Prices and the discount are both in CAD and shipping is domestic, so the 10% comes off a Canadian subtotal with no conversion step.

Each row: one cart, built October 7, 2026, at a value chosen to differ from the others. A code with an undisclosed floor passes any single-value test, which is why this one varies. No order, no payment details — guest-cart figures only.
Use it at the cart, not at payment: HEALTHYLIFE10 in the discount field, then confirm the new total. It needs no account, works on a guest cart, and applies again on the order after this one.
244 Janoshik reports. 99.03% mean purity across the 181 that state one, from 93.844% at the bottom to 99.99% at the top, over 133 distinct products. Every report resolves on the laboratory's domain, not the seller's. Orders ship from within Canada and are billed in Canadian dollars. The vendor has been answering in public forum threads since November 2021. Every figure above, itemised.
On the Canadian storefront, prices are listed in Canadian dollars and the discount is taken from a Canadian-dollar subtotal. HEALTHYLIFE10 applies 10% off sitewide, so an $80.00 CAD cart pays $72.00 CAD and the $10.00 saved is $10.00, not an amount that becomes something else by the time it reaches a statement.
This sounds obvious and is routinely not the case. Buying in a foreign currency means the headline discount is taken before conversion, and then the whole total passes through an exchange rate and, on most Canadian cards, a foreign-transaction fee of around two and a half percent. A 10% discount applied to a cart that then carries a 2.5% fee is not a 10% saving. Here there is no conversion step for that to happen in.
Growth Guys runs a Canadian store and a separate United States store. The Canadian site detects visitors who appear to be in the US and offers to send them to the other one, noting that it carries the appropriate pricing, payment options and shipping. The Canadian store ships only to addresses within Canada.
A discount code is a property of the store that issued it, so the first diagnostic when a code will not apply is which storefront you are standing on. The currency beside the cart total answers it immediately. This also matters when comparing a price you saw quoted elsewhere — a figure from the US store is not the figure you will pay here, and the gap is not the discount.
Tested on October 17, 2026 at growthguys.com, at several order sizes on purpose: $50.00 CAD paid $45.00, $70.00 paid $63.00, $75.00 paid $67.50, $100.00 paid $90.00, and $280.00 paid $252.00. Every one is exactly 10% off, on Canadian-dollar prices, with no minimum purchase and no product exclusions.
The spread is the point. A discount that narrowed on larger orders, or that excluded higher-priced categories, would be visible across a range from $50 to $280. The cart value is changed between runs specifically so that a rate holding at only one order size cannot pass unnoticed.
Not the percentage — that is the same wherever you are. What changes is everything around it. The order ships domestically by Canada Post rather than crossing a border, so there is no customs entry, no brokerage charge, and no international facility that can hold a parcel indefinitely. Flex Delivery and PO boxes are both supported.
Those are the variables that actually decide whether a cheaper order is a better one. An equivalent price from a seller shipping into Canada carries a different and much wider range of outcomes, and the difference does not appear anywhere on the product page. It appears when the parcel does, or does not.
Enter HEALTHYLIFE10 in the discount field at the cart stage, not at the payment step. The cart recalculates immediately and a discount line appears equal to exactly one tenth of the subtotal. No account is needed — it works on a guest cart — and it is reusable rather than consumed by a first order.
If the line does not appear, work through the short list before concluding the code is dead: confirm you are on the Canadian store, check that no other coupon is already occupying the cart's single discount slot, and retype the code by hand in case a trailing space came along with it when it was copied.
Yes. It was cart-tested on October 17, 2026 and took $8.00 CAD off an $80.00 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 at growthguys.com on the Canadian storefront, with no minimum purchase and no product exclusions, on prices already in Canadian dollars.
Yes. Prices and the discount are both CAD, so there is no conversion step and no foreign-transaction fee eroding the saving, which is what happens when a percentage is taken before a currency conversion.
Most often you are on the US storefront rather than the Canadian one, or another coupon is already on the cart occupying the single discount slot, or a trailing space was copied with the code. Check the currency beside the total first.
