PEG-MGF vs Argireline
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
PEG-MGF
PEG-MGF (PEGylated Mechano Growth Factor) is a variant of IGF-1 that is produced in response to muscle damage. PEGylation extends its half-life from minutes to several hours, making it practical for use.

Argireline (Acetyl Hexapeptide-3) is a widely-used cosmetic peptide that reduces wrinkle depth by inhibiting neurotransmitter release. One of the first 'Botox-like' peptides developed for topical use.

| Aspect | PEG-MGF | Argireline |
|---|---|---|
| Mechanism | Activates muscle satellite cells (stem cells) and promotes their fusion to existing muscle fibers for repair and growth. MGF is produced naturally in response to mechanical stress on muscles. | Inhibits the formation of the SNARE complex required for neurotransmitter release, reducing the intensity of muscle contractions that cause expression lines. |
| Typical Dosage | Research protocols typically use 200-400mcg injected into targeted muscle groups 2-3 times weekly, usually post-workout. | Topical: 5-10% concentration in serums, applied twice daily. Higher concentrations used in professional treatments. |
| Administration | Intramuscular injection, ideally into muscles trained that day. Best administered post-workout when satellite cell activation is relevant. | Topical application to clean skin. Most effective on expression lines (forehead, crow's feet). Consistent use required for visible results. |
| Side Effects | Injection site soreness, potential hypoglycemia, and localized swelling. Generally well-tolerated. | Generally very well-tolerated. Occasional mild irritation or dryness. No systemic absorption at cosmetic doses. |
