FDA: research-only
Last updated · 2026-04-12

PEG-MGF is a PEGylated splice variant of IGF-1 that activates satellite cells in muscle tissue. The PEGylation extends its half-life, enhancing systemic recovery effects post-exercise and making it effective for muscle atrophy reversal and tissue regeneration. Splice variant of IGF-1 that activates satellite cells in muscle tissue. PEGylation extends its half-life for better systemic distribution compared to native MGF. Kickstarts muscle regrowth during and after immobilization. Promotes muscle repair and hypertrophy through satellite cell activation. - Muscle atrophy reversal - Muscle mass recovery post-immobilization - Post-exercise recovery enhancement - Satellite cell activation - Tissue regeneration support - Standard: 200 mcg
