Thymulin vs KPV
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Thymulin
Thymulin (Facteur Thymique Sérique) is a zinc-dependent nonapeptide hormone produced by thymic epithelial cells. It plays important roles in T-cell differentiation and immune system maturation.
Full details →KPV
KPV is a tripeptide (Lys-Pro-Val) derived from alpha-melanocyte-stimulating hormone (α-MSH). It retains the potent anti-inflammatory properties of the parent hormone without the tanning or other melanocortin effects.

| Aspect | Thymulin | KPV |
|---|---|---|
| Mechanism | Requires zinc for biological activity. Promotes T-cell differentiation, modulates cytokine production, and influences neuroendocrine function. Levels decline significantly with age. | Inhibits NF-κB activation and reduces inflammatory cytokine production. Enters cells and directly modulates inflammatory signaling without requiring melanocortin receptors. |
| Typical Dosage | Research protocols vary. Often studied alongside zinc supplementation. Typical research doses in the microgram range. | Oral/sublingual: 200-500mcg 1-3 times daily. Topical formulations for localized inflammation. Also used in enemas for gut inflammation. |
| Administration | Subcutaneous or intramuscular injection in research settings. Requires adequate zinc status for activity. | Can be taken orally, sublingually, or as suppositories/enemas for gut inflammation. Topical use for skin conditions. Stable orally unlike most peptides. |
| Side Effects | Limited data on exogenous administration. Theoretical effects on immune function require monitoring. | Generally very well-tolerated. Minimal systemic effects due to targeted anti-inflammatory action. |
