Thymosin Alpha-1

Thymosin Alpha-1 and Thymalin, side by side

Thymosin Alpha-1 is a 28-amino-acid peptide first isolated from thymus tissue, where it takes part in signalling between immune cells. A synthetic version, known as thymalfasin, has been approved as a medicine in a number of countries, though not in the United States, and the peptide is widely studied in immune-modulation and inflammation research. The materials on this page are research-grade products, not that licensed medicine. This page also covers Thymalin, a related thymic preparation from the Russian bioregulator tradition. The two are different products: Thymosin Alpha-1 is a single defined peptide, while Thymalin is described as a thymic peptide extract. Each listing states which one it is, along with the brand, milligrams per vial, vial count and price per milligram. Independent lab reports are attached where brands have provided them, which is especially helpful for confirming identity between two similar-sounding products. Payment goes into escrow rather than to the brand. It stays there until your order is delivered and is released only afterwards; any claim opened before release is reviewed with your money still held.

Frequently asked questions

How does Thymosin Alpha-1 differ from Thymalin?

Thymosin Alpha-1 is a single, defined 28-amino-acid peptide. Thymalin is a thymic peptide preparation from the Russian bioregulator tradition, described as an extract rather than a single molecule. Both are studied in immune research and both appear on this page, each clearly labelled.

Is Thymosin Alpha-1 approved as a medicine?

A synthetic version called thymalfasin has been approved in a number of countries, though not in the United States. The products on GLP1 Forum Escrow are research-grade materials from independent brands, sold for laboratory study only, and the site does not give medical advice.

Is there a fee on top of the Thymosin Alpha-1 price?

Yes. An escrow and service fee is added at checkout and shown as a separate line. It funds sourcing, escrow protection and support. If a claim is upheld in full, the fee is refunded together with the order amount to your Escrow Wallet.
