About PEG-MGF
PEG-MGF is Mechano Growth Factor with a polyethylene glycol chain attached to slow clearance, since native MGF disappears from circulation within minutes. The chemical rationale is sound and pegylation is a well-established pharmaceutical technique. What does not exist is evidence: there are no published human or animal studies on this pegylated form specifically. Everything claimed for it is extrapolated from MGF, which itself has only animal administration data and human expression data. The pegylation also converts a peptide designed for brief local signalling into a systemic one, which is a meaningful change in behaviour rather than simply a longer-lasting version of the same thing.
Key Benefits
- Longer circulating half-life than native MGF
- Fewer injections needed than the unmodified peptide
- Pegylation is a well-established half-life extension method
