02Mechanism of Action
Sermorelin corresponds to the first 29 amino acids of growth-hormone-releasing hormone — the minimal fully active GHRH fragment. It is studied as a GHRH-receptor agonist that stimulates endogenous growth-hormone synthesis and release from the anterior pituitary.
As a GHRH analog it is a common reference tool in GH-axis and pituitary-secretion research.

05FAQ
What is Sermorelin?
Sermorelin is a GHRH(1-29) analog — the active fragment of growth-hormone-releasing hormone — studied for pituitary GH stimulation in research models. It is a research-use-only compound.
How does Sermorelin compare to CJC-1295?
Both are GHRH-receptor agonists; Sermorelin is the native GHRH(1-29) sequence, while CJC-1295 carries stabilizing modifications studied for extended activity.
What is Sermorelin's molecular weight?
Sermorelin has an approximate molecular weight of 3,357.9 g/mol and CAS number 86168-78-7.
How should Sermorelin be stored?
Sermorelin ships lyophilized and should be handled per standard research-peptide practice — kept cold, protected from light and moisture, and reconstituted only for laboratory use. Cold-chain handling is used where required. For research use only.
Is Sermorelin approved for human use?
No. Sermorelin is sold strictly for laboratory research use only and is not a drug or supplement. It is not approved for human or veterinary use or consumption.
How is Sermorelin tested at Ethos Bio?
Every Sermorelin lot is independently verified by MZ Biolabs, a third-party analytical laboratory in Arizona, on a five-point panel — RP-HPLC purity, HPLC-MS identity, endotoxin (LAL), heavy metals, and sterility. A lot-specific certificate of analysis ships with the vial. See How We Test for the full methodology.
