Peptides Canada — Research Peptide Catalogue, Lot COAs and Purity Records (RUO)

Peptides Canada, in one line: Hermetica Research Labs lists eight research peptides and one laboratory water across ten Research Use Only catalogue lines, ships to Canadian addresses only, and publishes seven lot-matched third-party certificates. This hub is the catalogue-and-documents entry point for Canadian laboratories: what is stocked, which lot each vial comes from, who tested it, and how to check the paperwork. It gives no usage information of any kind.

Key takeaways

Canadian peptides catalogue: stock, lot and laboratory

The table below is taken from the published Certificates of Analysis index. Where no certificate is published, the table says so rather than implying one exists.

Prices are shown on each product page and in the shop; the product page always governs. Each compound also has a Canada page: BPC-157, TB-500, Retatrutide, GHK-Cu, MOTS-c, Epitalon, DSIP and bacteriostatic water.

Pure peptides in Canada: what purity on a COA means

"Pure peptides" and "purity" searches usually mean one number on a certificate, but that number has a narrow meaning. HPLC purity is the share of the target peptide among the components the method detects in the assayed sample. D'Hondt et al. (2014) describe the related impurities that purity methods are built to separate, such as deletion sequences and oxidation or hydrolysis products. Purity is not peptide content by weight: synthetic peptides commonly carry counter-ions such as trifluoroacetate (TFA), and Erckes et al. (2025) set out why TFA content is analysed and reported separately. That is why some certificates also give a measured content figure, for example 11.28 mg on the BPC-157 report and 11.34 mg net peptide content on the Retatrutide report.

Three checks make a purity figure meaningful in a lab file:

1. One lot, one number. The figure belongs to the named lot or batch only. Hermetica's range across published lots is 99.496% to 99.86%.
2. A named laboratory. Janoshik Analytical or Freedom Diagnostics here, with a report number you can look up.
3. A matching vial. The lot printed on the vial label is the lot on the certificate.

Why research peptides ship as lyophilized powder

Every peptide in the catalogue is supplied as a lyophilized (freeze-dried) powder. Wang (2000) describes lyophilization as the most common way to prepare solid protein and peptide materials because they have limited stability in solution; a dry solid ships and stores more reliably, though it is not stable indefinitely. Storage records for lyophilized vials are covered in research peptide storage and handling.

How to compare Canadian peptide suppliers

Many Canadian peptide sites look alike. The differences show up in the documentation, so these are the checks worth recording for any supplier, including this one:

What a Canadian lab file should contain

1. Product page identity fields recorded against the SKU ordered.
2. The vial label lot or batch number.
3. The lot-matched COA, with the issuing laboratory name and report or accession number.
4. The order confirmation, packing slip and shipping record.

Peptides not stocked (identity notes only)

These compounds are often searched alongside Canadian peptides. Hermetica does not stock them; the pages below are identity and certificate-review notes only, with no price or SKU: tesamorelin, ipamorelin, CJC-1295 / ipamorelin, KPV, sermorelin, AOD-9604, tirzepatide and KLOW.

Research Use Only scope

Every peptide in this catalogue is supplied as a laboratory reagent for in-vitro and analytical work. It is not for human or veterinary use, not for diagnostic or therapeutic procedures, and sold only to purchasers aged 21 or older. Nothing on this site describes amounts, routes, effects or outcomes in people or animals.
