What separates first from second
Anglo Peptides and Growth Guys both name Janoshik and both publish batch reports, and Align Biosciences names two labs and publishes a PDF per batch. That puts the three of them ahead of everyone below. None links the vial to the report, and none ships free on a small order. Anglo charges under $250, Align under $400, and Growth Guys does not print a shipping cost at all.
pepuro does both. Every vial carries a QR code that opens that batch's independent lab 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 and links to its lab, Testides, but states a 98% floor, charges shipping under $250 and puts nothing on the vial.
- The Peptide Labs names two labs and states 99%, but certificates are available on request rather than published.
- Durham Peptides names Janoshik and states 99%+, but certificates are on request, the lab-results page lists none, and shipping is $15 under $200.
- 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. No vial yet? Open the Lab Reports tab on any product page and enter your email; the latest batch’s report comes to you.
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 (open the Lab Reports tab on any product page and enter your email for the latest one), 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, Maple Research Labs and Align Biosciences publish per-batch reports. Durham Peptides provides certificates on request. 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, Amino Pure and Durham Peptides, $250 at Anglo, Maple and NexPept, $300 at Peptide Warehouse and Polar, $400 (or any 5-pack) at Align Biosciences, $450 at Luxara. Growth Guys and Ascenda did not print one.
Which suppliers name their testing lab?
+
pepuro (Janoshik Analytical and other independent labs), Growth Guys and Anglo Peptides (Janoshik), The Peptide Labs (Freedom Diagnostics and Vanguard), Maple Research Labs (Testides, linked from its certificates page and printed on every report), Align Biosciences (PPB Analytical Inc. and Testides, on its certificates page) and Durham Peptides (Janoshik, in its FAQ). The other seven 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 an independent third-party lab such as Janoshik Analytical and every certificate is published, so the number can be checked.
