What is GHRP-2?
GHRP-2 (GHRP-2 (Growth Hormone Releasing Peptide-2)) is a research peptide in the growth hormone category. With a half-life of approximately ~1.5 hours, it has become an important tool in peptide research.
This peptide has been the subject of growing research interest for its potential applications in growth hormone protocols. Researchers value it for its specificity and well-characterized pharmacological profile.
All research with GHRP-2 should follow proper laboratory protocols and institutional guidelines.

Reconstitution Guide
Materials Needed
- GHRP-2 10mg lyophilized vial
- Bacteriostatic water (BAC water)
- Insulin syringes (U-100, 29-31 gauge)
- Alcohol swabs
- Sharps container
Step-by-Step Instructions
-
Prepare your workspace — Clean your work area and gather all materials. Wash hands thoroughly.
-
Clean the vial stoppers — Wipe the GHRP-2 vial stopper and BAC water vial with alcohol swabs. Allow to dry completely.
-
Draw the BAC water — Using a sterile syringe, draw 3mL of bacteriostatic water.
-
Add water to peptide vial — Insert the needle into the GHRP-2 vial and slowly inject the BAC water down the inside wall of the vial. Do not spray directly onto the powder.
-
Allow to dissolve — GHRP-2 may take 5-10 minutes to fully dissolve. Gently swirl occasionally — never shake vigorously.
-
Verify dissolution — The solution should be completely clear and colorless. If cloudy or particles remain, continue gentle swirling.
-
Label and store — Write the reconstitution date on the vial. Store in refrigerator immediately.
Dosage Protocol
Concentration Calculations
With 10mg peptide in 3mL BAC water:
- Resulting Concentration: 3.33mg/mL = 3330mcg/mL
- Per unit (U-100 syringe): 33.3mcg per unit
Common Dose Calculations
| Desired Dose | Draw Volume | Syringe Units |
|---|---|---|
| 100mcg | 0.03mL | 3 units |
| 200mcg | 0.06mL | 6 units |
| 300mcg | 0.09mL | 9 units |
| 500mcg | 0.15mL | 15 units |
| 1000mcg | 0.30mL | 30 units |
Injection Guide
Subcutaneous Administration
- Clean the injection site with an alcohol swab
- Pinch a fold of skin (abdomen, thigh, or upper arm)
- Insert needle at 90° angle
- Inject slowly and steadily
- Wait 5-10 seconds before withdrawing needle
- Apply light pressure if needed — do not rub
Site Rotation
Rotate between these areas:
- Abdomen (2+ inches from navel) — most common
- Outer thigh (front/outer area)
- Back of upper arm

Safety & Handling
- Use sterile technique for all preparations
- Never reuse needles or syringes
- Dispose of sharps properly in designated containers
- Store away from children and unauthorized persons
- GHRP-2 is for research purposes only
Sourcing for Research
Source from verified suppliers that provide third-party testing and certificates of analysis (COA) for each batch. Compare purity documentation, shipping conditions, and batch traceability before purchasing research materials.
