GHRP-2 (10 mg Vial) Dosage Protocol
Research guide for gradual escalation dosing and reconstitution procedures for GHRP-2, a synthetic hexapeptide investigated for growth hormone release stimulation.
Quickstart Highlights
GHRP-2, or pralmorelin, functions as a synthetic hexapeptide that stimulates the ghrelin/GHS receptor on pituitary somatotroph cells to trigger growth hormone release. Operating independently of the typical GH-releasing hormone pathway makes it valuable for research into body composition and recovery support.
- Reconstitute: Add 3.0 mL bacteriostatic water → concentration for daily dosing
- Weekly dosing schedule: 100 mcg → 150 mcg → 200 mcg → 250-300 mcg over 12 weeks
- Easy measuring: Standard U-100 insulin syringe measurement
- Storage: Lyophilized: −20 °C (−4 °F), dry conditions; Reconstituted: 2–8 °C, use within 28 days
Dosing & Reconstitution Guide
Standard Once-Daily Approach (3mL reconstitution)
Daily Subcutaneous Protocol (3 mL reconstitution)
| Duration | Daily Dose | Syringe Units | Volume |
|---|---|---|---|
| Weeks 1–2 | 100 mcg | 3 units | 0.03 mL |
| Weeks 3–4 | 150 mcg | 4.5 units | 0.045 mL |
| Weeks 5–8 | 200 mcg | 6 units | 0.06 mL |
| Weeks 9–12 | 250–300 mcg | 7.5–9 units | 0.075–0.09 mL |
Administration: Single daily subcutaneous injection at bedtime on an empty stomach (2–3 hours after eating).
Reconstitution Steps
- Draw 3.0 mL bacteriostatic water with sterile syringe
- Inject slowly along vial wall; avoid foaming
- Gently swirl/roll until dissolved (do not shake)
- Label with date; refrigerate at 2–8 °C, use within 28 days
Result: Standard reconstitution concentration for daily administration
Storage Guidelines
- Lyophilized: −20 °C (−4 °F), dry/dark conditions
- Reconstituted: 2–8 °C (35.6–46.4 °F); do NOT freeze
- Shelf life: 28 days post-reconstitution
Key Administration Notes
- Rotate injection sites to prevent lipohypertrophy
- Gastrointestinal effects common initially; titration minimizes them
- Document weekly dose, date, and injection site
- Use sterile syringes; dispose in sharps container
- Allow vials to reach room temperature before opening
