5mg Lyophilized Peptide
A growth-hormone-releasing hormone (GHRH) analog studied in endocrine research.
A growth-hormone-releasing hormone (GHRH) analog studied in endocrine research. Animal studies have examined GH and IGF-1 secretion and related physiologic endpoints (e.g., bone density, protein synthesis, fat metabolism). Findings are specific to the models described.

CJC-1295 is a modified version of the first 29 amino acids of GHRH, which means it is chemically similar to other GHRH analogues, like Sermorelin. It is most similar to modified GRF (1-29), but the two peptides are not identical. A great deal of confusion arises because of the similarities between these peptides and because CJC-1295 was originally created with an added chemical compound called the drug affinity complex (DAC).
DAC is added to the molecule, with the help of a lysine linker, to protect the peptide while it circulates in the blood stream. By allowing peptides to bind to the common blood protein albumin, DAC helps to ensure that the half-life of CJC-1295 is much longer than similar molecules like GRF (1-29).

Originally, ConjuChem Biotechnologies, the developer of DAC, referred to the molecule containing DAC as simply CJC-1295. Confusion arose, however, because the peptide was also being offered without DAC. To avoid confusion, CJC-1295 that contains DAC is called CJC-1295-DAC and when it does not contain DAC it is referred to as CJC-1295 or CJC-1295-no DAC.
CJC-1295 is a growth hormone secretagogue designed to have a long plasma half-life and to preserve the physiologic patterns inherent in the GH axis. On both accounts, the molecule has been a success. CJC-1295 has experienced limited interest in research settings due to the advent of a number of similar molecules and because of the proprietary nature of the molecule’s structure.
