GHRP-6 5mg | Growth Hormone Releasing Peptide | Endocrine & GH Axis Research | West Lab Chemicals
Product Overview
GHRP-6 (Growth Hormone Releasing Peptide-6) is a synthetic hexapeptide belonging to the growth hormone secretagogue (GHS) family. It functions as a ghrelin receptor (GHS-R1a) agonist, stimulating the pituitary gland to release growth hormone (GH) in a pulsatile and physiologic pattern.
At West Lab Chemicals, we provide GHRP-6 5mg (Research Grade) with ≥99% purity (HPLC & MS verified), manufactured under GMP-certified laboratory conditions to ensure maximum purity, stability, and reproducibility.
This peptide is commonly used in endocrine, metabolic, and cellular regeneration research to explore GH regulation, IGF-1 activity, and appetite control mechanisms.
What is GHRP-6?
Growth Hormone Releasing Peptide-6 (GHRP-6) is part of the GH secretagogue family, designed to mimic the activity of ghrelin, the body’s natural growth hormone–releasing hormone.
It binds specifically to ghrelin receptors (GHS-R1a) in the hypothalamus and pituitary, stimulating growth hormone secretion independent of GHRH.
Mechanism of Action:
-
Activates ghrelin (GHS-R1a) receptors
-
Triggers GH release from the pituitary gland
-
Increases IGF-1 synthesis (in research models)
-
Promotes protein synthesis, tissue recovery, and metabolic regulation
