What the market shows
PeptidePrices found 15 in-stock listings from 14 vendors, checked through Oct 10, 2026. The lowest 10mg cost is 52% below the vendor median of $179.96; 6 vendors (43%) fall below that median. 14 of 14 vendors (100%) publish public COA evidence.
A public COA link shows that a vendor publishes testing data. It does not prove that every listed vial has a matching current report. Match the product, strength, batch, and lot before relying on a report.
How this report is calculated
The headline and median use each vendor's lowest whole-package checkout cost to obtain at least 10mg. Smaller packages are multiplied until the target is met, while larger packages retain their full checkout price. The lowest package total is shown only as secondary context because package sizes differ. Known public coupon discounts are applied. Shipping, tax, and unverified promotions are excluded.
Research context
What is PEG-MGF? Research, safety, and status
PEG-MGF at a glance
Mechanism
PEGylated analogue of mechano growth factor (MGF, splice variant of IGF-1); activates satellite cells for muscle repair; promotes myoblast proliferation; PEGylation extends half-life dramatically.
Research areas
Muscle repair and hypertrophy; injury recovery; satellite cell activation; post-workout anabolism; anti-catabolic.
Regulatory / research status
Research / preclinical only
Half-life
~24-72 hours (due to PEGylation vs. minutes for native MGF).
Storage
Lyophilized vial: store at -20°C long-term or 2-8°C short-term, protected from light.
Reported side effects
Similar IGF-1 axis risks.

Study highlights
- PEGylation of the MGF E-domain peptide extends its half-life by creating a hydrophilic polymer shield that reduces renal clearance and protease degradation, converting a peptide that degrades in minutes into one with a half-life measured in hours, enabling systemic rather than purely local delivery.
- A sheep model of myocardial infarction found that intravenous administration of the MGF E-domain reduced the area of compromised cardiac muscle by 35% compared to controls and preserved systolic function, suggesting that when delivered systemically at sufficient concentrations the peptide reaches ischemic tissue and is cardioprotective.
- Controlled sustained release of MGF from mesoporous silica scaffolds on titanium prosthetics promoted genuine muscle regeneration into the implant via Akt/mTOR signaling, underscoring the importance of delivery format (slow local release vs. rapid bolus) in translating MGF's bioactivity into functional tissue outcomes.
- Direct head-to-head in vivo data comparing PEG-MGF to native MGF in muscle atrophy models remains limited in the peer-reviewed literature; the PEGylated form's principal advantage is pharmacokinetic, and most mechanistic evidence derives from the unmodified MGF E-domain peptide.
