What Melatonin is
Melatonin is a hormone made by the pineal gland from tryptophan, via serotonin, that signals darkness to the body clock. It is not a peptide, but peptide stores sell it in 10 mg and 20 mg capsules, drops and occasionally vials alongside sleep peptides such as DSIP. Meta-analyses find it shortens the time taken to fall asleep by a few minutes and adds a few minutes of sleep, it helps jet lag when timed to the destination bedtime, and it is a prescription-only medicine in the UK but a freely sold supplement in the US. Read the full Melatonin guide, with the published research and references.

Before you choose a Melatonin 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 Melatonin is and what published studies have found, see our Melatonin 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.
Checking a Melatonin certificate of analysis
- The certificate names a laboratory you can find independently, and ideally one with no stake in the result.
- It carries a batch or lot number that matches the product page or the vial label, and a test date.
- It confirms identity by mass spectrometry, not only purity by HPLC. Purity alone does not show the vial contains Melatonin.
- It includes the chromatogram and mass spectrum, not just a summary table.
- 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.
Melatonin in Canada: questions
Where can I buy Melatonin in Canada?
1 of the suppliers PepFinder tracks list Melatonin and are based in or ship to Canada. The highest rated are MECP. The list on this page is ranked by PepFinder Score, which weighs reliability, delivery, pricing, support and customer reviews, with stores based in Canada placed before those shipping in from abroad; nobody pays to be included or to rank higher.
What sizes is Melatonin sold in?
Suppliers on this page list Melatonin in 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.
Is it legal to buy Melatonin in Canada?
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.
Can Melatonin be shipped to Canada?
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.
How do I check a Melatonin 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 Melatonin from these suppliers, so check each supplier's own site.
How this list is built: suppliers appear because they list Melatonin 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.
