Leuphasyl vs Thymosin Alpha-1
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Leuphasyl
Leuphasyl (Pentapeptide-18) is a cosmetic peptide that reduces muscle tension through a mechanism similar to enkephalins. Often combined with Syn-Ake for enhanced anti-wrinkle effects.

Thymosin Alpha-1 is a peptide naturally produced by the thymus gland that plays a crucial role in immune system modulation. It is approved in over 35 countries for various conditions including hepatitis B and C.
Full details →Side-by-Side Comparison
| Aspect | Leuphasyl | Thymosin Alpha-1 |
|---|---|---|
| Mechanism | Mimics enkephalin and binds to enkephalin receptors on muscle cells, reducing acetylcholine release and thereby decreasing muscle contraction intensity. | Enhances T-cell function and maturation, stimulates dendritic cell activity, and modulates cytokine production. Promotes the differentiation of stem cells into mature T lymphocytes. |
| Typical Dosage | Topical: 3-8% concentration in serums. Often used in combination products with other muscle-relaxing peptides. | Clinical dosing typically ranges from 1.6mg to 6.4mg administered subcutaneously 2-3 times weekly. Research protocols may vary. |
| Administration | Topical application to expression lines. Best results with consistent twice-daily use over 8+ weeks. | Subcutaneous injection. Often used in cycles or as part of comprehensive immune support protocols. |
| Side Effects | Very well-tolerated topically. No significant adverse effects reported at cosmetic concentrations. | Generally well-tolerated. Rare side effects include injection site reactions, mild flu-like symptoms, and temporary fatigue. |
