Product overview
Generic Peptides PEG MGF - 2 mg and 5 mg Vials
Generic Peptides PEG MGF is mechano growth factor with a polyethylene glycol chain attached, sold as a lyophilized research powder in 2 mg and 5 mg vials. MGF is the IGF-IEc splice variant of the IGF-1 gene and its active part is a 24 amino acid C-terminal peptide with the sequence YQPPSTNKNTKSQRRKGSTFEERK. Read as a local signal, it is placed beside the systemic analog IGF-1 LR3.
- Two vial sizes - 2 mg and 5 mg
- Pegylated MGF - IGF-IEc splice variant
- Lyophilized powder - needs a solvent
- GMP-made, HPLC-verified, COA on file
Variant Comparison
Both vials hold the same peptide, so the choice is how much material one series needs.
| Variant | Dosage | Form and quantity | Best use |
|---|---|---|---|
| PEG MGF 2 mg | 2 mg | Lyophilized vial | Short runs |
| PEG MGF 5 mg | 5 mg | Lyophilized vial | Extended series |
The 5 mg vial carries two and a half times the material of the 2 mg vial and is the size with a U.S. domestic option. A repair peptide such as TB 500 or BPC-157 is the usual companion when a tissue arm is read next to a muscle cell arm.
How PEG MGF Works
In muscle, the peptide is described as acting on local satellite cells: it supports myogenic differentiation, protein synthesis and anti-apoptotic signalling in models, and its expression is induced within an hour of mechanical load and can stay raised for up to eight weeks. Attaching polyethylene glycol to the tyrosine slows degradation, although published half-life figures disagree widely, and synthetic versions carry unnatural D-amino acids in the QRRK domain to resist enzymes. No human pharmacokinetic work exists. One paper has raised a potential carcinogenicity question that has not been confirmed independently.
Reconstitution & Storage
The powder is dissolved with sterile or bacteriostatic water, which is not in the pack, added down the vial wall and swirled rather than shaken. Divide the amount on the label by the millilitres added to read the concentration. Keep the lyophilized vial at 2-8 C or -20 C, protected from light, and the mixed solution at 2-8 C for about four weeks.
Dosage & Administration
No human dose is stated here and the vial is not a medicine. PEG MGF has no approved indication and no human pharmacokinetic profile, so nothing on this page is a dosing guide. Mechano growth factors are named in WADA class S2.3 and are banned in sport at all times. A releasing factor such as Somatropin belongs to a different part of the axis and is not a substitute.
Supplied for laboratory research only, not for human or veterinary use. Information provided is for educational purposes only and does not constitute medical advice. Consult a qualified healthcare professional before use. PEG MGF is supplied as a lyophilized powder and stays stable when the vial is kept cold and dry.

FAQ
Before you ask
Questions, answered
PEG MGF is mechano growth factor with a polyethylene glycol chain added. MGF is the IGF-IEc splice variant of the IGF-1 gene, and the active part used in research is a 24 amino acid C-terminal peptide, YQPPSTNKNTKSQRRKGSTFEERK, with a formula of C121H199N41O40 and a mass of about 2868 g/mol. Pegylation is what separates it from plain MGF.
Unmodified MGF is cleared within minutes in the literature, so a polyethylene glycol chain is attached to the tyrosine to slow enzymatic breakdown and keep the peptide in circulation longer. Reported half-life figures for the pegylated form range from about 30 to 60 minutes in vendor guides to 48 to 72 hours in clinical write-ups, and no human pharmacokinetic study has settled the question.
Sterile or bacteriostatic water is added down the wall of the vial and the contents are swirled, not shaken, until the powder has dissolved; the solvent is not included in the pack. Concentration is the amount on the label divided by the millilitres added. A 2 mg vial plus 1 mL gives 2 mg per mL, and a 2 mg vial plus 2 mL gives 1 mg per mL.
The lyophilized vial is kept at 2-8 C or -20 C, protected from light and moisture, and the mixed solution at 2-8 C for about four weeks. Repeated freeze and thaw cycles are avoided, as is vigorous shaking, which can damage the peptide. A solution that is cloudy or contains particles is discarded rather than used in an experiment.
No human safety data exist for PEG MGF, so side effects in humans are not characterised. In the peptide class, injection site reactions are the common local effect. One scientific paper has raised a question about potential carcinogenicity for MGF, and that question has not been confirmed by independent work. Long term effects of the pegylated form are unknown, and no human dosing has been validated.
Yes. Mechano growth factors are named in class S2.3, growth factors and growth factor modulators, of the WADA Prohibited List, and everything in that class is prohibited at all times, in and out of competition. The listing covers the class rather than one brand, so a pegylated version falls inside it in the same way as plain MGF.
Yes, both vial sizes are in stock on this page and can be ordered directly. The 2 mg and 5 mg vials ship internationally, and the 5 mg vial also has a U.S. domestic option. International shipping is about USD 35, orders are processed in one to two business days and transit runs four to ten days depending on the destination country.
