02How They Differ
Hexarelin
A growth-hormone-releasing hexapeptide studied for GHS-R and CD36 signaling.
Hexarelin is a synthetic hexapeptide growth-hormone secretagogue. It activates the ghrelin receptor (GHS-R1a) to stimulate growth-hormone release, and is distinctive in the research literature for additional interaction with the CD36 receptor, studied in cardiac-signaling models.
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.

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