PEG-MGF is a polyethylene-glycol conjugate of the 24-residue C-terminal E-domain peptide of IGF-1Ec, the mechanical-load-induced splice variant of IGF-1. No study of the pegylated construct has been published in any species: the single PubMed-indexed source that mentions it is a 2026 review confirming the absence of human clinical data and noting that the effects observed with native IGF-1Ec or unmodified E-domain peptides cannot be assumed to apply to a PEG conjugate. This index grades unmodified MGF at D on the strength of its cell and rodent work; PEG-MGF has no separate evidence base at all.
// our evidence grade — unedited
An exact-phrase PubMed search for 'PEG-MGF' returns exactly one indexed publication — a 2026 endocrinology review which states there are 'no peer-reviewed clinical studies in humans' — and zero records exist for 'pegylated mechano growth factor'; ClinicalTrials.gov returns zero registered studies. Every mechanistic claim made for the product belongs to unmodified MGF or to endogenous IGF-1Ec, and the pegylation is precisely the change that blocks transfer of that evidence.
We grade this compound and we sell it. The grade is set against our published criteria before any stocking decision and is not adjusted because it is in the catalogue.

| full name | PEGylated mechano growth factor — a polyethylene-glycol conjugate of the IGF-1Ec C-terminal E-domain peptide |
| purity | ≥ 98% HPLC |
| form | lyophilised powder, sealed vial |
| storage | Lyophilised powder is stored desiccated at -20 °C and protected from light. Once reconstituted, laboratory practice is refrigeration at 2-8 °C for short-term use, or aliquoting and freezing to avoid repeated freeze-thaw cycles. Handling information only; this material has no approved human use. |
| solubility | Short hydrophilic peptide, readily soluble in sterile or bacteriostatic water and in dilute aqueous buffer. Lot-specific solubility is stated on the certificate of analysis. |
