PEG-MGF- Summary
- Cerebrolysin is a porcine brain-derived neuropeptide complex that mimics the action of endogenous neurotrophic factors (BDNF, NGF, GDNF, NT-3). It promotes neurogenesis, neuroprotection, and synaptic plasticity, and is approved in many countries for stroke, traumatic brain injury, and Alzheimer's disease.
- PEG-MGF (Pegylated Mechano Growth Factor) is a modified form of MGF (Mechano Growth Factor) where polyethylene glycol (PEG) chains have been attached to extend its half-life from minutes to days. Native MGF is released locally in muscle in response to mechanical stress and quickly degrades. PEGylation allows systemic administration with sustained circulation, enabling whole-body muscle repair and anabolic signaling rather than the purely local effect of native MGF.
- Half-Life
- Variable for the complex; individual peptide fractions: minutes to hours
- ~3 days (due to PEGylation)
- Admin Route
