What the CJC-1295 + Ipamorelin blend is
This product is a two-component mixture in one vial: 5 mg of CJC-1295 and 5 mg of Ipamorelin, co-lyophilized to a stated total of 10 mg. The components come from structurally unrelated families. CJC-1295 is a 29-residue analog of the N-terminal fragment of growth hormone-releasing hormone with four amino acid substitutions, while Ipamorelin is the five-residue amide Aib-His-D-2-Nal-D-Phe-Lys-NH2, a GHRP-type sequence with three non-proteinogenic residues.
What makes the blend a distinct catalog item, rather than two vials in one box, is that its analysis has to resolve and account for both peptides in a single run. The two differ by roughly a factor of five in mass and have nothing in common in sequence, which makes them a comparatively tractable pair to separate.

How the CJC-1295 + Ipamorelin blend is analyzed
A blend chromatogram has two intended main peaks, so the purity statement needs a definition: either the summed area of both components as a share of total area, or each component judged against its own related impurities. The peaks differ in character. Ipamorelin gives a compact peak, strongly retained for its size because of the naphthyl and phenyl rings; CJC-1295 gives the broader peak typical of a 29-residue chain. Reading at about 214 nm counts both on the peptide bond. Equal masses do not mean equal peak areas, since UV response per milligram differs between a five-residue and a 29-residue peptide.
Identity needs one mass confirmation per component: a singly protonated ion near m/z 712 for Ipamorelin, and a deconvoluted multiply charged series for CJC-1295. The independent reverse-phase HPLC result for this blend is published on this page, and because vials carry no lot or batch marking, it is the crimp and cap color that ties a given vial to that result.
Research contexts for the CJC-1295 + Ipamorelin blend
- Multi-component reverse-phase method development and peak-resolution studies
- LC-MS confirmation of mixed short and mid-length peptides within one chromatographic run
- Parallel GHRH-receptor and GHS-R1a binding assays in separate cell-culture systems
- Comparison of per-component and summed purity reporting for peptide mixtures
The blend is offered as an in-vitro research material only and must not be used in humans or animals.
CJC-1295 + Ipamorelin blend questions
Does 5 mg + 5 mg mean the two peaks are the same size?
No. Peak area depends on how strongly each peptide absorbs at the detection wavelength, which differs between the two, so area ratios are not mass ratios unless calibrated against reference standards.
How is each component’s identity confirmed?
By a separate observed mass for each peptide, not a single mass for the vial. Retention time alone can be misassigned in a mixture.
Is the blend’s purity figure comparable to a single-peptide purity?
Only once it is clear whether it is summed or per component. A summed figure can hide a weak minor impurity belonging to one of the two peptides.
