Known For

PEGylated version of MGF. The PEG attachment extends the half-life from minutes to hours. Better bioavailability and more practical dosing than standard MGF. Promotes muscle satellite cell activation.

Mechanism of Action

PEGylated version of MGF — PEG chain extends half-life from minutes to hours/days. Allows systemic distribution and satellite cell activation.

Body vs. External Supply

🔴 Exogenous (replaces natural)

Brand / Trade Names

No pharmaceutical brand Research peptide only

Typical Research Dosage

200mcg IM 2-3x per week. Inject into target muscle groups. Some use SubQ systemically.

Vial Duration Guide

2mg vial at 200mcg 3x/wk = ~3.3 weeks.

Recommended Vial Size

★ 2mg (only size) At 200mcg 3x/wk = ~3.3 weeks ✓. Fits within shelf life.

Time to Effects

EARLY: 2-4 weeks FULL: 6-8 weeks More reliable than standard MGF due to extended half-life. Week 2-4: Improved muscle recovery in target areas. Week 6-8: Enhanced repair and growth in trained muscles. Minimum commitment: 6 weeks. Works best as part of a broader GH/recovery stack.

Contraindications & Do Not Combine

• Do NOT inject on same day as IGF-1 LR3 (alternate days) • Do NOT combine with standard MGF (pick one version)

Common Side Effects

Injection site reactions, flu-like symptoms (reported), limited safety data

Drug Interactions

Unknown — very limited research

Reversibility

Reversible

Key Peer-Reviewed References

All studies are published in indexed journals unless otherwise noted.

• Same research base as MGF with PEGylation for extended half-life • Very limited published research • NOT FDA APPROVED • No human clinical trials

Research Disclaimer

Almost all data is preclinical (animal or in-vitro). No large-scale randomised controlled human trials are available for most compounds on this catalogue. This information is provided for research reference only.

Storage Requirements

Reconstituted: 2-8°C, 14-21 days

State	Condition	Duration
Lyophilised (sealed)	2–8°C	12-24 months
Reconstituted	2-8C	3–4 weeks

Reconstitution Note

Reconstitute with bacteriostatic water (BAC water). Do not shake vigorously -- swirl gently to dissolve. Inject BAC water slowly down the side of the vial to avoid denaturing the peptide.
