Peptide
PEG-MGF
SavePEGylated Mechano Growth Factor, a modified IGF-1 splice variant with polyethylene glycol conjugation to extend its otherwise ultra-short half-life.
Quick verdict
PEGylation addresses native MGF's minutes-long half-life. No human clinical data. Used primarily in bodybuilding circles with unverified products.
Evidence score
A rough internal score reflecting quantity, quality, and consistency of human evidence. Not a clinical recommendation.
What the research shows
Rationale is to extend MGF half-life for practical dosing. No published human pharmacokinetic or efficacy studies. Animal data are sparse.
Benefits
- Extended half-life over native MGF
- Theoretical satellite cell activation for muscle repair
Dosage notes
No validated dosing. Bodybuilding forums cite 200 mcg intramuscularly 2–3 times weekly.
Side effects
- Unknown in humans
- PEG-related immune reactions possible
- Injection-site reactions
Who should be cautious
No clinical data. Gray-market PEG-MGF products may not contain the claimed compound. PEGylation adds immunogenicity risk.
What this page cannot tell you
Entirely speculative therapeutic utility. PEGylation may alter bioactivity in unpredictable ways.
