What is PEG-MGF?
Mechano-Growth Factor (MGF) is an anabolic peptide found in muscle, bone, tendon, neural, and cardiac tissue following periods of increased stress. It is a split variant or isoform of insulin-like growth factor-1 (IGF-1), also known as IGF-1Ec. MGF functions to increase stem cell proliferation in given tissues, allowing for more rapid recovery.
What Forms of PEG-MGF Are Available?
PEG-MGF is available as a subcutaneous injections.
What is the Point of Taking MGF & PEG Together?

Since MGF has a relatively short half-life (5-7 minutes), MGF is pegylated. Pegylation is the addition of polyethylene glycol (PEG) to the peptide. The addition of the PEG group is a safe and effective way to increase the MGF half-life to 48-72 hours. Conveniently, the PEG group does not bind itself to other substances in the body and is excreted rapidly via urination.
Who can benefit from using Mechano-Growth Factor?
Primarily, MGF is used in conditions requiring anabolic enhancement, and this includes bony and soft tissue repair (e.g., muscle, tendons, ligaments) following workouts or injury, sarcopenia (muscle wasting), stroke, or heart attack. MGF is especially beneficial for individuals requiring enhanced muscle building and recovery following workouts as performed by bodybuilders and other athletes.

What You Need to Know
PEG-MGF is a safe and effective option for use in patients who are looking to improve recovery and repair through anabolic signaling. PEG-MGF should be used with caution in patients who are prone to hypoglycemia. Furthermore, patient-specific dosing and injection schedules are vital to avoid unwanted tissue hypertrophy.
PEG-MGF Dosing
Dosing protocols can be effected by several factors. Included in this are your weight, experience with peptides, what other anabolic’s you may be using, and of course personal goals. Typical dosing ranges anywhere from 100 mcg – 500 mcg. We feel that 200 mcg is an effective dose for most people.
