Thymosin Alpha-1 vs TB-500
The shared word 'thymosin' causes more confusion than any other naming overlap in this catalog. They are not variants of each other.
What is the difference
Both names come from thymosin fraction 5, a crude thymus extract that early researchers separated by acidity, alpha, beta and gamma fractions. That shared origin story is where the relationship ends. Thymosin alpha-1 is a 28-amino-acid peptide cleaved from prothymosin alpha and studied in immune signalling. TB-500 is a synthetic fragment of thymosin beta-4, an actin-binding protein studied in tissue research. Different precursors, different sequences, different research fields. And a common reason people order the wrong one.
| Property | Thymosin Alpha-1 | TB-500 |
|---|---|---|
| Precursor | Prothymosin alpha | Thymosin beta-4 |
| Length | 28 amino acids | Short synthetic fragment of Tβ4 |
| Studied in | Immune signalling, dendritic cells, T-cell differentiation, TLR9 | Tissue research, actin binding, cell migration |
| Naturally occurring | Yes, in the thymus | The parent protein is; TB-500 is a synthetic fragment |
| Also known as | Thymalfasin, a licensed medicine in some countries | Thymosin beta-4 fragment |
| Formats | 5 mg and 10 mg vials | 10 mg vial |
| VND price (this catalog) | from 1,950,000 VND | 2,200,000 VND |
Bottom line
If you are choosing between these two, the family name is the least useful thing about them. Immune-signalling research points to thymosin alpha-1; tissue and cell-migration research points to TB-500. Check the format before ordering, both are in the catalog.

Common questions
Which of these peptides is better for research?
Neither is "better". Thymosin Alpha-1 and TB-500 address different research questions through different mechanisms. The choice depends on the research protocol.
Can I order both peptides from this catalog?
Yes. Thymosin Alpha-1 and TB-500 are listed as separate items. 2+ peptides = free bacteriostatic water 10 ml. Price and availability confirmed before payment.
Do I need a separate inquiry for each peptide?
No. You can ask about both in one Telegram message. Mention the names and formats. The manager will confirm availability, total and timing.
