MGF (Mechano Growth Factor)

How It Works

MGF (IGF-1Ec) is produced by muscle cells in response to mechanical damage from exercise. It activates satellite cells — dormant muscle stem cells that fuse with existing muscle fibers to repair damage and add new nuclei for growth. Native MGF has a very short half-life (minutes), so the PEGylated form (PEG-MGF) extends activity to several days. Unlike IGF-1 LR3, MGF specifically targets local muscle repair.

Key Research Findings

• Activates satellite cells for local muscle repair and hyperplasia
• Produced naturally in muscle tissue after resistance exercise
• PEG-MGF extends the half-life from minutes to several days
• May improve recovery from muscle injuries when used with rehabilitation

Reconstitution Guide

Follow these steps to properly reconstitute MGF (Mechano Growth Factor) for research use:

• Step 1: Swab the tops of both the peptide vial and bacteriostatic water vial with alcohol.
• Step 2: Draw your desired amount of BAC water (commonly 1–2 mL) into an insulin syringe.
• Step 3: Inject the water slowly into the peptide vial, aiming at the glass wall — not directly onto the powder.
• Step 4: Swirl the vial gently until fully dissolved — never shake.
• Step 5: Refrigerate at 36–46°F (2–8°C). Use within 4–6 weeks.

Use the dosing calculator to calculate your exact concentration (mcg per unit) and how many units to draw on your syringe.
