Palmitoyl Tripeptide-1 vs Thymalin
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Palmitoyl Tripeptide-1
Palmitoyl Tripeptide-1 (Pal-GHK) is a lipopeptide that stimulates collagen production. It's one of two peptides in the Matrixyl 3000 complex, working synergistically with Palmitoyl Tetrapeptide-7.
Full details →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.
Full details →Side-by-Side Comparison
| Aspect | Palmitoyl Tripeptide-1 | Thymalin |
|---|---|---|
| Dose Range | 500 mcg–2 mg | 5 mg–10 mg |
| Frequency | 2x daily | 1x daily |
| Cycle Length | 4–12 weeks | 1–2 weeks |
| Route | topical | intramuscular |
| Mechanism | Mimics the skin's own mechanism for producing collagen by acting as a messenger peptide that signals fibroblasts to produce more collagen and other extracellular matrix components. | Regulates the ratio of T-cell subpopulations, stimulates cellular immunity, and enhances phagocytosis. Also affects neuroendocrine regulation and may influence melatonin production. |
| Typical Dosage | Topical: Typically 2-4% in serums, often combined with Palmitoyl Tetrapeptide-7 as Matrixyl 3000. | Clinical protocols: 5-20mg daily intramuscularly for 3-10 days. Often cycled 1-2 times per year for maintenance. |
| Administration | Topical application 1-2 times daily. The palmitoyl group enhances skin penetration compared to non-lipidated versions. | Intramuscular injection. Usually administered in short courses rather than continuously. Often combined with Epithalamin for anti-aging protocols. |
| Side Effects | Very well-tolerated. Suitable for most skin types including sensitive skin. | Generally well-tolerated. May cause injection site reactions or temporary flu-like symptoms as immune function is modulated. |
