Thymalin: What It Is and Its U.S. Regulatory Status

What is Thymalin?

Thymalin is not a single peptide. It is a complex of peptides extracted from the thymus gland of calves. The thymus is a small organ in the chest that plays a role in the development of the immune system, especially T cells.

Thymalin was developed by researchers in the former Soviet Union and is registered as a medicine in Russia. Registration in another country does not make a product approved in the United States.

U.S. regulatory status

Current status: Not FDA-approved.

Thymalin is not the active ingredient in any FDA-approved medicine, and the FDA has not found it safe and effective for any use in people.

Because it is an animal-derived extract, its exact makeup is harder to define than that of a single synthetic peptide.
