Hexarelin (5mg)

Table of Contents

  • Quickstart Highlights

Hexarelin (5mg) protocols center on this synthetic hexapeptide classified as a growth hormone secretagogue, known for stimulating endogenous growth hormone (GH) release via the ghrelin receptor (GHS-R1a). It has been studied for its potential effects on muscle recovery, body composition, and cardiovascular support. 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 dosing range: 100–300 mcg once or twice 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: Support natural growth hormone secretion for recovery and metabolic benefits
  • Schedule: Daily injections, typically 1–2 times per day
  • Dose Range: 100–300 mcg per dose
  • Dosing Protocol

Suggested approach for the 5 mg vial format.

  • Start: 100 mcg once daily to assess tolerance
  • Target: 100–300 mcg once or twice daily
  • Frequency: 1–2 times per day (subcutaneous)
  • Vial Duration: One 5 mg vial lasts approximately 8–50 days, depending on dose
  • Timing: Commonly used in the morning and/or before sleep
  • Mechanism of Action

Hexarelin is a potent growth hormone secretagogue that binds to the ghrelin receptor (GHS-R1a) in the pituitary gland and hypothalamus. This binding stimulates pulsatile release of endogenous growth hormone without directly supplying exogenous GH.

Increased GH secretion may support downstream effects such as elevated IGF-1 production, enhanced protein synthesis, improved fat metabolism, and tissue repair processes. Unlike some other secretagogues, Hexarelin has also been studied for potential cardioprotective effects in preclinical models, including support for cardiac contractility and reduced ischemic damage.

  • Potential Benefits & Side Effects

Observations based on preclinical and early research literature.

Potential Benefits:

  • May increase endogenous growth hormone secretion
  • May support muscle recovery and lean body composition
  • May assist fat metabolism and energy utilization
  • Potential cardioprotective effects observed in animal studies

Possible Side Effects:

  • Temporary water retention
  • Increased appetite in some users
  • Mild tingling or flushing
  • Possible desensitization with prolonged continuous use
  • Long-term human safety data are limited; it remains investigational
