Doses studied in research No published studies
What was given to people (or animals) in published studies and official labels, each linked to its source. This is not a recommendation: study products, purity and supervision differ from research-grade vials.
Animal studies: No studies of pegylated MGF were found; the non-pegylated MGF E-domain peptide has only been tested in animals (e.g. a rat heart-attack model using polymer microstructures for local delivery) and cell cultures.
No human or animal studies have tested PEG-MGF itself, so there is no studied dose to report.
What the research says
No published studies of pegylated mechano growth factor (PEG-MGF) as a treatment were found in PubMed — neither human nor animal. It appears only in a review of unregulated performance peptides; evidence for the non-pegylated MGF peptide is limited to animal and cell studies.

Narrative review listing PEG-MGF among unregulated 'research compound' peptides, stratified into the tier lacking human studies, and highlighting endocrine-metabolic and theoretical mitogenic risks.
Study details
- Authors' conclusion
- Peptides are stratified into evidence tiers from regulatory-grade trial data to no human studies; performance benefits are uncertain, and the authors propose a clinical assessment algorithm without legitimising off-label use.
- Limitations
- Narrative review; some peptides lack human studies.
Reported side effects
No human or animal safety data for PEG-MGF exist in the published literature.

PEG-MGF: questions people ask
What is PEG-MGF?
PEGylated mechano growth factor. MGF with a polyethylene-glycol chain attached so it lasts longer in the blood.
How much does PEG-MGF cost?
The cheapest PEG-MGF from an independently tested vendor is $3.30 per mg (Andy Peps Studio, FMP2 PEG MGF 2mg * 10 vials, $66.00). Across 23 listings from 20 vendors the median is $13.40 per mg.
Where can I buy PEG-MGF?
20 vendors tested by Finnrick sell PEG-MGF. The cheapest per mg right now: Andy Peps Studio ($3.30), Baohua Dongnuo Biotechnology BHD ($3.30), LN Peptides ($3.30). 0 of them publish a lab report (COA) for PEG-MGF; compare lab scores and reports in the table above before buying.
How much bacteriostatic water for 2 mg of PEG-MGF?
Adding 2 mL of bacteriostatic water to a 2 mg vial of PEG-MGF gives 1 mg/mL: each 10 units on a U-100 insulin syringe holds 100 mcg. With 1 mL it's 2 mg/mL (200 mcg per 10 units); with 3 mL, 0.667 mg/mL (66.7 mcg per 10 units). More water makes small amounts easier to measure. Mixing charts: 2 mg, 5 mg.
Is PEG-MGF FDA approved?
Not approved. Research use only.
Can PEG-MGF be compounded in the US?
Removed from Category 2 in April 2026; FDA plans to put it to its compounding advisory committee before the end of February 2027. Until FDA adds it to the 503A bulks list, US pharmacies can't compound it from bulk. Compounding status for every peptide.
Does PEG-MGF work? What does the research say?
Evidence grade D (little or no evidence), from 1 papers: No studies of PEG-MGF at all; it appears only in a review of unregulated performance peptides. No published studies of pegylated mechano growth factor (PEG-MGF) as a treatment were found in PubMed — neither human nor animal. It appears only in a review of unregulated performance peptides; evidence for the non-pegylated MGF peptide is limited to animal and cell studies. See the papers.
What dose of PEG-MGF was used in studies?
PEG-MGF is not studied. No studies of pegylated MGF were found; the non-pegylated MGF E-domain peptide has only been tested in animals (e.g. a rat heart-attack model using polymer microstructures for local delivery) and cell cultures. These are amounts used in published studies or official labels, not a recommendation.
