PEG-MGF is a modified, long-acting version of Mechano Growth Factor (MGF), a splice variant of IGF-1 (Insulin-like Growth Factor-1). It plays a key role in muscle repair, growth, and recovery by stimulating satellite cell activation (muscle stem cells).

How PEG-MGF Works

• Muscle Repair & Hypertrophy
  • MGF is produced locally in muscles after mechanical stress (exercise) or damage.
  • It activates satellite cells, promoting muscle fiber repair and growth.
• PEGylation Extends Half-Life
  • Natural MGF breaks down quickly (~5-10 min).
  • PEGylation (attaching polyethylene glycol) extends its half-life to hours or days, making it usable as an injectable drug.Anabolic & Anti-Catabolic EffectsStimulates protein synthesis (muscle building).
  • May protect against muscle wasting (useful in aging or disease).Potential UsesBodybuilding & Athletic Performance (often used in off-label peptide cycles).Medical Research (studied for muscle-wasting conditions like sarcopenia or muscular dystrophy).Injury Recovery (may accelerate healing of muscle tears).
