PEG-MGF (Pegylated Mechano Growth Factor) is offered in a convenient 5mg / 2ml pre-filled research pen – the pegylated isoform of MGF (Mechano Growth Factor), specifically engineered for laboratory studies of localized muscle repair, satellite cell activation, and site-specific anabolic/hyperplastic responses.

PEG-MGF is the biologically active C-terminal peptide of IGF-1 Ec (Mechano Growth Factor), covalently attached to a polyethylene glycol (PEG) chain. This modification dramatically extends the compound’s half-life from minutes (native MGF) to several days in biological systems, allowing sustained local action without rapid clearance, making it ideal for investigating tissue-specific regenerative and hypertrophic pathways.

Primary research focus areas include:

• Potent stimulation of satellite cell proliferation, differentiation, and fusion into existing muscle fibers (true hyperplasia)
• Localized muscle repair and regeneration following mechanical damage, injury, or overload stress
• Enhanced protein synthesis and anabolic signaling in targeted muscle groups
• Investigation of site-specific vs. systemic growth effects (administered locally in many models)
• Accelerated recovery of muscle tissue architecture and function post-trauma or intense exercise protocols
• Synergistic potential with other growth factors (e.g., IGF-1 LR3) for combined regenerative and hypertrophic studies
• Exploration of PEG-MGF’s role in tendon/ligament healing, cardiac muscle repair, and neuroprotection models

The 5mg strength in a 2ml pen provides optimal volume for precise, localized micro-dosing protocols or experiments requiring moderate cumulative exposure, with the pegylation ensuring prolonged tissue retention and activity at the site of administration.

Product highlights:

• Ultra-high purity PEG-MGF (>98.5% – third-party HPLC & MS verified)
• Sterile, ready-to-use pre-filled pen injector – accurate delivery and exceptional lab convenience
• Extended half-life through PEGylation – sustained local action for days
