How PEG-MGF works
A pegylated form of mechano growth factor, an IGF-1 splice variant expressed by muscle in response to mechanical loading and damage. Pegylation is intended to slow clearance of an otherwise very short-lived peptide.
PEG-MGF dosing — what the literature actually supports
Animal data only. MGF and its pegylated form have been studied in rodent muscle-damage models and in cell culture. There is no human trial, no pharmacokinetic data in humans for the pegylated form, and therefore nothing to cite as a schedule.
We publish a schedule when there is a citable human source and we say so when there is not. Filling this space with a number nobody measured would make the page look more complete and be worth less than nothing to you.
Reconstitution and measurement
This part is arithmetic and does not depend on the evidence level. Concentration is vial size divided by the bacteriostatic water you add. Draw volume is your target amount divided by that concentration. Units are draw volume times 100, because a U-100 syringe reads 100 units per millilitre.

Storage and stability
Dry powder
Cold, dark and dry. Lyophilized peptide is the stable form — keep it that way until you intend to use it.
After reconstitution
Refrigerate at 2–8 °C, protect from light, and plan around a limited window. Do not freeze a reconstituted vial — freeze-thaw damages peptides.
Mixing
Run bacteriostatic water down the inside wall of the vial rather than onto the powder, then swirl. Never shake.
Inspect before use
A clear solution is expected. Cloudiness or particles mean discard, not use.

Reported effects
- No human safety data.
- Rodent work reports effects on satellite-cell activation after muscle damage.
Sourcing PEG-MGF
Our featured supplier does not stock this compound, and we are not going to point you at a vendor we have not looked at. Use the COA checklist on whoever you do buy from, and check the batch number on the certificate against the vial you receive.
