificate of Analysis (COA)
A Certificate of Analysis is only useful if you know which number on it matters for the compound in front of you. For CJC-1295 (No DAC), the informative checks are not the same as for a generic short peptide.
Overview
Check the weight matches about 3367 and the trace is clean; peptide content may be listed separately from purity.
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.

What to check on the COA
Confirm the observed mass matches ~3367 Da and that the substitution positions are intact. Check peptide content separately from purity.
Deletion sequences and des-amino related substances from synthesis.

Every batch is third-party tested by HPLC and LC-MS with a published Certificate of Analysis (≥99% purity). Enter a lot number to pull the COA for the exact vial in front of you.
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.
