Mechanism

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.

Mechanism

Hexarelin (Examorelin) is a synthetic hexapeptide GHS-R1a agonist and the most potent synthetic GH secretagogue by peak GH release. It stimulates GH release through both pituitary ghrelin receptors and hypothalamic pathways, with mechanisms involving regulation of GHRH and somatostatin. Hexarelin also demonstrates significant cardiac benefits through activation of cardiac GHS-R1a receptors, protecting against ischemia-reperfusion injury and reducing cardiac fibrosis via the CD36 scavenger receptor pathway.

Standard Dosing

Research indicates 100-200 mcg administered 1-2 times daily via subcutaneous injection.

Timing

On empty stomach, bedtime preferred. Avoid prolonged continuous use due to rapid desensitization.

Cycle Duration

4-8 week cycles maximum, then 4+ week break. Hexarelin desensitizes faster than other GHRPs.

Side Effects

  • Significant cortisol elevation
  • Prolactin increase
  • Water retention
  • Joint pain
  • Rapid desensitization (unique to Hexarelin)

Contraindications

  • Active cancer
  • Cardiac arrhythmias (due to direct cardiac receptor activity)
  • Cushing's syndrome
  • Pregnancy and breastfeeding
