CJC-1295 / Ipamorelin Blend Testing & Verification
Independent, third-party analysis of CJC-1295 / Ipamorelin blend vials by RP-HPLC-UV — a 29-residue GHRH analog and a pentapeptide in one vial, each resolved and reported separately on one certificate.
What CJC-1295 / Ipamorelin is
CJC-1295 / Ipamorelin is the most common two-active blend on the research market, most often labelled as a 5/5 mg split. The CJC-1295 in it is almost always the no-DAC form — the 29-residue modified GRF(1-29) — rather than CJC-1295 with DAC, which carries an additional lysine-linked maleimide group and is a different molecule with different retention. Ipamorelin is a five-residue peptide that elutes far earlier. The two resolve cleanly under our method and each is quantified against its own certified reference standard; a single purity figure for the vial would be meaningless. Our certificate leads with the name on your label and prints the two actives beneath it, each with its own results row — and it says which CJC-1295 the identity was judged against.
Why get your CJC-1295 / Ipamorelin independently tested
- DAC or no DAC: the two CJC-1295 forms are different molecules sold under one name. Declaring which one is on your label lets identity be judged against the right standard; a vial that matches the other form is reported as not conforming.
- Split verification: each active gets its own identity, purity, and content line, so a vial that is short on Ipamorelin — the cheaper, easier-to-skip component — cannot hide behind a healthy CJC-1295 peak.
- Content on two small claims: 5 mg each is where fill error is a large share of the label. The per-active net-peptide assay reports each compound's measured milligrams against its declared share.
- Synthesis-related impurities on the long active: a 29-residue sequence accumulates deletion and truncation species near the parent peak. Per-active purity as area percent reports how clean each compound is.
What we measure on CJC-1295 / Ipamorelin
A CJC-1295 / Ipamorelin certificate reports, for EACH of the two actives, by reversed-phase HPLC with diode-array detection at 214 nm: identity (retention-time and UV-spectral match against that compound's own certified reference standard, with the CJC-1295 form stated), chromatographic purity as area percent, content in milligrams per vial, and retention time — one vial, one certificate, one verification code, two fully reported compounds. Appearance and optional pH are reported at the vial level.
Every result is issued as a certificate of analysis you — or anyone you forward it to — can verify cryptographically. Reporting identity, purity, and milligram content is the point: a vial can be pure and still underfilled, so we report all three. More on purity vs. net-peptide content and how to read a peptide COA.
Our scope — stated plainly
Testing is RP-HPLC-UV against certified reference standards for each declared active — not mass spectrometry. The certificate reports the actives declared on your label; it does not de-novo identify unlabelled compounds. KMD Analytical is an independent laboratory; we do not perform sterility, endotoxin, heavy-metal, or residual-solvent testing.
KMD is an independent RP-HPLC-UV lab. We do not run LC-MS / mass-spec, sterility, endotoxin, or heavy-metal testing. If your job needs a capability we don't have, we'll say so.
CJC-1295 / Ipamorelin testing — FAQ
Is my CJC-1295 the DAC or no-DAC form?
Ask your supplier — most blends with Ipamorelin use the no-DAC form (Mod GRF 1-29), which is what our preset assumes. If your label says 'with DAC', put that on the order form and identity is judged against the DAC standard instead. The certificate states which was used.
Can such a small peptide as Ipamorelin be resolved next to CJC-1295?
Yes. Ipamorelin elutes well ahead of CJC-1295 under our method; each is identified against its own reference standard and quantified on its own calibration.
My split isn't 5/5 — can you still test it?
Yes. The 5/5 split is only the most common label; the blend preset pre-fills it when you order and you edit it to match your vial. Each active is verified against whatever your label declares.
Do I get one certificate or two?
One. A blend vial produces a single certificate with one verification code, on which each declared active has its own identity, purity, content, and retention-time row.
