Thymulin

Also known as: FTS · Serum thymic factor · FTS-Zn

Preclinical evidenceEvidence grade C: Preclinical evidence

Grade describes the published research on the molecule. It is not a quality score, a safety score, or a release state.

What this is

Thymulin is a thymic nonapeptide historically called serum thymic factor. Its biological activity is described as zinc-dependent, so peptide identity alone is not a complete material record.

Evidence position

Mechanistic, observational and animal research supports Grade C. The evidence does not support a general clinical claim.

What the record does not establish

A label reading thymulin does not establish zinc association, composition, purity or activity. Those questions require analytical records tied to the exact lot.
