Does Growth Guys only take bitcoin — last verified at checkout at Growth Guys (growthguys.com): October 24, 2026 (today), 01:27 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.
Payment method is a fact about a seller's banking relationships, not about its product. The discount is applied at the cart, before payment is chosen, so the rate is the same whichever route you take.
| Cart subtotal | Discount | Paid | Rate |
|---|---|---|---|
| $40.00 CAD | −$4.00 CAD | $36.00 CAD | 10.0% |
| $175.00 CAD | −$17.50 CAD | $157.50 CAD | 10.0% |
| $50.00 CAD | −$5.00 CAD | $45.00 CAD | 10.0% |
| $40.00 CAD | −$4.00 CAD | $36.00 CAD | 10.0% |
| $100.00 CAD | −$10.00 CAD | $90.00 CAD | 10.0% |
| $150.00 CAD | −$15.00 CAD | $135.00 CAD | 10.0% |
One cart per line, all from October 24, 2026. The subtotals are not the same on purpose — if the code only applied below some threshold, a fixed-value test would never show it. Nothing was bought; the figures are read off the guest cart before checkout.
Add anything to the cart, enter HEALTHYLIFE10 in the discount field at the cart stage, and confirm the discount line changes before you continue. No account and no sign-in are needed; the code applies to a guest cart, and it is reusable, so it behaves the same on a second order as a first.
Not from the vendor's marketing. 244 test reports are published through Janoshik Analytical and each one opens on the lab's own site, which is what separates a testing claim from testing evidence. Across the 181 reports stating a purity figure the mean is 99.03%, the lowest kept on record is 93.844% and the highest 99.99%, spread over 133 products. Canadian stock, Canadian dollars, public vendor threads since 2021. The whole set.
The worry behind it is reversibility. A card payment can usually be disputed through the issuer; a cryptocurrency transfer generally cannot. A buyer asking whether a seller takes only one of those is really asking what recourse exists if the order goes wrong, which is a reasonable thing to want to know before paying.
It is worth separating that from a second, weaker inference people often draw: that a seller accepting cryptocurrency is somehow less legitimate. In this category, payment options are shaped mostly by which processors will underwrite the merchant category at all, and that is a banking decision rather than a statement about the goods.
Payment options change, and they change without announcement. A thread from eight months ago describing what was accepted then is not evidence about today, and this is one of the few questions where the live page answers definitively in under a minute.
Build a cart, proceed to the payment step, and read what is offered. You are not committed to anything by looking: the payment step lists the available methods before any payment details are entered, and the cart can be abandoned at that point with nothing submitted.
HEALTHYLIFE10 is entered in the discount field at the cart stage, and the discount line appears immediately, before a payment method has been selected. That ordering is the practical answer to a question we are asked often: the rate does not depend on how you pay.
So a cart that comes off by ten percent will still be ten percent off whichever of the offered routes you take at the next step. The code works on all orders and carries no product exclusions, and neither of those terms is conditioned on a payment type.
If reversibility matters to you, choose the method that preserves it and accept whatever that costs in convenience. That is a sound way to manage the risk, and it is entirely separate from whether the seller is sound.
If you pay by a method with no chargeback route, the thing that protects you is the record rather than the bank: a batch number on the item that resolves on the testing laboratory's own portal gives you something checkable in your hand. That is a different kind of protection, and for product identity it is the stronger one.
Confirm the discount line reads exactly one tenth of the subtotal before shipping. That line, not the banner, is what tells you the code applied. If it reads anything else, the code did not take and nothing has been lost by finding out at the cart rather than afterwards.
Then confirm the payment step offers a route you are comfortable with. Two minutes spent on those two checks settles both halves of this question with the live site rather than with a guess.
Working as of the October 24, 2026 run: $4.00 CAD off $40.00 CAD, exactly 10%, on a live cart at growthguys.com. If a run ever fails the date here stops moving, which is the point of stamping it.
Not here. HEALTHYLIFE10 is applied at the cart, and the discount line is rendered before payment is selected, so the ten percent is already fixed by the time the payment step is reached.
Acceptance by itself tells you about the seller's processors, not its product. Judge the product on the batch-matched testing record and judge your own exposure on the recourse the method gives you.
The payment step is reached from a guest cart, so the options can be read without an account and without entering any payment details.
