About GHRP-2
Synthetic hexapeptide that stimulates pulsatile growth hormone release from the anterior pituitary by acting on the ghrelin receptor (GHSR-1a). Commonly stacked with GHRH analogs such as CJC-1295 or Sermorelin to amplify GH output synergistically.
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

Under clinical review
Being verified by our medical team before we display contraindications for this peptide.
GHRP-2 stimulates GH and cortisol release. Research protocols measure IGF-1 for GH axis response and baseline cortisol given the compound's adrenal stimulation. Glucose markers are standard given GH's effect on insulin sensitivity.

Corticosteroids
Research notes that GHRP-2 stimulates cortisol and ACTH release via the HPA axis. Combined use with corticosteroid medications may affect glucocorticoid regulation. Consult your prescriber before combining.
