What is Thymalin?

The thymus produces factors that take part in the maturation of immune cells. Thymalin is a peptide fraction derived from that gland; being a mixture, it is characterized by its origin and profile rather than by a single defined sequence.

Research context

The literature on Thymalin has focused on modulating the immune response and on studies related to immune system aging in experimental models.

These findings belong to the field of research and do not constitute evidence of efficacy in humans. Thymalin is offered for research use only.

Handling and reconstitution

See the reconstitution guide and the storage guide.

Quality and traceability

≥99% purity by HPLC and batch COA. See quality control.

Frequently asked questions

What is Thymalin?

It is a mixture of thymus-derived polypeptides, studied in research as an immunomodulator.

Why is it described as a mixture and not a single sequence?

Because Thymalin is a peptide extract of the thymus gland, characterized by its origin and profile rather than by a single defined sequence.

Is Thymalin approved for human consumption?

No. Thymalin is offered exclusively for laboratory scientific research use; it is not approved by COFEPRIS or intended for human or animal consumption.

What purity and backing does NeoPeptidos' Thymalin have?

Each batch is delivered with ≥99% purity verified by HPLC chromatography and a Certificate of Analysis (COA) issued by an independent laboratory.
