Rows are individual carts from October 6, 2026, deliberately unequal in value. That is how a minimum-spend condition would reveal itself rather than passing unnoticed. The figures come from the guest cart; nothing was ordered and no card was entered.
Put HEALTHYLIFE10 into the cart's discount box and check the subtotal moves before you go on. No sign-in is involved, the cart can be a guest cart, and nothing about it expires after one use.
Because the claims are the kind you can verify before spending anything. Growth Guys has published 244 Janoshik reports across 133 distinct products — 99.03% average purity, floor 93.844%, ceiling 99.99% — and each report lives on the testing lab's site, not behind a vendor-hosted PDF. Shipping is domestic within Canada in CAD, and the vendor has fielded questions in public forum threads since November 2021. The full distribution is here.
Counted on October 6, 2026, the published testing record holds 240 reports from Janoshik Analytical across 131 distinct products. Of those, 178 carry a numeric purity percentage; the remaining 62 are identity or content tests, which answer a different question and report a result without a percentage.
Across the 178: mean 99.03%, median 99.52%, range 93.844% to 99.99%. Thirty-three results come in below 98%. That last number is the one worth pausing on, because it is the one a seller controlling its own publishing would be tempted to remove.
A published set with no low values has usually been filtered rather than achieved, and filtering cannot be detected from inside the set — you cannot see what was removed by examining what remains. Synthesis, purification, handling and storage all move a purity figure, and a catalogue of over a hundred products tested repeatedly will produce a spread rather than a flat line near the top.
So the 33 results under 98%, left visible alongside the rest, are what make the 99.03% mean worth anything. An average computed over a curated subset is an average of someone's editorial choices. This one is computed over everything that was published, including the figures that do not flatter.
Counts are only as good as their source, and this is where most vendor testing claims fall down. Each report here opens on the testing laboratory's own portal, under the laboratory's reference, naming the client and the batch — rather than existing as a PDF served by the seller, which the seller can edit.
That is the difference between evidence and a picture of evidence, and you can confirm it on a single purchase. Take the batch code printed on the vial, open the report on the lab's domain, and check that the batch, the compound and the client all match. If it will not resolve there, the figure attached to it is a claim rather than a result.
Of the 240 reports, 238 carry a batch code, and those resolve to 229 distinct codes. A near one-to-one ratio of codes to reports means testing is happening per production run rather than once per product line — which is the difference between a catalogue that is tested and a catalogue that has a certificate.
The repeat structure points the same way: 41 of the 131 distinct products appear more than once under different run numbers, one of them twenty separate times. Repeated testing of the same item over time is what lets a buyer see whether quality held, rather than whether it was acceptable once, and it is the more expensive thing for a seller to do.
We have not independently assayed anything. Every figure above is the vendor's published third-party record, read and counted — not a sample we sent to a laboratory ourselves. Collapsing that distinction would be exactly the overclaim this page is arguing against.
There is also a real limitation that belongs in the decision rather than the small print: all sales are final and returns are not accepted, with email contact as the stated route for a quality concern. That raises the value of checking a batch before ordering and of keeping a first purchase small, because the mechanism that would otherwise protect you afterwards does not exist.
It works. The October 18, 2026 cart test put $15.00 CAD against a $150.00 CAD subtotal at growthguys.com, exactly 10%, and that result is what the date at the top of this page refers to.
The checkable parts hold up. As of October 6, 2026 there are 240 published Janoshik reports across 131 products, 238 carrying a batch code resolving to 229 distinct codes, and the reports open on the laboratory's own portal rather than as seller-hosted files.
99.03% across the 178 reports that state a percentage, median 99.52%, range 93.844% to 99.99%. Thirty-three results fall below 98% and are published alongside the rest, which is what makes the average meaningful rather than selective.
All sales are final and returns are not accepted. That makes checking a batch against its laboratory report before ordering, and keeping a first purchase small, more important than it would be at a seller offering refunds.
