TB-500 is a synthetic seven-amino-acid peptide, Ac-LKKTETQ, copied from the actin-binding region of the natural protein thymosin beta-4. Most of the research people cite for TB-500 was done with full-length thymosin beta-4, not with TB-500 itself. TB-500 has not been tested in any published human trial and is not an approved medicine. Read the full TB-500 guide, with the published research and references.

The median listed price per mg across every tracked supplier listing TB-500 in each currency, recorded daily from validated listings only. Days with too few listings to publish are left out, not estimated. How we validate prices
CAD · median per mg
No validated daily statistics yet. A trend appears once there is more than one day of data.
Catalogue changes, last 30 days
No TB-500 listings added or withdrawn since we began recording catalogue changes.
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 TB-500 is and what published studies have found, see our TB-500 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 Canada? and see all suppliers serving Canada.
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.
14 of the suppliers PepFinder tracks list TB-500 and are based in or ship to Canada. The highest rated are Panda Peptide, PeptideProCanada, Reviv Peptides. The list on this page is ranked by PepFinder Score, which weighs reliability, delivery, pricing, support and customer reviews; nobody pays to be included or to rank higher.
Listed prices in CAD run from CA$6.30/mg to CA$16.00/mg, median CA$8.00/mg, across 19 listings from 10 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 TB-500 in 2mg, 5MG, 5 mg, 5mg, 5mg / Single vial, 10MG. 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.
Health Canada says unauthorised drug products, including peptides it names such as BPC-157, TB-500 and ipamorelin, are illegal in Canada, and that research-use-only labels do not make them legal. Our page on whether peptides are legal in Canada sets out the rules with a link to every source. This is general information, not legal advice.
Residents generally cannot bring prescription drugs into Canada, and Health Canada says non-compliant products found at the border will be refused entry or seized. Each supplier on this page shows where it is based, so you can see whether an order would cross a border.
Yes. TB-500 is named in the 2026 World Anti-Doping Agency Prohibited List, which applies to athletes in tested sports at all times, in and out of competition. A research-use-only label is no defence to a positive test.
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 TB-500 from these suppliers, so check each supplier's own site.
How this list is built: suppliers appear because they list TB-500 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.
