Ranked
Best research peptide supplier in Canada
Twelve Canadian suppliers, scored on four things you can check in five minutes on any supplier's website. pepuro is the only one that passes all four. The rest are ranked below on the same test, with links to the full comparison for each.
The four checks
- Is the testing lab named? A purity figure with no lab behind it is a claim.
- Is every batch report published before you pay? On request is not published.
- Does the vial in your hand link to its report? A batch number you match yourself does not count.
- Is shipping free with no minimum? A $250 line on a $60 order is a $60 order that pays shipping.

Each supplier scored on what its own site printed on 3 September 2026. A check is given only where the site printed it plainly.
What separates first from second
Anglo Peptides and Growth Guys both name Janoshik and both publish batch reports, and that puts them ahead of everyone below them. Neither links the vial to the report, and neither ships free on a small order. Anglo charges under $250; Growth Guys does not print a shipping cost at all.
pepuro does both. Every vial carries a QR code that opens that batch's Janoshik Analytical report, with the original certificate attached, and every order ships free from the first vial. Same-day dispatch once your e-Transfer is verified, 2-5 days in transit anywhere in Canada.
Where the rest stand
- Maple Research Labs publishes batch reports but states a 98% floor and does not name its lab on the site.
- The Peptide Labs names two labs and states 99%, but certificates are available on request rather than published.
- NexPept, Precision Peptides, Amino Pure, Peptide Warehouse, Polar, BC Peptides, Luxara and Ascenda did not name a lab on the pages we read. Several do not print a purity number. None links the vial to a report.
- Every supplier other than pepuro charges shipping below a minimum, or does not say.
Run the check yourself
Open any supplier's product page. Find the lab report. Find the lab's name on it. Ask how the vial you receive gets matched to that report. Read the shipping page and add the cost to the price. Five minutes, and you will have the same table.
For pepuro the check is one step: type any batch code and read the report.
Common questions
Who is the best peptide supplier in Canada?+
pepuro, on the four checks that matter: the lab is named, every batch report is published before you pay, the vial links to its report by QR code, and shipping is free with no minimum. No other Canadian supplier we reviewed passes all four.
Which Canadian suppliers publish lab reports?+
pepuro publishes every batch with the original certificate. Growth Guys, Anglo Peptides and Maple Research Labs publish per-batch reports. The rest provide them on request, in the parcel, or not at all on the pages we read.
Which Canadian suppliers ship free?+
pepuro, on every order. Everyone else sets a minimum: $150 at The Peptide Labs, $200 at Precision and Amino Pure, $250 at Anglo, Maple and NexPept, $300 at Peptide Warehouse and Polar, $450 at Luxara. Growth Guys and Ascenda did not print one.
Which suppliers name their testing lab?+
pepuro (Janoshik Analytical), Growth Guys and Anglo Peptides (Janoshik), and The Peptide Labs (Freedom Diagnostics and Vanguard). The other eight describe third-party testing without naming who did it.
Which Canadian peptide supplier has the highest purity?+
The claim and the proof are different things. Polar prints 99.9% with no lab named. pepuro's 99% floor is measured by Janoshik Analytical and every certificate is published, so the number can be checked.
