What Glutathione is

Glutathione is a tripeptide made of glutamate, cysteine and glycine that every cell uses as an antioxidant. It is sold as injectable vials, IV drips, capsules and creams, most often for skin lightening. Small trials suggest oral and topical glutathione can modestly lower skin melanin, but there is almost no controlled evidence for glutathione injections for skin lightening, and the US FDA and the Philippine FDA have warned against them. Read the full Glutathione guide, with the published research and references.

Before you choose a Glutathione supplier

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 Glutathione is and what published studies have found, see our Glutathione 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: see legal status by country, or narrow this list to your region above.

Checking a Glutathione certificate of analysis

  1. The certificate names a laboratory you can find independently, and ideally one with no stake in the result.
  2. It carries a batch or lot number that matches the product page or the vial label, and a test date.
  3. It confirms identity by mass spectrometry, not only purity by HPLC. Purity alone does not show the vial contains Glutathione.
  4. It includes the chromatogram and mass spectrum, not just a summary table.
  5. Where the laboratory offers online verification of its reports, the report number checks out.

Red flags

  • No certificates at all, or certificates available only “on request”.
  • The same certificate used for several products or several years of stock.
  • Payment only by cryptocurrency or bank transfer, with a discount for paying that way.
  • A price far below every other supplier on this page.
  • No company name, address or way to contact the business other than a web form.
  • Vials labelled only with a code rather than the product name and strength.

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.

Vials, capsules and pre-mixed products

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.

141 of the suppliers PepFinder tracks list Glutathione. The highest rated are UK Peptides Online, Bulk Peptide Supply, BioPep. 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.

How much does Glutathione cost?

Listed prices in USD run from US$0.01/mg to US$0.57/mg, median US$0.05/mg, across 92 listings from 58 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.

What sizes is Glutathione sold in?

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.

Is Glutathione legal to buy?

It depends on the country. PepFinder summarises the rules for the UK, the US, Canada, Australia, New Zealand and Europe, with links to the regulators' own statements. Choose a region above to see suppliers and the rules for that country.

How do I check a Glutathione supplier's test results?

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 Glutathione from these suppliers, so check each supplier's own site.

How this list is built: suppliers appear because they list Glutathione 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.
