02How They Differ
GHRP-2
A growth-hormone-releasing hexapeptide studied for GHS-R agonism.
GHRP-2 (pralmorelin) is a synthetic hexapeptide that acts as an agonist at the growth-hormone secretagogue receptor (GHS-R1a), stimulating growth-hormone release from the pituitary in research models.
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.

03Selecting for a Research Model
Because GHRP-2 and Hexarelin 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.
Whichever you select, every Ethos Bio lot is verified the same way — a five-point independent panel with a batch-specific Certificate of Analysis. See how we test →
