Growth Hormone-Releasing Peptide
Weekly Protocol Guide
GHRP-2 Protocol Guide
GHRP-2 is a potent growth hormone-releasing peptide that acts on the ghrelin receptor to stimulate GH release from the pituitary. It produces strong GH release and moderate appetite stimulation. GHRP-2 is considered one of the most effective GHRPs with a favorable side effect profile.
Protocol Overview
- Compound
- GHRP-2 (GHRP-2 (Growth Hormone Releasing Peptide-2))
- Category
- Growth Hormone-Releasing Peptide
- Vial Size
- 5mg (5,000mcg)
- Reconstitution
- 2mL bacteriostatic water (2.5mg/mL)
- Route
- Subcutaneous injection
- Frequency
- 2-3x daily, 5 days/week
Reconstitution Instructions
Using 2mL of bacteriostatic water results in a concentration of 2.5mg/mL. Always use sterile techniques.
Materials Needed
- 5mg GHRP-2 5mg vial (lyophilized powder)
- 2mL bacteriostatic water (sterile, preserved with 0.9% benzyl alcohol)
- Sterile syringe and needle (18-22 gauge for drawing)
- Alcohol swabs
- Clean workspace
Step-by-Step Process
- Preparation: Allow the GHRP-2 5mg vial and bacteriostatic water to reach room temperature. Wipe the rubber stoppers of both vials with an alcohol swab.
- Draw the Water: Using a sterile syringe, draw up exactly 2mL of bacteriostatic water. Expel any air bubbles.
- Inject into Vial: Insert the needle through the rubber stopper at a slight angle, aiming toward the glass wall. Slowly inject the water down the side of the vial to avoid foaming.
- Mix Gently: Remove the needle. Gently swirl or roll the vial between your hands. Do not shake vigorously.
- Check for Clarity: The solution should be clear once fully reconstituted. Do not use if cloudy.

Administration Guidelines
- Administer subcutaneously on an empty stomach (2+ hours after eating) - optimal times: AM fasted, post-workout, before bed
- 100-300mcg per injection, 2-3x daily - strong GH release with moderate appetite stimulation
- Cycle 4-8 weeks on, 2-4 weeks off to prevent receptor desensitization
- Rotate injection sites between abdomen, thigh, and upper arm
- Can be combined with a GHRH analog (e.g., CJC-1295 no DAC) for synergistic effect
- Store reconstituted peptide refrigerated at 36-46F (2-8C)
- Use reconstituted solution within 30 days
- Never freeze reconstituted peptides
- Document administration times and observations
