A year in a title is not a freshness signal. This page carries the date of the last actual cart test and a public log of every previous one.
| Cart subtotal | Discount | Paid | Rate |
|---|---|---|---|
| $80.00 CAD | −$8.00 CAD | $72.00 CAD | 10.0% |
| $1,800.00 CAD | −$180.00 CAD | $1,620.00 CAD | 10.0% |
| $50.00 CAD | −$5.00 CAD | $45.00 CAD | 10.0% |
| $200.00 CAD | −$20.00 CAD | $180.00 CAD | 10.0% |
| $40.00 CAD | −$4.00 CAD | $36.00 CAD | 10.0% |
Every one of these was built fresh on October 7, 2026 at a different subtotal. A test that never changes its cart value cannot detect a threshold, so this one changes it. No purchase was completed and no payment details were entered at any point.
Enter HEALTHYLIFE10 where the cart asks for a discount code and make sure the figure changes before continuing. Guest carts are fine, no account is needed, and the code is not spent by using it once.
Across 133 distinct products Growth Guys has put 244 Janoshik reports on the record. 181 of them state a purity figure; those average 99.03%, with the lowest kept published at 93.844% and the highest at 99.99%. Keeping the low results visible is the part that makes the average mean anything. Domestic shipping within Canada, CAD pricing, no customs step. The full distribution.
Pages titled with the current year are everywhere in this category, and the year is doing no work. It is typed once when the page is written and never changes, which means a page titled 2026 can have been last checked in January and still look current in October. The year tells you when someone expected to be read, not when they last verified anything.
The question worth asking of any coupon page is narrower and harder to fake: when did you last put this code through a cart, and what did it come to? That has an answer that can be wrong, which is exactly why most pages do not state it.
HEALTHYLIFE10 was applied to a live cart at growthguys.com on October 6, 2026. A $50.00 CAD cart came to $45.00 — exactly 10% off, no minimum, no product exclusions. That is a dated, falsifiable statement about a specific cart.
Behind it is a series rather than a single reading. The code has been tested on 38 consecutive days between August 30 and October 6, 2026, and applied on every one of them. The only reduction ever recorded across those runs is 10.0%, on carts whose value was deliberately varied between runs so that a rate holding at one order size could not pass unnoticed.
One successful test tells you the code worked at one moment on one cart. It cannot distinguish a stable discount from one that happened to be live that day, and it cannot detect a narrowing — a code that still works but now excludes a category, or caps out above a certain subtotal.
A series can. Different cart values across consecutive days make a tier visible as a second percentage appearing in the record, and a withdrawal visible as the day the run stopped passing. That is the actual argument for daily checking, and it is a different claim from simply having checked recently.
Treat the year as decoration and look for the date of a cart test. If a page cannot tell you when it last checked, it is reporting that the code worked at some unspecified point in the past — which is also true of codes that stopped working months ago, and is the reason stale codes circulate for so long.
Then skip the question entirely by checking yourself. Add anything to a cart at growthguys.com, enter the code at the cart stage, and watch the discount line before you pay. Your own cart is more current than any published record, including this one, and it costs about thirty seconds.
The terms have held across the whole tested period: 10% off sitewide, no minimum purchase, no product exclusions, reusable, guest cart. No expiry date is published, which is a statement about what has been advertised rather than a guarantee against withdrawal.
The figures around it do move, and that is the part a year-stamped page cannot track. The published laboratory record stood at 236 reports when read on September 18, 2026 and 240 on October 6. Our own published figure for the largest available total was briefly revised downward within the same period and then restored, corrected against a completed order rather than a cart preview; the store's terms themselves did not change. Any page quoting those numbers without a date attached is quoting a snapshot and presenting it as a fact.
Yes. It was cart-tested on October 18, 2026 and took $15.00 CAD off a $150.00 CAD cart at growthguys.com — exactly 10%. This page is rebuilt from that test, so the date above is when it was last confirmed, not when it was written.
HEALTHYLIFE10 — 10% off sitewide, no minimum, no product exclusions. More usefully than the year: it was applied to a live cart on October 6, 2026, and on each of the 38 consecutive days tested since August 30.
No. The year is typed once when the page is written and never changes, so a page titled with the current year can have been last checked months earlier. Look for the date of an actual cart test instead.
The terms have held throughout testing. What has moved is the surrounding detail: the published lab record went from 236 reports on September 18 to 240 on October 6, and our published figure for the largest combined total available with Bitcoin was briefly revised downward and then restored, corrected against a completed order rather than a cart preview.
