Thymalin
Thymalinum · Thymus peptide complex
A thymus extract used as a medicine in Russia for decades. Not a single defined peptide, which is the fact that governs everything else on this page.
Storage
- Freeze-dried powder
- Refrigerated at 2–8 °C, protected from light.
- After mixing
- Refrigerated at 2–8 °C, and used within days rather than weeks. Biological extracts are less predictable in solution than synthetic peptides.
- Long-term, frozen
- Unopened powder is stable at −20 °C or colder.

When to stop
- Any allergic response: rash, hives, facial swelling or difficulty breathing. Seek urgent care — the animal-derived origin makes this more relevant here than for synthetic peptides.
- A flare of any existing autoimmune condition.
- Fever, or an injection site that becomes hot, spreading or produces pus.
- Swollen lymph nodes that persist.
