At a glance · 25 Sept 2026
Thymalin is a polypeptide extract of calf thymus developed in Leningrad in the 1970s by Vladimir Khavinson and Vyacheslav Morozov, and it has been a registered medicine in Russia for decades as an immunomodulator. It is not a single peptide: it is a mixture from which the dipeptides Glu-Trp (thymogen) and Lys-Glu (vilon) were later identified. Its clinical evidence consists of Russian studies, including a long-running 266-person geroprotection study and non-randomised COVID-19 cohorts, and it is not licensed in the UK, US or EU. Read the full Thymalin guide, with the published research and references.

Price per mg is only half the comparison. Check that the supplier publishes a certificate of analysis for the batch it is selling, ideally from an independent laboratory, and that the certificate confirms identity as well as purity: our guide on how to read a COA shows what to look for. A price far below the rest of the list is more often a warning than a bargain; peptide prices explained sets out why.
For what Thymalin is and what published studies have found, see our Thymalin guide. Handling questions are covered in how to store peptides, and the peptide calculator converts a vial size and water volume into concentration and syringe units. Rules on buying and importing differ by country: read are peptides legal in the US? and see all suppliers serving the US.
How to spot a fake peptide supplier explains each of these in more detail, and third-party peptide testing covers what independent results can and cannot prove.
Most research peptides are sold as freeze-dried (lyophilised) powder in sealed vials, which is mixed with a diluent such as bacteriostatic water before use in the lab. Some suppliers also sell pre-mixed solutions, nasal sprays or capsules under the same name. These are different products with different stability and dosing, so compare price per mg only between the same form, and check which form a listing is before comparing it with the rest of the table.
30 of the suppliers PepFinder tracks list Thymalin and are based in or ship to the US. The highest rated are Bulk Peptide Supply, Direct SARMS, Bulk Peptide Wholesale. The list on this page is ranked by PepFinder Score, which weighs reliability, delivery, pricing, support and customer reviews, with stores based in the US placed before those shipping in from abroad; nobody pays to be included or to rank higher.
Listed prices in USD run from US$1.32/mg to US$8.00/mg, median US$5.10/mg, across 27 listings from 19 suppliers. Compare price per mg rather than price per vial, and only within one currency; a price far below the rest is more often a warning than a bargain.
Suppliers on this page list Thymalin in 5mg, 10 mg, 10mg, 10 MG VIAL, 10mg [3mL], Kit_20mg vial, 10ml bac water, syringes. Most research peptides are sold as freeze-dried powder in sealed vials; capsules, sprays and pre-mixed solutions are different products, so compare price per mg only between the same form.
The FDA treats research peptides sold for human use as unapproved new drugs and has said in 2026 warning letters that research-use-only labels do not change that. Our page on whether peptides are legal in the US sets out the rules with a link to every source. This is general information, not legal advice.
The FDA says it is illegal in most circumstances for individuals to import drugs for personal use, and shipments it considers unapproved drugs can be refused entry. Each supplier on this page shows where it is based, so you can see whether an order would cross a border.
Ask for a certificate of analysis for the batch being sold, and check that it names the laboratory, the batch number and the test date, and that it confirms identity by mass spectrometry as well as purity by HPLC. PepFinder has not yet collected certificates for Thymalin from these suppliers, so check each supplier's own site.
How this list is built: suppliers appear because they list Thymalin on their own website, read by our catalogue checks; nobody pays to be included or to move up. Ranking is by PepFinder Score. Prices, sizes and stock are as each site listed them when checked and may have changed. Provisional scores are based on incomplete research.
