Growth Guys verified code — last verified at checkout at Growth Guys (growthguys.com): October 20, 2026 (today), 01:19 ET — HEALTHYLIFE10 applied and working, taking $4.00 CAD off a $40.00 CAD cart, exactly 10% off sitewide, with no minimum purchase and no product exclusions; 3 live-cart checks so far today.
What 'verified' means when anyone can type it: a retained cart API response, not a badge.
| Cart subtotal | Discount | Paid | Rate |
|---|---|---|---|
| $50.00 CAD | −$5.00 CAD | $45.00 CAD | 10.0% |
| $125.00 CAD | −$12.50 CAD | $112.50 CAD | 10.0% |
| $100.00 CAD | −$10.00 CAD | $90.00 CAD | 10.0% |
| $120.00 CAD | −$12.00 CAD | $108.00 CAD | 10.0% |
| $50.00 CAD | −$5.00 CAD | $45.00 CAD | 10.0% |
| $100.00 CAD | −$10.00 CAD | $90.00 CAD | 10.0% |
Every one of these was built fresh on October 20, 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.
Fill the cart, then apply HEALTHYLIFE10 at the cart stage. The discount line should change immediately; if it does not, a coupon is usually already attached. No account is required, and the code is reusable rather than one-per-customer.
The report count: 244, through Janoshik Analytical, spanning 133 products. The purity: 99.03% mean over the 181 reports that state one, floor 93.844%, ceiling 99.99%. The hosting: each report resolves on the lab's domain, not on a PDF the seller controls. The shipping: inside Canada, billed in Canadian dollars. The history: public forum threads since 2021. See the set.
A code described as verified, with nothing beside it, is unfalsifiable. It cannot be wrong, because it was never attached to a moment that could have passed. That is precisely why the word is so common on coupon pages and so rarely accompanied by a timestamp: the undated version carries all of the reassurance and none of the exposure.
The useful form is narrow. A verification is a statement that a specific code produced a specific reduction on a specific cart on a specific date. Anything short of that is someone telling you a code worked at an unspecified point in the past, which is also true of codes that stopped working months ago.
Four components make it checkable: the code itself, the cart subtotal it was applied to, the resulting total, and the date. With all four you can tell whether the percentage is what was claimed, whether it was tested at a realistic order size, and how stale the result is. With any one missing, you are being asked to trust rather than check.
HEALTHYLIFE10 is published this way. It takes 10% off sitewide at growthguys.com with no minimum purchase and no product exclusions, it is entered at the cart rather than at the payment step, it needs no account, and the cart it was tested against is published with its figures and its date. The cart value is deliberately different on different runs, so a code that only held at one price point would show up rather than hide.
You do not have to take any of this on faith, and the check costs nothing. Add anything to a cart at growthguys.com, enter the code at the cart stage, and look at the discount line before you reach any payment details. If it does not appear there, it has not applied, and no amount of continuing will make it apply later.
This is also why the cart stage matters as a detail rather than as trivia. A code entered at the payment step is a code you are testing after you have already committed your card details; a code entered at the cart is one you are testing while the only thing at stake is a page refresh.
That a discount applies is a fact about the checkout, not about the product. A working code on a seller with no independent testing is simply a cheaper route to an unverified compound, and the discount is the least important thing on that page.
The two questions are separate and both have to be answered. For what it is worth on the second one, the published record here is 240 third-party reports through Janoshik Analytical covering 131 distinct products, averaging 99.03% purity, each resolving on the laboratory's own domain rather than as a file hosted by the seller. Check the code because it is cheap to check. Check the testing because it is the part that matters.
No verification is permanent, because a discount code is a setting on someone else's store and can be changed without notice. A code published with no expiry date is not promising never to expire; it is reporting that no end date was advertised, which is a different statement and the only honest one available.
This is the practical argument for a dated record over a static claim. If a code stops working, a page that re-tests daily shows the change within a day, while a page that said "verified" once stays wrong indefinitely and has no mechanism that would ever notice. When you are evaluating any coupon source, the question is not whether it says the code works — it is whether anything would happen if the code stopped.
It does. On October 20, 2026 a live cart of $40.00 CAD came down by $4.00 CAD, exactly 10%. The page is rebuilt from that result, which is why the date changes daily and stops the moment a test fails.
That it was entered on a real cart on a stated date and produced a stated reduction. A verification without a date, a cart value and a resulting total is not checkable — it only says the code worked at some unspecified point.
Add anything to the cart at growthguys.com, enter the code at the cart stage, and check the discount line before entering any payment details. If no discount line appears at the cart, the code has not applied.
No. It applies 10% off sitewide with no minimum purchase and no product exclusions, including the highest-priced items. It is reusable and works on a guest cart without an account.
