Overview
GHRP-2 is a growth hormone secretagogue that triggers a strong GH pulse by binding the ghrelin receptor. It’s a workhorse GH peptide — often stacked with a GHRH analog like CJC-1295 or Sermorelin for a bigger, broader pulse.
Preparation
Recon: 5 mg vial + 3 mL BAC (1.67 mg/mL).
Protocol
| Period | Dose | Units (@ 1.67 mg/mL) | Frequency |
|---|---|---|---|
| Weeks 1–2 | 100 mcg | 6 units (0.06 mL) | 1x/day |
| Weeks 3–4 | 150 mcg | 9 units (0.09 mL) | 1x/day |
| Weeks 5–16 | 200 mcg | 12 units (0.12 mL) | 1x/day |
Cycle
8–16 week cycles. Once-daily dosing avoids the receptor desensitization you get from frequent pulsing. Evening dosing on an empty stomach rides the natural nocturnal GH wave.
