CJC-1295 is one of the most studied compounds in growth hormone research, and it is frequently mentioned alongside ipamorelin. Here is a clear look at what it actually is and what to check before sourcing it.
What CJC-1295 is
CJC-1295 is a synthetic analog of growth hormone releasing hormone, usually shortened to GHRH. According to PubMed, it was studied as a long-acting GHRH analog. In that research it produced sustained increases in growth hormone and IGF-1 and had a much longer half-life than the natural hormone, with effects measured over several days after a single dose (Teichman et al., 2005, DOI).
Why the long-acting part matters in research
Natural GHRH breaks down quickly, which limits how it can be studied. The reason CJC-1295 drew so much research interest is that it lasts far longer, which is what the published work focused on. That extended duration is the defining feature of the compound and the main reason it shows up so often in growth hormone literature.
How it relates to ipamorelin
CJC-1295 acts on the GHRH receptor pathway. Ipamorelin acts on a different pathway, the ghrelin or GHRP receptor. Because the two work through separate routes, they are often studied together, which is why a CJC-1295 and Ipamorelin blend exists as a single research product.

Sourcing CJC-1295
With any in-demand compound, documentation is what protects you. Look for a per batch Certificate of Analysis you can see before you buy, HPLC purity on the specific lot, mass spectrometry confirmation, and a lot number tied to your vial.
Peptide Hackers carries CJC-1295, along with the CJC-1295 and Ipamorelin blend, with that documentation on every batch. For researchers in the Los Angeles and Orange County areas, you can order online and pick up the same day in person, with shipping available if you prefer delivery.
