CJC-1295 / Ipamorelin Research Peptide Blend

Two different molecules circulate under the CJC-1295 name. The original CJC-1295 carries a Drug Affinity Complex — a maleimide linker attached to a lysine side chain that allows covalent binding to albumin. CJC-1295 without DAC, also published as Modified GRF (1-29), is the 29-residue peptide alone, with no such linker.

They differ in composition and mass: the DAC-bearing molecule is recorded in PubChem with the formula C165H269N47O46 and an average mass of approximately 3647 g/mol, which the non-DAC peptide does not share. Documentation, chromatography and mass measurement for one are not interchangeable with the other.

The Vial Drop Labs blend contains the no-DAC form, and it is labelled and documented as CJC-1295 (no DAC) throughout. Where a supplier does not state which form a document describes, the document cannot be compared with one that does.

Ipamorelin is a synthetic pentapeptide, Aib-His-D-2-Nal-D-Phe-Lys-NH2, with the molecular formula C38H49N9O5 and an average molecular weight of approximately 711.9 g/mol (CAS 170851-70-4).

Its structure includes 2-aminoisobutyric acid and two D-configured residues. That matters analytically: D/L isomers are chemically identical by mass, so mass measurement alone cannot confirm stereochemistry. Chromatographic behaviour against a reference standard is the practical identity check for a sequence of this kind.

A single purity number cannot describe a preparation containing two analytes. Third-party reports for this blend resolve the two peptides chromatographically and state an area-percent purity and a measured content for each component against its own 5 mg label claim.

Published reports for Vial Drop Labs material are listed in the Research Documentation portal and are tied to the specific lot they were issued for.

A Certificate of Analysis links a submitted sample to the analytical work performed on it. Current Vial Drop Labs reports are produced by validated HPLC-DAD methodology and answer two separate questions — what the material is, and how much of it is present.

Vial Drop Labs publishes independent analytical reports for tested research materials, with available reports accessible through the Research Documentation portal against the research material and the sample identified on each report. Each analytical report applies only to the sample submitted for analysis and should not be interpreted as testing of every vial or production unit.

Not every report is publicly listed. Where no report has been published for a material, the portal shows none rather than substituting another material's, strength's or batch's results. Documentation is never averaged, combined, or extrapolated between lots.

Current reports are issued by an independent third-party analytical laboratory using validated HPLC-DAD methodology. They report chromatographic purity as area %, content per vial against label claim, and identity as conforming by retention-time and UV/DAD comparison against a reference standard. Current reports do not include mass-spectrometry results.

Vial Drop Labs makes no representation that material is pharmaceutical grade, clinical grade, sterile, safe, or approved by any regulatory authority. Published documentation states exactly what was tested, by which method, and on which date — nothing further should be inferred from it.

Material is supplied lyophilised in a sealed glass vial. General laboratory practice for lyophilised peptides applies: store sealed at -20 °C for long-term storage, protect from light, and minimise exposure to atmospheric moisture.

Allow a cold sealed vial to equilibrate to ambient temperature before opening so that atmospheric moisture does not condense onto the dry cake. Lyophilised peptide material is hygroscopic, and repeated warm/cold cycling of an opened vial is the most common cause of avoidable degradation in a laboratory setting.

Handle as an uncharacterised laboratory chemical using standard laboratory protective equipment and institutional handling procedures.

This material is supplied strictly as a laboratory research chemical. It is not a drug, supplement, cosmetic, food or medical device, and it is not manufactured, labelled or sold for human or animal use of any kind.

Vial Drop Labs does not provide, and cannot provide, dosing, administration, preparation-for-use, therapeutic or clinical guidance. Published information is limited to chemical identity, laboratory handling and analytical documentation.
