Description
GHRP-2 Dosage Chart
GHRP-2 is dosed at 100 mcg–200 mcg daily via subcutaneous injection in educational protocols. A 5 mg vial reconstituted with bacteriostatic water yields about 1.67 mg/mL. This information is for research and educational use only.
- Reconstitute: Add 3.0 mL bacteriostatic water → ~1.67 mg/mL concentration.
- Typical daily range: 100–300 mcg once daily subcutaneously.
- Easy measuring: At 1.67 mg/mL, 1 unit = 0.01 mL ≈ 16.7 mcg on a U-100 insulin syringe.
- Storage: Lyophilized: freeze at −20 °C (−4 °F); after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F).
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.

Dosing & Reconstitution Guide
Educational guide for reconstitution and daily dosing
Standard / Gradual Approach (3 mL = ~1.67 mg/mL)
| Week | Daily Dose (mcg) | Units (per injection) (mL) |
|---|---|---|
| Weeks 1–2 | 100 mcg | 6 units (0.06 mL) |
| Weeks 3–4 | 150 mcg | 9 units (0.09 mL) |
| Weeks 5–8 | 200 mcg | 12 units (0.12 mL) |
| Weeks 9–12 | 200 mcg | 12 units (0.12 mL) |
| Weeks 13–16 | 200 mcg | 12 units (0.12 mL) |
Frequency: Inject once daily subcutaneously. This once-daily schedule balances efficacy with receptor recovery time, avoiding the rapid attenuation seen with frequent dosing. Administering in the evening may capitalize on nocturnal GH rhythms. For ≤10-unit (≤0.10 mL) administrations, consider 30- or 50-unit insulin syringes for improved readability.
Reconstitution Steps
- Draw 3.0 mL bacteriostatic water with a sterile syringe.
- Inject slowly down the vial wall; avoid foaming.
- Gently swirl or roll until completely dissolved (do not shake).
- Label and refrigerate at 2–8 °C (35.6–46.4 °F), protected from light.
