Regulatory status
Methylene blue (methylthioninium chloride) is a prescription-only medicine in many countries. Material sold as a 'research' product is not an approved medicine.
In Canada the regulator is the Health Canada. Rules on buying, importing and using this product differ by country. Suppliers list it for laboratory research; nothing here is medical advice.

Methylene blue (methylthioninium chloride) is a synthetic dye first made in 1876, not a peptide, and the active ingredient of a licensed intravenous medicine for methaemoglobinaemia. At low doses it acts as an alternative electron carrier in mitochondria, which is the basis of its use as a nootropic in small trials of memory, fear extinction and bipolar depression. Its reduced form was tested in large Alzheimer’s trials that missed their primary endpoints. It is a prescription-only medicine with a boxed warning for serotonin syndrome, and the material sold by peptide stores is unlicensed.

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 Methylene Blue is and what published studies have found, see our Methylene Blue 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.
2 of the suppliers PepFinder tracks list Methylene Blue and are based in Canada. The highest rated are VPeptide. The list on this page is ranked by PepFinder Score, which weighs reliability, delivery, pricing, support and customer reviews; stores shipping in from abroad are not included in Canada's prices; nobody pays to be included or to rank higher.
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.
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 Methylene Blue from these suppliers, so check each supplier's own site.
How this list is built: suppliers appear because they list Methylene Blue on their own website, read by our catalogue checks; nobody pays to be included or to move up. Ranking is by PepFinder Score, with stores that have nothing on sale after those that do. Prices, sizes and stock are as each site listed them when checked and may have changed.
