How long will one vial last?
Based on standard research protocols, here's exactly what to expect from a single 2mg vial — and when to plan your next order.
Actual duration may vary based on your specific protocol. Always consult your research guidelines for precise dosing schedules.
Scientific Background
Mechanism of Action
MGF is produced locally in muscle tissue in response to mechanical loading. It activates quiescent satellite cells (muscle stem cells) to proliferate and fuse with damaged fibers. PEGylation attaches polyethylene glycol chains to the peptide, extending half-life from minutes to days.
Clinical Context
PEG-MGF represents a targeted approach to muscle repair — acting locally at sites of mechanical stress rather than systemically. This makes it particularly relevant for injury recovery research.
Research Highlights
- PEGylation extends MGF half-life from ~5 minutes to several days
- Shown to increase muscle fiber cross-sectional area by 25% in rodent models
- Activates satellite cells independently of the systemic IGF-1 axis
- Research suggests synergistic effects when combined with IGF-1 LR3
