GHRP-2 (5 mg Vial) Dosage Protocol
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[1]. Clinical studies predominantly employ once-daily subcutaneous administration to elicit robust pulsatile GH release while minimizing receptor desensitization[2][3]. This educational protocol presents a practical gradual titration approach with clear insulin-syringe measurements.

Standard / Gradual Approach (3 mL = ~1.67 mg/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
Weeks 13–16
Frequency: Inject once daily subcutaneously. This once-daily schedule balances efficacy with receptor recovery time, avoiding the rapid attenuation seen with frequent dosing[3]. 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.
Supplies Needed
Plan based on an 8–16 week daily protocol with gradual titration.
Peptide Vials (GHRP-2, 5 mg each):
8 weeks ≈ 2 vials
12 weeks ≈ 4 vials
16 weeks ≈ 5 vials
Insulin Syringes (U-100):
Per week: 7 syringes (1/day)
8 weeks: 56 syringes
12 weeks: 84 syringes
16 weeks: 112 syringes
Bacteriostatic Water (10 mL bottles): Use ~3.0 mL per vial for reconstitution.
8 weeks (2 vials): 6 mL → 1 × 10 mL bottle
12 weeks (4 vials): 12 mL → 2 × 10 mL bottles
16 weeks (5 vials): 15 mL → 2 × 10 mL bottles
Alcohol Swabs: One for the vial stopper + one for the injection site each day.
Per week: 14 swabs (2/day)
8 weeks: 112 swabs → recommend 2 × 100-count boxes
12 weeks: 168 swabs → recommend 2 × 100-count boxes
16 weeks: 224 swabs → recommend 3 × 100-count boxes
