Thymic Peptide Complex for Immune and Longevity Research
Thymalin (10mg) will be supplied in Australia by Aussie Peptides with fast domestic shipping to all states and territories.
Thymalin is a peptide preparation derived from thymic tissue, first characterised in the Soviet research program that also produced Epitalon. Research interest centres on its regulatory effect on the immune system: restoring the balance of T-cell subsets, supporting thymic function in ageing models, and modulating inflammatory signalling. Its shortest active fragment, the dipeptide Thymogen, is studied alongside it.
It sits naturally next to Thymosin Alpha-1 in the range. Both are thymic in origin, but Thymosin Alpha-1 is a single defined 28-amino-acid peptide with a deep clinical literature, while Thymalin is a peptide complex with a longer history in gerontology research.

Frequently Asked Questions
What is Thymalin?
Thymalin is a peptide preparation extracted from the thymus, the gland where T-cells mature. It was developed in the Soviet research program that also produced Epitalon, and it has decades of Russian and Eastern European literature behind it. Research interest is in how it regulates the immune system, particularly the balance between different T-cell populations, and how it behaves in ageing models.
How is Thymalin different from Thymosin Alpha-1?
Both come from the thymus and both are studied for immune function, but they are different things. Thymosin Alpha-1 is one defined 28-amino-acid peptide with a large clinical research base in infection and vaccine-adjuvant models. Thymalin is a peptide complex with a longer history in gerontology and immune-senescence research. Researchers comparing the two usually pick Thymosin Alpha-1 for a defined-molecule study and Thymalin for the ageing and longevity literature.
What does the research show about Thymalin?
The most cited work is the long-term gerontology research where Thymalin, often alongside Epitalon, was studied for immune and endocrine parameters in ageing cohorts. Earlier immunology work studied its effect on lymphocyte maturation and T-cell subset balance. Much of the primary literature is Russian-language, which is worth knowing when searching for it.
How do you reconstitute Thymalin?
Thymalin is supplied as a lyophilized powder and should be reconstituted with bacteriostatic water (BAC water) immediately before use. Inject the BAC water slowly into the vial, directing the stream down the inside wall. Gently swirl to dissolve — do not shake. Once reconstituted, store at 2–8°C and use within 8–12 weeks. For a full step-by-step walkthrough, see our complete peptide reconstitution guide.
How should Thymalin be stored?
Store lyophilized Thymalin vials at -20°C, away from light and moisture. After reconstitution with BAC water, refrigerate at 2–8°C and use within 8–12 weeks. Do not freeze the reconstituted solution.
