What PEG-MGF is
PEG-MGF is a pegylated form of mechano growth factor, the IGF-1 splice variant expressed by muscle tissue after mechanical loading or damage. Pegylation is intended to extend the very short half-life of native MGF, and the published work focuses on satellite cell activation in rodent muscle injury models.
Because the pegylation step is part of the manufacturing rather than the sequence, two vials with the same product name can behave very differently. Certificates that describe only the peptide sequence tell you nothing about whether the pegylation was performed properly.
What the evidence base looks like
The published record is early: a coherent mechanism, a handful of encouraging studies, and very little independent replication at human scale.
Our library records roughly 19 relevant publications for PEG-MGF and grades the evidence as emerging. That grade describes the weight of research, not a judgement about safety or effect, and it is reviewed as new work is published.
Supplier quality: what to check on PEG-MGF
Suppliers rarely publish data on the pegylation itself, so ask what analysis covers the conjugate rather than the base peptide.
The practical checklist is the same on every product but weighted differently here: a batch-matched certificate of analysis, an identity method appropriate to this molecule rather than purity alone, clear peptide content per 2mg vial, and a supplier that will answer a technical question before taking payment.
Typical UK pricing
The lowest price we currently track for a 2mg vial is £24.95, against a market median nearer £35. Compare on price per milligram rather than per vial, because vial sizes across suppliers are rarely identical.
A listing well below the tracked low is worth investigating rather than celebrating. On this compound the cost of doing it properly is largely analytical, and that is the first thing an unusually cheap supplier stops paying for.
Frequently asked
Is PEG-MGF approved for human use?
No. Everything listed here is supplied for laboratory research use only, and nothing on this page is medical advice.
How much should PEG-MGF cost?
Tracked UK prices start around £24.95 for a 2mg vial, with the market median closer to £35.
What is the single most useful check on PEG-MGF?
Suppliers rarely publish data on the pegylation itself, so ask what analysis covers the conjugate rather than the base peptide.
