Overview
About PEG-MGF.
PEG-MGF is a synthetic peptide reproducing the 24-residue mechano growth factor (MGF / IGF-1Ec) C-terminal E-domain, N-terminally conjugated to polyethylene glycol to slow enzymatic degradation and extend circulating half-life versus native MGF. As an IGF-1 splice variant, it is studied in research models for skeletal-muscle repair and satellite-cell activation signaling.

FAQ
PEG-MGF — frequently asked by B2B buyers.
What is PEG-MGF and what form does Pepti supply?
PEG-MGF is a pegylated version of mechano growth factor (MGF), the alternatively spliced C-terminal E-domain of IGF-1. Pepti supplies it as a lyophilized (freeze-dried) powder in 2 mg vials for laboratory research and private-label programs.
What analytical documentation ships with each lot?
Every production lot includes a batch-linked COA reporting HPLC purity and mass-spectrometry (MS) identity confirmation. Additional documentation such as batch photos, appearance, and residual-solvent or endotoxin (only if specifically ordered and tested) data can be provided on request for qualifying B2B orders.
What is the molecular weight of PEG-MGF?
The MGF peptide core has a mass of approximately 2867 g/mol, but PEG-MGF is a PEG conjugate, so its total mass depends on the polyethylene glycol chain used and is not a single fixed value. The exact conjugate specification is confirmed per lot on the COA and on RFQ rather than quoted as one universal number.
What are the MOQ, vial size, and private-label options?
Standard supply is 2 mg vials at a minimum order of 50 kits (500 vials). OEM and private-label services, including custom labeling, vial fill, and bulk peptide sourcing, are available; contact us with your target volume for a quotation.
Is PEG-MGF sold for therapeutic use?
No. PEG-MGF is offered strictly as a research-use-only material and is not for consumer or veterinary consumption, diagnostic, or therapeutic use. Buyers are responsible for compliance with applicable regulations in their jurisdiction; note that MGF-class peptides are prohibited in competitive sport under WADA.
