What is Thymalin?

Thymalin was developed from thymus gland extracts as part of early bioregulator research into restoring immune function, making it one of the older thymic peptide preparations still referenced in the literature. Unlike single-sequence synthetic peptides, it is a complex mixture of low-molecular-weight polypeptides rather than one defined molecule.

How it is understood to work

Thymalin is studied for its reported ability to help normalize the balance of T-lymphocyte subpopulations and stimulate cellular immunity, with proposed effects on the regenerative capacity of thymic and broader immune tissue. Because it is a mixed extract rather than a single peptide, its exact molecular mechanism is less precisely defined than that of purified synthetic peptides.

Research status

Thymalin has a decades-long research history, including use in Eastern European clinical and preclinical studies of immune deficiency and immune aging, though much of this literature has not undergone the level of independent, international peer review applied to newer synthetic peptides; it is not an approved therapeutic in the United States.

Lab testing

There is no public lab report for this listing yet. We can ask the brand for the batch COA before you order. Many buyers also split an independent HPLC test with others who bought the same batch.

Request the batch COA · How group testing works

Bought through escrow: the brand is only paid after you confirm delivery. If the parcel never arrives, or an independent test shows the wrong compound or a significant under-fill, open a claim before releasing payment.

Specifications

Compound: Thymalin
Also known as: Thymic Polypeptide Complex
Class: Thymus-derived polypeptide complex (immune bioregulator)
Form: Lyophilized (freeze-dried) powder
Per vial: 10mg
Type: Thymic polypeptide complex (bioregulator)
Stated purity: ≥99% (HPLC)
Appearance: White lyophilized powder

Handling & storage

Supplied as a lyophilized powder; store unopened vials at -20C protected from light, and once reconstituted with bacteriostatic water keep refrigerated at 2-8C for use within the study’s defined timeframe.

Concentration check: adding 2 ml of bacteriostatic water to one 10 mg vial gives 5 mg/ml. The Research Lab calculator in your dashboard works this out for any volume.

Questions

Is Thymalin a single peptide or a mixture?

It is a complex of multiple low-molecular-weight polypeptides extracted from thymus tissue rather than one chemically defined sequence, which distinguishes its characterization and testing from single-sequence synthetic peptides.

What should a COA for Thymalin show, given it is a complex rather than a single molecule?

Because there is no single molecular weight to confirm, a meaningful COA will report overall HPLC purity and batch consistency data from an independent lab rather than a single mass-spec identity match, since the product is a defined mixture rather than one pure compound.

How much Thymalin is in this kit?

10 vials of 10 mg each, so 100 mg in total. The lab testing section above shows what the brand’s tested vial actually contained.
