The components

The mixture contains two separate peptides. A mixture has no single molecular formula, so each component is described by its own PubChem record.

What is the CJC-1295 (no DAC) and Ipamorelin mixture?

The CJC-1295 (no DAC) and Ipamorelin mixture is a mixture of two separate synthetic peptides in one lyophilized solid.

CJC-1295 (no DAC), also known as Mod GRF 1-29, is a synthetic linear peptide of 29 amino acids with an amidated C-terminus and a D-alanine at position 2. It is catalogued under CAS 863288-34-0 and PubChem CID 56841945, with the molecular formula C152H252N44O42 and a molecular weight of 3367.9 g/mol.1

Ipamorelin is a synthetic pentapeptide with an amidated C-terminus, H-Aib-His-D-2-Nal-D-Phe-Lys-NH2. It is catalogued under CAS 170851-70-4 and PubChem CID 9831659, with the molecular formula C38H49N9O5 and a molecular weight of 711.9 g/mol.2

The components are not chemically bonded to each other. The material described on this page is intended as a laboratory reagent.

Handling

The CJC-1295 (no DAC) and Ipamorelin mixture is a dry solid as received in the laboratory. General handling guidance for lyophilized peptides applies.3

  • Allow the sealed container to reach room temperature before opening, so moisture does not condense on the solid.3
  • Keep the solid dry and away from bright light. Moisture lowers long-term stability.3
  • Avoid repeated freezing and thawing.3

How each lot is tested

Each lot in the My Oasis Peptides catalogue is tested by an independent third-party laboratory.4 The CJC-1295 (no DAC) and Ipamorelin mixture certificate page names the testing laboratories and lists each lot's purity, net content and test date. Three measurements are reported.

Identity

Mass spectrometry

Identity by mass spectrometry is reported for each lot as tested. For reference, the calculated monoisotopic masses are 3365.89 Da for CJC-1295 (no DAC)1 and 711.39 Da for Ipamorelin.2

A matching mass is consistent with the expected composition. It does not confirm the order of residues.

Purity

High-performance liquid chromatography (HPLC)

Separates the components from synthesis-related impurities. Purity is reported for the lot as a share of the total detected signal.

Reported per lot on the Certificate of Analysis.

Quantity

Net content

Measures the mass of material actually present in the sample tested.

Reported per lot on the Certificate of Analysis.

Technical notes

What does the Certificate of Analysis report for a mixture?

The certificate page lists each lot with identity by mass spectrometry, purity by HPLC, net content and test date. Values are reported for the mixture as tested.

Why are formulas given for each component?

A mixture has no single molecular formula or weight. Each component is described by its own PubChem record.

Why is the material freeze-dried?

Peptides are most stable as dry solids. Moisture reduces long-term stability, so the material is lyophilized and kept sealed until use in the laboratory.

CJC-1295 (no DAC) and Ipamorelin mixture lot certificates

Each listed CJC-1295 (no DAC) and Ipamorelin mixture lot has its own certificate covering identity, purity and net content.
