02How They Differ
CJC-1295
A growth-hormone-releasing hormone analog studied for pulsatile GH secretion.
CJC-1295 (without DAC) is a modified analog of growth-hormone-releasing hormone (GHRH) fragment 1-29. It acts as a GHRH-receptor agonist on pituitary somatotrophs, studied for its capacity to stimulate growth-hormone release while preserving the natural pulsatile pattern.
CJC-1295 DAC
A GHRH analog with an albumin-binding Drug Affinity Complex for extended half-life.
CJC-1295 with DAC is a modified GHRH(1-29) analog bearing a Drug Affinity Complex (DAC) that binds serum albumin, substantially extending its circulating half-life in research models compared with the no-DAC version.

03Selecting for a Research Model
Because CJC-1295 and CJC-1295 DAC are both endocrine research compounds, they are frequently evaluated against one another. Selection depends entirely on the research question, model system, and endpoints being measured. Both compounds are supplied strictly for in-vitro and laboratory research and are not for human or veterinary use.
