Thymalin 10mg (10 Vials / Kit)

Thymalin at a glance

Thymalin is a preparation of polypeptides isolated from calf thymus, developed in the Soviet Union by researchers including Vladimir Khavinson and Vyacheslav Morozov. It is not one defined sequence but a mixture of small peptide fractions, which sets it apart from synthetic single-molecule products in this catalogue. The material is supplied as white lyophilized powder. Work on the extract later led to synthetic short peptides such as Thymogen, which were intended to capture part of its activity in a defined form.

Price and availability

Sold by Sulan Bio and sent from Guangzhou, China, this listing is a kit of 10 vials at 10mg each (100 mg in total). $90.00 buys the whole kit, which is $0.90/mg. Across 5 brands listing Thymalin here, the middle half of prices falls between $0.55 and $0.603 per mg; this kit is above the typical range. Funds stay in escrow and are released to Sulan Bio only when you mark the order as received.

What it is studied for

Studies from the developing institutions describe Thymalin as restoring the ratio of helper and suppressor T-cell subsets, increasing markers of T-cell maturation and supporting phagocytic activity in models of immune suppression. One proposed explanation is that its short peptides influence gene expression in thymic and lymphoid cells, in line with the model later applied to synthetic bioregulators. Because the product is a mixture, it is difficult to assign activity to any single component, and the molecular targets behind these observations remain poorly defined.

Research and regulatory status

Thymalin has been used clinically in Russia, and its literature includes decades of animal work along with human observational and small controlled studies, many reported in Russian-language journals. Long-term follow-up studies in older adults have been published by the originating group. Independent international replication is sparse, and it is not approved in the United States or the European Union. On GLP1 Forum Escrow it is listed for research use only.

Checking the lab data

A mixture cannot be confirmed by one mass peak. A credible report would show an HPLC profile or fingerprint compared against a reference, total protein or peptide content, and a molecular-weight distribution, for example by size-exclusion chromatography. Some labs add mass spectrometry of the major components. Appearance should be a white lyophilized powder, and the report should state the claimed source tissue, the batch number and the testing date.

Storage and preparation

Keep unopened freeze-dried vials cold, sealed and out of the light; moisture is what degrades a lyophilized cake fastest. After reconstitution, refrigerate the solution and work within the stability window your protocol sets.

Concentration arithmetic: one 10 mg vial dissolved in 2 mL gives 5 mg/mL, or 10 mg/mL in 1 mL. The Research Lab calculator in your dashboard handles any other volume.
