Growth Hormone
Vial: 10 mg

GHRP-2 (10 mg Vial)

GHRP-2 (pralmorelin) is a synthetic hexapeptide that potently stimulates growth hormone release by activating ghrelin receptors in the pituitary and hypothalamus. It has been used in clinical research as a diagnostic GH stimulant and in investigative treatment protocols for growth hormone deficiency. This educational protocol presents a once‑daily subcutaneous approach using a practical dilution for clear insulin‑syringe measurements.

Dose
0.1–0.3 mg per injection
Frequency
2–3 times daily
Timing
Morning, post-workout, before bed
Duration
8–12 weeks

Moderate ghrelin activity. Increases appetite. Strong GH release.
