Overview

A PEGylated form of mechano growth factor designed to resist rapid clearance, extending exposure from minutes to a systemic window measured in hours.

Research profile · for clinicians

Based on research: studied in preclinical muscle work for whether prolonged MGF exposure produces greater satellite-cell recruitment than the native peptide's brief local burst.

Mechanism of action

PEG conjugation shields the peptide from proteolysis and renal clearance, maintaining plasma levels long enough for systemic rather than purely local satellite-cell signalling.

Research record

  • [01]Preclinical work only; no controlled human trials published.
  • [02]Often studied alongside IGF-1 analogues in hypertrophy models.
