TB-500 vs Argireline
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
TB-500
Thymosin Beta-4 (TB-500) is a naturally occurring peptide present in almost all human and animal cells. It plays a crucial role in tissue repair and regeneration.
Full details →Argireline
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 | TB-500 | Argireline |
|---|---|---|
| Mechanism | TB-500 promotes cell migration and differentiation, regulates actin (a cell-building protein), and reduces inflammation. It supports the formation of new blood vessels and wound healing. | 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 2-2.5mg twice weekly during the loading phase, followed by maintenance dosing of 2mg every 2 weeks. | Topical: 5-10% concentration in serums, applied twice daily. Higher concentrations used in professional treatments. |
| Administration | Administered via subcutaneous or intramuscular injection. Some protocols suggest injection near injury sites. | Topical application to clean skin. Most effective on expression lines (forehead, crow's feet). Consistent use required for visible results. |
| Side Effects | May cause temporary fatigue, headache, or localized irritation at injection sites. | Generally very well-tolerated. Occasional mild irritation or dryness. No systemic absorption at cosmetic doses. |
