Thymalin vs SNAP-8
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Thymalin
Thymalin is a polypeptide preparation derived from calf thymus. Developed in Russia, it has been used for decades to support immune function and has shown potential anti-aging effects in long-term studies.

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 | Thymalin | SNAP-8 |
|---|---|---|
| Mechanism | Regulates the ratio of T-cell subpopulations, stimulates cellular immunity, and enhances phagocytosis. Also affects neuroendocrine regulation and may influence melatonin production. | 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 | Clinical protocols: 5-20mg daily intramuscularly for 3-10 days. Often cycled 1-2 times per year for maintenance. | Topical: 3-10% concentration in serums or creams, applied 1-2 times daily to target areas (forehead, crow's feet, etc.). |
| Administration | Intramuscular injection. Usually administered in short courses rather than continuously. Often combined with Epithalamin for anti-aging protocols. | Topical application only. Should be applied to clean skin. Often formulated with penetration enhancers for better absorption. |
| Side Effects | Generally well-tolerated. May cause injection site reactions or temporary flu-like symptoms as immune function is modulated. | Generally well-tolerated topically. Rare reports of mild skin irritation. No systemic effects at cosmetic doses. |
