What is PEG-MGF?
PEG-MGF is the E-peptide of mechano growth factor with a chain of polyethylene glycol attached to it. Polyethylene glycol, usually shortened to PEG, is a water-soluble polymer used to change how a peptide behaves in solution and in the body. Standard PEG is made as chains of varying length, which would give the finished material a range of molecular weights rather than one fixed number. Single-length PEG also exists, and the supplier has not said which kind this product carries. No published study has tested this PEGylated compound, so the points below describe what attaching PEG does in general.

PEG-MGF Research & Reference
What PEG-MGF does in published studies, and how to work with it in the laboratory, are covered in full on two dedicated pages rather than summarised here, so neither the evidence nor the handling detail is cut short.

Frequently Asked Questions
Is PEG-MGF third-party tested for purity?+−
Yes. Every batch of PEG-MGF is tested by an independent third-party laboratory using HPLC and MS-UPLC, confirming purity and mass identity before the batch is released. Pure Peptides does not test its own material.
Can I see the Certificate of Analysis before buying?+−
Yes. The Certificate of Analysis for the batch currently in stock can be viewed and downloaded directly on this page, before you place an order. Each certificate states the batch number, the measured purity, and the date of analysis, and can be verified independently with the issuing laboratory using the report number it carries.
What does "Research Use Only" mean?+−
It means PEG-MGF is supplied for in-vitro laboratory research and for no other purpose, and must not be administered to humans or animals. PEG-MGF is legal to purchase in the United States for in vitro and non-clinical laboratory research. It has no FDA approval and no approved human use. PEG-MGF falls under section S2 of the WADA Prohibited List for competitive athletes, a separate consideration from its legal research status. Sold strictly for qualified research use, not human or veterinary administration.
How is PEG-MGF shipped and stored?+−
PEG-MGF ships from US stock with cold-chain packaging and full tracking; orders placed before noon EST on business days are typically dispatched the same business day. On arrival, store the lyophilized powder at -20°C or below, dry and protected from light.
What research has been published on PEG-MGF?+−
None on the compound itself. One 2026 review names it among peptides sold as research compounds and reports no measurement on it. The PEG-MGF research article lists the searches run and what each returned. Mechano growth factor is a separate product with its own literature, and that literature is not repeated here, because a PEG chain changes mass, solubility and clearance.
Is PEG-MGF the same as MGF?+−
No. PEG-MGF is the mechano growth factor E-peptide with a polyethylene glycol chain attached. The chain increases the molecular weight and changes the molecule's physical properties. Published work on mechano growth factor was done on the unmodified peptide and does not describe this material.
