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-2 (Growth Hormone Releasing Peptide-2) is a synthetic hexapeptide GHS-R1a agonist that is the most potent of the GHRP family for GH release. It stimulates pituitary GH secretion through the ghrelin receptor while also modulating hypothalamic GHRH and somatostatin pathways. GHRP-2 increases GH, cortisol, prolactin, and ACTH release, but with less appetite stimulation than GHRP-6. It also has demonstrated anxiolytic properties and sleep-promoting effects.
Research indicates 100-300 mcg administered 1-3 times daily via subcutaneous injection.
On empty stomach, bedtime administration preferred. Wait 2+ hours after last meal.
8-16 week cycles.
