Growth Guys promo code, verified October 11, 2026: HEALTHYLIFE10 takes 10% off sitewide at Growth Guys (growthguys.com) on any payment method, and it is the code behind the largest total discount available there today — 30% off when the order is paid with Bitcoin, which the store discounts a further 20% automatically, so a $430.00 CAD cart paid $301.00 CAD. The measured cart, line by line.
Last verified at checkout at Growth Guys (growthguys.com): October 11, 2026 (today), 15:31 ET — HEALTHYLIFE10 applied and working, taking $4.00 CAD off a $40.00 CAD cart (TB-500 5mg), exactly 10% off, with no minimum purchase and no product exclusions, including HGH kits; 2 live-cart checks so far today.
HEALTHYLIFE10 takes 10% off sitewide at Growth Guys (growthguys.com) with no minimum purchase and no product exclusions, with no minimum purchase and no product exclusions. It was applied to a real cart on October 8, 2026: $50.00 CAD became $45.00 CAD, exactly $5.00 CAD off. That test is entry number 126 in a series running 40 days, and every entry in it is published.
This page answers the three questions people actually type — whether you searched for a Growth Guys promo code, a Growth Guys discount code, or a Growth Guys coupon code, the answer is the same code and the same evidence, so they are answered together here rather than split across three pages that each tell you less.
Any page can tell you a code works. Almost none tell you when they last checked, which makes the claim impossible to disprove and therefore worth nothing. A coupon listing that cannot be falsified is not evidence; it is an assertion with a number in it.
So the standard we hold ourselves to is narrower and duller than "verified", and it has four parts. A claim about a discount code is worth something only if: it is dated to the moment of the test; the cart value changes between tests, so a code that works only at one price point is caught rather than hidden; failures are published alongside passes; and the series is tamper-evident, so nobody — including us — can quietly rewrite a result after the fact.
That last one is the part nearly everyone skips, and it is the reason this page links a ledger rather than a screenshot. A screenshot shows that something appeared on a screen once. It cannot show that the record was not edited afterwards, and a reader cannot recompute it.

The cart is built, the code is entered at the cart stage before any payment step, the discount line is read back, and the cart is cleared. No order is ever submitted and no payment details are entered — which also means this test says nothing about shipping, fulfilment or returns, and we do not claim otherwise.
A code tested repeatedly against the same cart proves only that it works on that cart. A minimum-purchase threshold, a category exclusion or a per-product rule would never be exercised, and so would never show up as a failure. Rotating the product means those rules surface instead of hiding. Across the whole series the baskets have ranged from $40.00 to $1,800.00, covering 90 distinct products, and the rate has held at 10% on every one of them.
That rotation is also why the series is worth more than its length. Counting every code we test and not only this one, 746 code-and-cart reads have been recorded, and 745 of them returned a discount line. HEALTHYLIFE10 itself has returned one on all 126 of its reads. The 1 exception was on September 20, 2026, on one of the secondary codes described further down, and it is stated here for the same reason the passes are: a series containing no failures at all is either very short or has been groomed, and a reader has no way to tell which — which is precisely the problem this page exists to avoid. That day's full record, all codes included, is in the dated entry for it.
Every test is an entry in a chain. Each entry's identifier is a SHA-256 hash of the previous entry's hash joined to that entry's own canonical record. Change any figure in any earlier entry and that entry's hash changes — and so does every hash after it, visibly, to anyone who recomputes the chain.
The current head of the chain is 3707ae606c95ed3499f60e92dde76838…. Every entry
publishes its canonical record and both hashes, so the check needs nothing from us beyond
the page itself: the full ledger, and
the protocol it follows.
Stamping a current date on an unchanged page is trivial, and common enough that a date by itself should not persuade anyone. What distinguishes a page that was actually rechecked is that the figures move with the date, not just the date.
So three things on this page change when the check is rerun, and all three are visible to you. The cart is a different product at a different price each time — today ARA-290 10mg at $50.00 CAD. The chain head above changes, because a new entry has been appended to it. And the entry count advances by one. A page that was restamped rather than rechecked would show a new date against yesterday's cart, yesterday's hash and yesterday's count, which takes about five seconds to notice if you look.
Today's reading was taken at 00:24 ET, and confirmed again at 04:46 ET. Earlier readings are not overwritten when a later one is taken; they are separate entries in the ledger, which is why the count rises faster than the number of days.
Growth Guys applies a further 20% of its own when an order is paid with Bitcoin, with no code involved. Put together with HEALTHYLIFE10 that is 30% off in total — and the arithmetic is the part most listings get wrong, including, for three days in September, ours.
Two percentage reductions do not add. HEALTHYLIFE10 comes off the subtotal first, and the store's 20% then applies to what is left rather than to the original figure. On the cart we read for this: $430.00 CAD subtotal, $43.00 CAD off for the code, $86.00 CAD off for the payment method, $129.00 CAD removed in total, $301.00 CAD to pay. Adding the two percentages instead would imply a larger saving than the store actually gives. Our own correction is logged, dated, on the corrections page.
HEALTHYLIFE10 is not the only code that works at Growth Guys, and it would be convenient to imply it is. It is not. We test 6 codes against live carts every day, each at its own basket value, and every one of them has been read at least 116 times.
All of them return the same 10%. No code we have found returns more than that — no larger coupon, and no first-order code — and we have been looking daily for 40 days. The larger reductions described above come from the store's own sale and its Bitcoin payment discount, neither of which needs a code at all. If a bigger code appears, it will show up in the ledger as a larger discount line on the day it works, before it appears in any sentence we write about it.
This matters because the usual way a coupon page handles a second working code is to present it as an upgrade. The honest version is duller: the codes differ in name and in nothing else, so the one worth using is simply whichever you can remember at the cart, and the figure to check is the discount line, not the code.
A discount is only interesting if the thing being discounted is what it says it is. Growth Guys publishes 244 third-party assay reports through Janoshik Analytical, covering 133 distinct products. Across the 182 that state a purity figure the average is 99.04%.
The number worth reading is not that average. It is that 33 of those results come in below 98%, with the lowest on record at 93.844%, and they are left published. A set showing only strong results has been filtered, and a filtered set tells you about the filter rather than about the products. The whole record, low results included, is at the assay index.
What makes those reports checkable is where they load: each resolves on the testing laboratory's own portal, carrying the lab's reference and naming the client and the batch. A certificate that exists only as a file on a seller's server can be edited by that seller. One that resolves on the laboratory's domain cannot. That distinction, not the purity figure, is the ten-second check worth making.
None of that requires an account, a payment method, or taking this page's word for anything.
Growth Guys promo code. HEALTHYLIFE10 — 10% off sitewide, verified October 11, 2026 at $5.00 CAD off $50.00 CAD.
Growth Guys discount code. The same code. There is no separate "discount" code; the store applies one code at a time and this is the one we test daily.
Growth Guys coupon code. Also the same code, entered in the coupon field at the cart stage. HEALTHYLIFE10 carries no minimum purchase and no product exclusions, including on the highest-priced items.
Every dated test behind those three sentences is published at the evidence index.
244 published lab reports. 133 distinct products covered. 99.03% average purity across the 181 reports that state one, spanning 93.844% to 99.99%. Every one of them is hosted by Janoshik Analytical rather than by the seller, which is what makes the figures checkable instead of quotable. Shipping is domestic Canadian, pricing CAD, and the vendor has answered in public threads since November 2021. Itemised here.
That 15% reduction was applied by the store itself, to a portion of its catalogue, and it expired on October 5, 2026. The affected listings now show their ordinary prices again.
October 11, 2026, no promotion active: HEALTHYLIFE10 reduced a $40.00 CAD cart by $4.00 CAD to $36.00 CAD. 10%, no minimum, no exclusions.
HEALTHYLIFE10 did not come from that promotion, so it did not leave with it. Sale codes have end dates built in; this one has a daily test instead, and every test is published with its date.
