How Thymalin/Thymulin Works

Thymalin (thymulin) is a nonapeptide produced by thymic epithelial cells that requires zinc binding for biological activity. The zinc-thymulin complex induces T-cell differentiation markers, modulates the release of thymic hormones, stimulates T-helper and T-suppressor cell activity, and enhances NK cell cytotoxicity. It acts through modulation of multiple cytokines and interleukins including IL-1, IL-6, and TNF-alpha, playing a critical role in immune system homeostasis and thymic function.

Research Applications

1
Immune system restoration in aging
2
Thymic involution reversal
3
Zinc-dependent immune modulation
4
Anti-aging and longevity (bioregulator therapy)

Reconstitution Calculator

Add this much bacteriostatic water:
10.0 mL
10 mg Thymalin/Thymulin + 10.0 mL BAC water = 1 mg/mL

Inject bacteriostatic water slowly along the vial wall. Gently swirl until dissolved — never shake. Store reconstituted solution at 2-8°C and use within 30 days.

Frequently Asked Questions

Thymalin/Thymulin (CAS: 63958-90-7) is a research compound, with a molecular weight of 858.86 Da in the Healing / Recovery category. Thymalin (thymulin) is a nonapeptide produced by thymic epithelial cells that requires zinc binding for biological activity. The zinc-thymulin complex induces T-cell differentiation markers, modulates the release of thymic hormones, stimulates T-helper and T-suppressor cell activity, and enhances NK cell cytotoxicity. Researchers commonly investigate Thymalin/Thymulin for Immune system restoration in aging, Thymic involution reversal, Zinc-dependent immune modulation. Every vial from MiPeptidos includes batch-specific analytical documentation.
To reconstitute your Thymalin/Thymulin 10mg vial, let it reach room temperature for about 15-20 minutes out of the freezer. Slowly inject 2-3mL of bacteriostatic water along the inside wall of the vial — never aim directly at the peptide cake. Gently swirl until the powder fully dissolves; never shake, as this can denature the peptide. Store reconstituted Thymalin/Thymulin at 2-8°C and use within 30 days. MiPeptidos includes bacteriostatic water for purchase alongside all peptides.
Thymalin (Thymulin) is a much smaller thymic peptide (9 amino acids, 859 Da, requires zinc for activity) compared to Thymosin Alpha-1 (28 amino acids, 3108 Da). Thymulin specifically requires a Zn2+ ion for biological activity, binding to T-cell receptors to promote maturation and differentiation. It was originally isolated by Bach and Dardenne and is one of the Khavinson bioregulatory peptides studied for immune aging. MiPeptidos offers both thymic peptides.
Store lyophilized Thymalin/Thymulin at -20°C for maximum long-term stability — properly stored, it remains potent for 24+ months. Once reconstituted with bacteriostatic water, keep it refrigerated at 2-8°C and use within 30 days. In research applications, Thymalin/Thymulin has a reported half-life of Short; minutes to hours in circulation, which informs dosing frequency and protocol design. Avoid repeated freeze-thaw cycles and protect from direct light. MiPeptidos ships every order with cold-chain packaging to maintain integrity during transit.
Every Thymalin/Thymulin order from MiPeptidos includes a batch-specific Certificate of Analysis. Our current batch (HR-THYM-2600315, tested March 20, 2026) shows 99.8% purity by HPLC, mass spectrometry confirmation at 858.86 Da, endotoxin levels below 0.1 EU/mg, and passing sterility per USP <71>. This level of documentation ensures you can verify compound identity and purity before beginning your research. MiPeptidos also offers bulk pricing on orders of 50+ vials — contact info@mipeptidos.com.
