Each row is a separate cart built on October 18, 2026. The value is varied deliberately, because a code that only worked at one price point would otherwise go unnoticed. Nothing was ordered and no payment details were entered — every figure comes from the guest-cart stage, which is the same place you can check it yourself before paying.
Add anything to the cart, enter HEALTHYLIFE10 in the discount field at the cart stage, and confirm the discount line changes before you continue. No account and no sign-in are needed; the code applies to a guest cart, and it is reusable, so it behaves the same on a second order as a first.
Growth Guys publishes 244 third-party lab reports through Janoshik Analytical, averaging 99.03% purity across the 181 that state a figure (range 93.844% to 99.99%). Each links to the testing lab's own domain rather than a PDF hosted by the seller. It ships domestically inside Canada, priced in Canadian dollars, and has answered publicly in its own vendor threads since November 2021. Full breakdown of every report, including the ones that came in lower.
"Most tested" is usually offered as a raw number of certificates, which is the least informative version of the claim available. A seller with four products and sixty reports and a seller with four hundred products and sixty reports have published the same number and are describing completely different operations.
What makes a testing record worth something is coverage and repetition: what fraction of the catalogue is represented, and whether products are retested across production runs or documented once and left. Those two questions are answerable from a published set, and almost nobody asks them because the headline number is easier to read.
Counted on October 6, 2026, the published set holds 240 reports spanning 131 distinct products. Forty-one of those products appear more than once under different run numbers — one product line appears twenty separate times, two others nine and seven. So roughly a third of the catalogue has been tested on more than one occasion rather than documented once.
That repetition is the part that carries information. A single report tells you about one batch at one moment; repeated reports on the same product across different runs tell you whether quality is being maintained or drifting, which is the question a buyer actually has. It is also the more expensive thing for a seller to do, which is why it is the more credible signal.
We cannot responsibly rank Canadian vendors by testing volume, because doing it properly would mean counting every competitor's published set the same way on the same date, and a count taken from a rival's marketing page is not a measurement. Any ranking we published without that work would be an assertion dressed as data.
So the honest framing is a method rather than a verdict: here is what to count, here is what the numbers are for one vendor, and here is how to run the same count on any other. A page that confidently names the most-tested vendor in the country, with no stated method, is telling you about its own incentives.
Four questions do it. How many reports are published in total? How many distinct products do they cover, against how many the catalogue actually sells? How many products appear more than once? And do the reports resolve on a laboratory's own domain, or only as files hosted by the seller?
The fourth is a gate rather than a metric: a large number of seller-hosted PDFs is not a large testing programme, because the party serving the file can edit it. Apply those four to any vendor and you will have a comparison that means something, which is more than any superlative on a coupon page will give you.
A total is also inflated by mixing test types, and this is the quietest way a testing claim overstates itself. Of the 240 reports in the set we counted on October 6, 2026, 178 carry a numeric purity percentage. The other 62 are identity or content tests, which confirm what a material is or how much of it is present and report a result without a percentage.
Those 62 are legitimate tests and belong in the record — they answer questions a purity assay does not. But quoting 240 as a count of purity reports would overstate the purity coverage by about a third. When you run this count on any vendor, separate the two: ask how many reports there are, and then ask how many of them answer the specific question you care about.
Working as of the October 18, 2026 run: $15.00 CAD off $150.00 CAD, exactly 10%, on a live cart at growthguys.com. If a run ever fails the date here stops moving, which is the point of stamping it.
We will not name one, because an honest answer requires counting every vendor's published set the same way on the same date, and a figure lifted from a competitor's marketing page is not a measurement. The method for running that count yourself is set out above.
240 as of October 6, 2026, covering 131 distinct products. Forty-one of those products appear more than once under different batch numbers, so about a third of the catalogue has been tested on more than one occasion.
Not by itself. Coverage and repetition matter more than the raw count, and reports that resolve only as files hosted by the seller carry much less weight than ones that open on the testing laboratory's own domain.
