Oral-stable BPC-157, typically formulated as the arginate salt, retains the same mechanism as standard BPC-157 — promoting angiogenesis via VEGFR2/PI3K/Akt/eNOS and Src-Caveolin-1-eNOS pathways, enhancing nitric oxide production, and stimulating tendon fibroblast growth and collagen formation. The arginate salt provides a protective buffer against gastric acid degradation, maintaining peptide integrity across a wider pH range. BPC-157 demonstrates remarkable native stability in human gastric juice (24+ hours), and the arginate form reportedly achieves 7-fold greater oral bioavailability compared to the acetate salt in preclinical studies.

GHRP-6 (Growth Hormone Releasing Peptide-6) is a synthetic hexapeptide that stimulates GH release through activation of the growth hormone secretagogue receptor (GHS-R1a/ghrelin receptor) on pituitary somatotrophs. It acts via dual sites — pituitary and hypothalamic — possibly involving regulatory factors beyond GHRH and somatostatin. GHRP-6 also stimulates ghrelin-mediated appetite signaling, increases cortisol and prolactin release, and has demonstrated cytoprotective properties including cardioprotection.
Research indicates 100-300 mcg administered 1-3 times daily via subcutaneous injection.
