Overview
Compounds in this area appear in the tissue-repair and recovery literature, often studied for angiogenesis, cytoprotection, and cell-migration signaling. The evidence base is predominantly preclinical, so this guide labels the study type for every cited claim and never reads animal or in-vitro data as human efficacy.
A PEGylated form of mechano-growth factor (an IGF-1 splice variant), studied for muscle-repair signaling with improved stability.
Evidence at a glance: Preclinical (animal) evidence
The cited evidence here is preclinical animal-model work, with limited or no human-trial data. Read the research profile accordingly.

Researched mechanism
MGF signaling studied for satellite-cell activation; PEGylation extends solution stability.
Described as a mechanism characterized in the literature, not an effect you should expect from use.
What the published research shows
Satellite-cell activation reported in muscle-injury models.
Honest note on evidence: Evidence is preclinical and limited; the PEGylated form specifically has minimal published data.
Every citation states its study type and population, so preclinical data is never presented as human-efficacy evidence.
How it compares
| Versus | Attribute | Note |
|---|---|---|
| IGF-1 LR3 | Class | Related IGF biology; MGF is a splice variant. |
Reconstitution
Concentration math only: adding bacteriostatic water to the vial gives the resulting mg/mL shown below. This is not usage guidance.
| Vial | Bacteriostatic water | Concentration |
|---|---|---|
| 2 mg | 2 mL | 1 mg/mL |
| 5 mg | 5 mL | 1 mg/mL |
Storage & stability
| State | Temperature | Duration |
|---|---|---|
| Lyophilized (unopened) | -20°C | 24 months |
| Reconstituted | 2–8°C | up to 3 weeks |
Common questions
What does PEGylation do?+
It attaches polyethylene glycol to extend stability/half-life in research use.
