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

A kit of 30 vials at 10mg each (300 mg in total) from Jinlu Peptides, shipped from China. The price is $180.90, or $0.603 per milligram of peptide. Across 5 brands listing Thymalin here, the middle half of prices falls between $0.55 and $0.603 per mg; this kit is inside that range. Funds stay in escrow and are released to Jinlu Peptides only when you mark the order as received.

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.

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.

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.

This listing has no third-party report on file yet. The lab reports directory and the Thymalin page show which brands do publish testing.

Storage and preparation

Freeze-dried peptide keeps best sealed, cold and dark. Once it has been dissolved, refrigerate it, avoid repeated warming and follow the stability limits in your study protocol.

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.

Buyer questions

How does Thymalin relate to thymosin alpha-1?

Both are linked to the thymus, but they are different products. Thymosin alpha-1 is a single defined peptide originally purified from a thymic extract and now made synthetically, while Thymalin remains a multi-component extract. Evidence for one should not be applied to the other, and their analytical testing requirements differ substantially.

Why is source-tissue origin relevant for an extract like this?

Because Thymalin is purified from animal thymus rather than assembled residue by residue, its composition depends on the starting tissue and the extraction process. Batch-to-batch variation is therefore more likely than with synthetic peptides, and buyers benefit from reports that compare each lot's profile against a consistent reference.

How much Thymalin is in this listing?

30 vials of 10mg each — 300 mg in all. Where a lab report exists, the testing panel above shows what the brand's tested sample actually measured.

When does Jinlu Peptides get paid?

Only after you confirm delivery. Until then the payment is held in escrow, and you can open a claim if anything is wrong with the order.
