QUANTITY

How does it compare to similar peptides?


PEG-MGF is a pegylated variant of Mechano Growth Factor (MGF), a splice variant of IGF-1 that plays a role in muscle repair and adaptation.

Unlike regular MGF, PEG-MGF has been chemically modified with a polyethylene glycol (PEG) chain, potentially increasing its stability and half-life in experimental environments.

This makes it a valuable tool for researchers studying muscle recovery, regeneration, and cellular signaling following physical stress or injury models.

When can users expect to see results?

In preclinical research, measurable changes in muscle cell activity, protein synthesis, or regenerative markers have been observed within days to weeks, depending on study design and concentration. Results can vary depending on species and tissue model.

What is PEG-MGF used for?

PEG-MGF is commonly used in:

  • Muscle regeneration and hypertrophy research
  • IGF-1 signaling pathway studies
  • Cellular repair and recovery investigations
  • Tissue regeneration and adaptation models
  • Age-related muscle decline (sarcopenia) research

Quality & Testing

Every batch of PEG-MGF is independently tested by a certified third-party laboratory to verify purity, identity, and composition.

Each analysis is performed using advanced methods such as HPLC and Mass Spectrometry, ensuring the highest research-grade quality.

  • Verified Purity: Each batch is tested for peptide integrity and composition.
  • Third-Party Certified: Analysis is conducted by accredited laboratories with validated testing procedures.
  • Transparent Results: The corresponding Certificate of Analysis (COA) and analytical data can be viewed in the product images above.

All products from My Peptides Lab undergo strict handling, temperature control, and documentation to guarantee consistency and traceability from production to shipment.

Benefits

Research indicates PEG-MGF may potentially:

  • Support studies on muscle repair and regeneration
  • Enhance understanding of IGF-1 receptor signaling
  • Assist research exploring protein synthesis and recovery pathways
  • Contribute to models investigating age-related muscle loss
