About GHRP-6
Ghrelin receptor agonist; stimulates pituitary GH release and increases appetite via hypothalamic ghrelin pathways
About IGF-2
Binds IGF-1R and insulin receptor variant A; promotes anabolic signaling in muscle and fat; activates PI3K/Akt/mTOR pathway; different receptor binding profile than IGF-1

GHRP-6
Under clinical review
Being verified by our medical team before we display contraindications for this peptide.
GHRP-6 produces stronger cortisol and prolactin stimulation than selective GH peptides. Research protocols measure IGF-1 for GH axis response and baseline cortisol. Glucose markers are standard given GH's effect on insulin sensitivity.

Being verified by our medical team before we display contraindications for this peptide.
GHRP-6
Corticosteroids
Research notes that GHRP-6 stimulates cortisol and ACTH release via the HPA axis. Combined use with corticosteroid medications may affect glucocorticoid regulation. Consult your prescriber before combining.
