MGF (2mg)

Table of Contents

  • Quickstart Highlights

MGF (2mg) protocols focus on this IGF-1 splice variant peptide, known as Mechano Growth Factor, which is studied for its potential role in muscle repair, satellite cell activation, and localized tissue regeneration following mechanical stress or training. MGF may support enhanced recovery and muscle tissue remodeling. This guide outlines a subcutaneous administration approach optimized for the 2 mg vial format.

  • Reconstitute: Add 1.0 mL bacteriostatic water → 2 mg/mL concentration
  • Typical dosing range: 200–400 mcg per dose (subcutaneous or localized use in research settings)
  • Easy measuring: At 2 mg/mL, 1 unit = 0.01 mL = 20 mcg on a U-100 insulin syringe
  • Storage: Lyophilized: store at −20 °C; after reconstitution, refrigerate at 2–8 °C and use within 10–14 days
  • Protocol Overview

Concise summary of the peptide regimen.

  • Goal: Support muscle recovery, repair, and satellite cell activation after training
  • Schedule: Administered post-exercise or on training days in research protocols
  • Dose Range: 200–400 mcg per injection
  • Dosing Protocol

Suggested approach for the 2 mg vial format.

  • Start: 200 mcg per dose to assess tolerance
  • Target: 200–400 mcg per dose
  • Frequency: Typically post-workout or 3–4 times per week in research settings
  • Vial Duration: One 2 mg vial lasts approximately 5–10 doses, depending on usage
  • Timing: Best used immediately after training sessions when muscle signaling is elevated
  • Mechanism of Action

Mechano Growth Factor (MGF) is a splice variant of the IGF-1 gene that is expressed in response to mechanical stress, such as resistance training or muscle damage. Unlike systemic IGF-1, MGF is believed to act locally within muscle tissue.

It activates satellite cells—muscle stem cells responsible for repair and growth—and may promote muscle fiber repair and hypertrophy. MGF is thought to initiate early-stage regeneration processes, making it distinct from other growth-related peptides that act more systemically. Preclinical research suggests it plays a key role in muscle adaptation following resistance exercise.
