Canada research peptide supplier report, September 2026

Key findings

1. 01

   86 stores sell to buyers in Canada. 16 are based in Canada and 70 ship in from abroad: 1 from Denmark, 33 from the UK, 1 from Lithuania, 8 from the US and 27 that do not say where they are based.

2. 02

   69% of stores based in Canada say their products are third-party tested; none of those claims has been checked yet. 11 of the 16 stores based in Canada (69%) say on their own website that their products are third-party tested, and 9 link a page of certificates of analysis. PepFinder has not yet reviewed a certificate from any store serving Canada, and one store serving Canada has passed a PepFinder staff check. These are the stores' statements, not results we have confirmed; stores may hold certificates we have not seen.

3. 03

   Most listings sold to Canada are priced in other currencies. These stores list 3,803 products, but only 988 are priced in CAD; the other 2,815 are in other currencies and are left out, never converted. Of the 988 CAD listings, 730 (74%) state a price, form and quantity we can compare.

4. 04

   The same peptide sells at very different prices. Retatrutide is the most widely listed: the middle half of 42 single-vial listings from 13 stores runs from CA$6.36 to CA$9.00 per mg (median CA$7.50), and the most expensive is 2.7 times the median. A 10 mg vial, the size most often listed, has a median listed price of CA$90.00. Part of any per-mg spread is vial size, since larger vials usually cost less per mg.

Which prices can be compared

Every listing priced in CAD by a store serving Canada, by what we could read from it. Only the first row enters any price figure. 2,815 more listings from these stores are priced in other currencies and are not included.

Of the 730 compared prices, 691 are single vials and 39 are packs of several vials. The price figures below use single vials only, so a bulk price is never set against one vial.

How the figures are built

Stores serving the region

Published, active suppliers based in the market or stating they ship to it.

Based in the region

The supplier's recorded country is in the market.

Third-party testing

What the supplier's own website states. 'stated' is a claim, not a verified result; 'notFound' means we read the site and found no such statement; 'notAssessed' means not yet read.

Certificates page

The supplier's site links a page of certificates of analysis. Not a check of any certificate.

Certificates reviewed

Suppliers with at least one certificate PepFinder holds and has reviewed.

PepFinder check

Suppliers with a PepFinder staff verification check passed and not expired.

Compared price

Listed price in the market currency whose form, total mass and currency we could read with confidence, not held for review and not an outlier. Only VALID prices enter the distributions.

Single vial

One vial of powder of one peptide. Packs of several vials, pens, capsules, sprays, kits and blends are excluded from the distributions.

Minimum sample

A peptide is reported once it has at least 5 listings from 3 suppliers.

One business, several sites

A business trading through several confirmed storefronts is counted once per identical listing.

Prices are listed prices as each store's site showed them when last checked, without shipping or tax. Nothing here describes what the products do or how they are used; they are sold for laboratory research. How we collect and validate prices · Legal status in Canada.
