PEG-MGF, 5 mg. PEG-MGF is mechano growth factor with polyethylene glycol attached, a construct that does not occur in the body and that clears far more slowly than unmodified MGF.

What is in this vial
It is the smaller of the PEG-MGF vials sold here, which means less substance standing in solution at a time. The powder has no concentration of its own: it is set when you add the water. This vial with 2 ml of bacteriostatic water gives 2.5 mg per millilitre, and with twice that volume, half as much.
The conversion of an amount into insulin syringe units is worked through in the guide on syringe units, and the rules that change once the powder is dissolved are in storage.
Bio-Peptide as the manufacturer
Bio-Peptide has the widest catalogue of the three brands we stock: it is the only one supplying glutathione, NAD+, GHK-Cu, MOTS-C, SLU-PP-332 and semaglutide, so an order from this manufacturer can usually be filled from one supplier. Every vial carries a code under the hologram and a batch certificate, and how to check both is described on the verification page.
What the evidence says
Pegylation is a pharmacokinetic argument, not evidence of an effect. No completed randomised trial of administering either form had been published as of April 2026. The full account, with the sources and the limits, is on the PEG-MGF page, and the background in the guide on MGF and PEG-MGF.
We publish no dosing schedules. Sold as research material, not as a medicine.
Bio-Peptide is one of the two brands here that fill both MGF and its pegylated form, so the comparison between minutes and days of action can be made without changing producer. This vial is the pegylated one, in 5 mg.
Concentration in this vial
| Water added | Concentration | Per unit on a U-100 syringe |
|---|---|---|
| 1 ml | 5 mg/ml | 50 mcg |
| 2 ml | 2.5 mg/ml | 25 mcg |
| 5 ml | 1 mg/ml | 10 mcg |
The table is arithmetic and nothing else: it converts the 5 mg in this vial into the concentration you get for a chosen volume of bacteriostatic water. It is not a dosing recommendation, and we publish none.
This vial next to the other PEG-MGF vials
The same compound is sold here in two other versions: Genheal, 5 mg and Nouveaux Ltd., 10 mg. The molecule is identical in each; what differs is the manufacturer and the amount in the vial. This is the smallest of the 3, so less substance stands in solution at a time.
Also from Bio-Peptide in this group
Within Muscle peptides, Bio-Peptide also supplies ACE-031 10 mg, DES(1-3) IGF-1 1 mg and Follistatin 344 1 mg.
