Mechanism & published research
IGF-1 receptor agonism with reduced binding-protein affinity, extending activity in research models.
Growth and anabolic signaling characterized in cell and animal models.
Honest note on evidence: Evidence is preclinical; handle as a potent growth factor per research protocol.
Descriptions summarize existing published research and are not claims about outcomes from use. Every citation states its study type and population.
How it compares
| Versus | Attribute | Note |
|---|---|---|
| PEG-MGF | Pathway | Both touch IGF/MGF biology from different angles. |
Reconstitution
Concentration math only: add bacteriostatic water to the vial and the resulting concentration is shown below. This is not usage guidance.
| Vial | Bacteriostatic water | Concentration |
|---|---|---|
| 1 mg | 1 mL | 1 mg/mL |
Storage & stability
| State | Temperature | Duration |
|---|---|---|
| Lyophilized (unopened) | -20°C | 24 months |
| Reconstituted | 2–8°C | up to 2 weeks |
Reviews
Reviews are collected post-delivery and screened to exclude any human-use or dosing-outcome claims before publication. They speak to product quality, shipping, and COA accuracy.
“Purity matched the label and the identity page was attached. Reconstituted clear.”
