GHRP-2 (Growth Hormone–Releasing Peptide-2) is a synthetic peptide that stimulates the pituitary gland to release growth hormone (GH). It works by activating the ghrelin receptor, which also influences hunger and metabolism. GHRP-2 causes a rapid, short-acting pulse of GH rather than sustained elevation. It is commonly used to support muscle recovery, fat loss, and improved sleep. Increased appetite and water retention are common side effects. GHRP-2 is usually administered by subcutaneous injection multiple times per day. It is not approved for medical use and is considered a research compound.
Dosing GHRP-2
HRP-2 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.
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.
