What Is CJC-1295 and Ipamorelin? Identity and Research Context
CJC-1295 and Ipamorelin are most often sold together as a blend, which makes them a useful pair to understand together: what each one is as a molecule, the research field they sit in, and what it means to read a certificate of analysis for two peptides in one vial. As with everything we publish, this sticks to identity and research context and does not make claims about what either compound does.
What CJC-1295 and Ipamorelin are
Both are synthetic peptides, and they are chemically distinct. CJC-1295, in the long-acting form used in this blend, is an analog of growth-hormone-releasing hormone (GHRH); its identity is publicly checkable as PubChem CID 91971820, molecular formula C165H269N47O46, average molecular weight about 3,647 g/mol. Ipamorelin is a small five-residue peptide from a different structural family, a growth-hormone secretagogue; its identity is PubChem CID 9831659, CAS 170851-70-4, molecular formula C38H49N9O5, average molecular weight about 711.9 g/mol. We omit a CAS number for CJC-1295 on purpose, because the public CAS assignments for it are inconsistent, and a clean omission is more honest than a number we cannot stand behind.
What research areas are they associated with?
Because CJC-1295 is a GHRH analog and Ipamorelin is a growth-hormone secretagogue, in the scientific literature they are discussed within growth-hormone secretagogue research and the study of the growth-hormone axis, part of the broader fields of endocrinology and metabolic research. That names the research area the molecules sit in; it is not a statement about any effect, result, dose, or use. Naming a field of study is not the same as making a claim, and a research-use description should stay on the first side of that line.
Reading a blend certificate
Because this is two peptides in one vial, its certificate of analysis has to report each component separately. That is why a blend COA shows more than one purity figure, one per peptide, rather than a single blended number: averaging two compounds into one percentage would hide exactly the information you are checking for. When you look up a blend lot on our register, you see each component’s measured purity next to the other, which is the honest way to publish it.
Why we describe it this way
Most pages selling a blend like this lead with what it supposedly does. We do not, for two reasons. These products are sold strictly for laboratory research, so outcome and use claims are not appropriate; and the thing that actually separates one supplier from another is not the copy, it is whether the material is what the label says. That is a documentation question, and we answer it in public: every lot has a third-party certificate you can read before you buy.
Check the lot yourself
You can look up any blend lot on our public register to see each component’s measured purity, read our guide on how to read a COA, or see what >98% purity actually means across every lot we publish. Browse the product itself: CJC-1295 / Ipamorelin.
