Is Growth Guys the same company as growth guy — last verified at checkout at Growth Guys (growthguys.com): October 21, 2026 (today), 02:07 ET — HEALTHYLIFE10 applied and working, taking $8.00 CAD off an $80.00 CAD cart, exactly 10% off sitewide, with no minimum purchase and no product exclusions; 3 live-cart checks so far today.
Several unrelated businesses use near-identical names, and coupon aggregators merge them. A code listed under one does nothing at the other, which is why 'verified' listings fail at the cart.

Every row above is its own cart, built on October 21, 2026 at a different value on purpose: a code that held at one price and failed at another would look identical to a working one if the test never moved. No order was placed and no payment details were entered; all of it comes from the guest cart, which anyone can reach.
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.
Three things, none of which require trusting anyone. The testing: 244 reports covering 133 products, each hosted on the lab's own domain rather than the seller's, averaging 99.03% and ranging 93.844% to 99.99%. The logistics: orders leave from inside Canada and are priced in Canadian dollars, so there is no customs step and no conversion. The history: public vendor threads answerable since 2021. We counted every report, weaker results included.
A Canadian research-compound vendor, a business-coaching company, a supplements brand and a UK garden retailer all trade under names separated by a word or a letter. None of them is the other, none shares ownership, and none honours the others' discount codes.
This matters because it is the most common reason a code described as verified does nothing at checkout. The listing was accurate about a company — just not the one the reader was buying from.
Aggregator pages are assembled by matching names. A code issued by the coaching company appears on a page headed with the vendor's name, sometimes beside a percentage that company really does offer. Nothing about the listing is fabricated; the association is.
The checkout is the thing that resolves it. A code belonging to another business is refused, and no amount of confident listing changes that. If a code fails, the first question is whose code it actually was.
Check the domain the listing points at rather than the brand name it displays. Check whether the described products match what you are buying — a 15% coaching package discount and a sitewide code at a compound vendor are not the same offer wearing different numbers.
Percentages are a useful tell. Where one business consistently offers a rate no code at the other has ever returned, a listing quoting that rate is almost certainly about the other business.
HEALTHYLIFE10 applies at growthguys.com, the Canadian research-compound vendor that ships domestically and publishes third-party purity testing through Janoshik Analytical. It applies 10% off sitewide with no minimum purchase and no product exclusions, including the highest-priced items.
It does nothing at any of the similarly named businesses, and their codes do nothing here. That is not a criticism of them; it is what separate companies means.
Ambiguity benefits whoever is listed first, and on a name this crowded that is frequently not the business a reader meant. Writing out which company a code belongs to costs nothing and removes the most common failure at checkout.
It is also the honest position for a page that is paid when an order completes: a reader who buys from the wrong company has been failed by the listing, not by the code.
Yes. The most recent check was October 21, 2026: $120.00 CAD off a $1,200.00 CAD cart at growthguys.com, a clean 10%. Nothing here is asserted from memory — the figures come out of that day's test.
No. HEALTHYLIFE10 applies at growthguys.com only. Businesses with similar names are unrelated and do not honour each other's codes, which is why a code copied from an aggregator listing frequently fails at checkout.
Because those pages are assembled by matching brand names rather than by testing. The listing is usually accurate about some company — just not the one the reader is buying from.
Check the domain the listing links to, not the brand name shown, and check whether the products described match what you are buying. A discount on coaching packages and a sitewide code at a compound vendor are different offers.
