Thymalin
A peptide preparation extracted from calf thymus, developed in the 1970s at the Institute of Gerontology in the Soviet Union.

What is being investigated
Directions the published work points at, and how far each has actually got. These are open questions, not established effects: most of what looks promising in cells does not replicate in animals, and most of what works in animals does not work in people. Nothing here is a claim about what this compound does for anyone.
- T-cell differentiation
The mechanism the developing group reported: activation of T-cell maturation, altered recognition of peptide–MHC complexes, and changed cytokine release from blood lymphocytes.
Cell and tissue studies
- Immune decline with age
The thymus shrinks steadily through life, and the clinical work reported by the same group asks whether a thymic extract affects the consequences. Published almost entirely by one institute, which is the limit on it.
Human trials
- Which fraction is active
The question an extract always raises. A dipeptide, L-Glu-L-Trp, was isolated from it as one active component — which is a partial answer rather than a complete one.

Reported that natural and synthetic thymic peptides activated T-cell differentiation and altered cytokine excretion of blood lymphocytes.

- Thymalin: what the research says
A calf thymus extract rather than a defined molecule, with a literature that comes almost entirely from the institute that developed it. Why that matters.
- How to store research peptides
Lyophilised peptides at -20°C, reconstituted at 2–8°C, ambient in transit. Why the dry cake tolerates shipping, and what actually degrades a vial.
- Peptide shelf life and stability
How long lyophilised and reconstituted peptides keep, and the four things that shorten it: temperature, moisture, light and oxidation. Storage figures included.

How to reconstitute a lyophilised peptide with bacteriostatic water without damaging it: why you run the liquid down the vial wall and never shake it.
