GHRP-2 (5 mg Vial)
GHRP-2 (Growth Hormone-Releasing Peptide-2) is a synthetic hexapeptide that stimulates potent, dose-dependent growth hormone release by activating ghrelin receptors. Clinical studies predominantly employ once-daily subcutaneous administration to elicit robust pulsatile GH release while minimizing receptor desensitization. This educational protocol presents a practical gradual titration approach with clear insulin-syringe measurements.
- Dose
- 0.1–0.3 mg per injection
- Frequency

Moderate ghrelin activity. Increases appetite. Strong GH release.
