TB-500 vs SNAP-8
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 →SNAP-8
SNAP-8 (Acetyl Octapeptide-3) is a cosmetic peptide that reduces the appearance of wrinkles by modulating muscle contraction. It is often called 'topical Botox' though it works through a different mechanism.

| Aspect | TB-500 | SNAP-8 |
|---|---|---|
| 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. | Mimics the N-terminal end of SNAP-25, competing with native SNAP-25 for position in the SNARE complex. This reduces neurotransmitter release at the neuromuscular junction, decreasing muscle contraction. |
| 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: 3-10% concentration in serums or creams, applied 1-2 times daily to target areas (forehead, crow's feet, etc.). |
| Administration | Administered via subcutaneous or intramuscular injection. Some protocols suggest injection near injury sites. | Topical application only. Should be applied to clean skin. Often formulated with penetration enhancers for better absorption. |
| Side Effects | May cause temporary fatigue, headache, or localized irritation at injection sites. | Generally well-tolerated topically. Rare reports of mild skin irritation. No systemic effects at cosmetic doses. |
