GHRP-2 (5mg)

Table of Contents

  • Quickstart Highlights

GHRP-2 (5mg) protocols focus on this synthetic growth hormone-releasing peptide (GHRP) studied for its ability to stimulate natural growth hormone (GH) release via ghrelin receptor activation. It may support muscle growth, fat metabolism, recovery, and improved sleep quality. This guide outlines a subcutaneous administration approach optimized for the 5 mg vial format.

  • Reconstitute: Add 1.0 mL bacteriostatic water → 5 mg/mL concentration
  • Typical daily range: 100–300 mcg per dose, 1–3 times daily (subcutaneous)
  • Easy measuring: At 5 mg/mL, 1 unit = 0.01 mL = 50 mcg (0.05 mg) on a U-100 insulin syringe
  • Storage: Lyophilized: store at −20 °C; after reconstitution, refrigerate at 2–8 °C and use within 2–4 weeks
  • Protocol Overview

Concise summary of the subcutaneous regimen.

  • Goal: Stimulate endogenous growth hormone release for recovery and metabolic support
  • Schedule: 1–3 injections daily, often spaced throughout the day
  • Dose Range: 100–300 mcg per administration
  • Dosing Protocol

Suggested approach for the 5 mg vial format.

  • Start: 100 mcg once or twice daily to assess tolerance
  • Target: 200–300 mcg per dose, up to 2–3 times daily
  • Frequency: 1–3 times per day (subcutaneous)
  • Vial Duration: One 5 mg vial lasts approximately 8–25 days, depending on dosing
  • Timing: Commonly used before meals or before sleep; avoid dosing immediately after eating for optimal GH pulse
  • Mechanism of Action

GHRP-2 is a synthetic peptide that binds to the ghrelin receptor (growth hormone secretagogue receptor, GHS-R) in the pituitary and hypothalamus. This stimulates pulsatile release of growth hormone independent of growth hormone-releasing hormone (GHRH).

By increasing GH levels, it may subsequently elevate IGF-1 (Insulin-like Growth Factor-1), which plays a role in muscle growth, tissue repair, and metabolism. GHRP-2 is also known for its potential effect on appetite stimulation due to its interaction with ghrelin pathways.

  • Potential Benefits & Side Effects

Observations based on preclinical and early-stage research.

Potential Benefits:

  • May increase natural growth hormone and IGF-1 levels
  • May support muscle growth and fat loss
  • May improve recovery, sleep quality, and overall performance
  • May stimulate appetite (useful in some contexts)

Possible Side Effects:

  • Increased hunger (common due to ghrelin activation)
  • Water retention or mild bloating
  • Injection-site irritation
  • Possible prolactin or cortisol elevation in higher doses
  • Long-term safety not fully established; remains investigational
