PEG MGF (Pegylated Mechano Growth Factor) is a synthetic 24-amino-acid peptide derived from the C-terminal Ec splice variant of insulin-like growth factor 1 (IGF-1Ec), conjugated with polyethylene glycol (PEG) to extend plasma stability in research models. It has been studied in preclinical research models of skeletal muscle satellite cell activation, mechanical-load-induced signaling, and growth factor biology. Heartland Bio Labs supplies PEG MGF as a high-purity lyophilized research compound for qualified laboratory and research use only.

PEG MGF is referenced in published preclinical literature on muscle hypertrophy and tissue repair. In vitro and in vivo studies have investigated its activity in myoblast and satellite cell models, with research interest focused on the IGF-1Ec C-terminal sequence, mechanical-stress signaling pathways, satellite cell quiescence/activation, and downstream growth factor cascades. The PEG conjugation has been studied as a stability-modifying modification relative to native MGF.

Handling Information
PEG MGF should be handled under standard laboratory conditions. Use appropriate personal protective equipment. Avoid repeated freeze-thaw cycles once reconstituted. Handle with care to minimize degradation of the peptide structure. This compound is intended for use by qualified research professionals only.
Storage Requirements
- Long-term (lyophilized): Store at -20°C, protected from light and moisture
- Short-term (reconstituted): Store at 4°C; use within 28 days
- Do not store near solvents, acids, or strong oxidizing agents
- Keep in original vial with cap sealed until point of use
How should I store this peptide?+
Lyophilized peptides should be stored at −20°C in a dry, light-protected environment. Avoid repeated freeze-thaw cycles. Once reconstituted, store at 2-8°C and use within 4-8 weeks depending on the compound.
What should I reconstitute it with?+
Bacteriostatic water or sterile water for research use. We recommend our companion BAC Water for consistency. Specific reconstitution volume depends on your research protocol — refer to the Specifications tab for solubility data.
How quickly do orders ship?+
Orders confirmed before 2:00 PM CT ship the same business day from our facility in Tulsa, OK. Standard US transit is 2-5 business days. Tracking provided at shipment.
Is the COA verified independently?+
Yes. Every product is tested by HPLC for purity (target COA-verified purity) and mass spectrometry for molecular identity before release. The COA is generated from the actual test data, not a generic template.
Can I get bulk or institutional pricing?+
Yes — qualified research facilities and high-volume orders receive tiered pricing. Contact us with your institution information and target quantities.
