A real question with no page answering it. Every existing page assumes a Canadian buyer. Answers the shipping-origin question directly and explains that the customs advantage we cite is specifically a domestic-Canada advantage, which no competing page distinguishes.

Every row above is its own cart, built on October 6, 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 in the discount box on the cart page and check that the total moves before going any further. It works on a guest cart with no sign-in, and it is not a single-use code, so the same entry works on every later order.
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.
Orders placed on the Canadian storefront can only be shipped to addresses within Canada. That is stated plainly by the store itself, and it is not a soft restriction that a US address might slip through — the destination is the constraint.
There is, however, a separate Growth Guys US storefront. The Canadian site detects visitors who appear to be in the United States and offers to redirect them, noting that the other store carries the appropriate pricing, payment options and shipping. So the answer to whether Growth Guys ships to the USA is yes, but not from this store.
Shipping research compounds across an international border introduces a customs entry, and a customs entry introduces an authority that can inspect, delay, assess duty on, or refuse a parcel. A domestic network has none of those decision points. Running two domestic operations removes the border from every order rather than managing it on each one.
That is why the split is a feature rather than an inconvenience, and it is the same reason a Canadian buyer should prefer the Canadian store over any seller shipping in. The relevant cost is not postage; it is the probability that a parcel is held somewhere you cannot reach it.
Prices on the Canadian store are in Canadian dollars. A figure quoted from the US store is in a different currency and is not comparable without conversion — and the gap between them is not a discount, which is a common misreading when someone lands on the wrong storefront after a search.
A discount code is likewise a property of the store that issued it. HEALTHYLIFE10 is the Canadian-store code and applies 10% off sitewide there with no minimum and no product exclusions. If a code appears to fail, the first diagnostic is which storefront you are standing on; the currency beside the cart total answers it immediately.
This is the comparison most people are actually making, and the headline price is the least informative part of it. An inbound international parcel can attract a brokerage charge, a duty assessment, and a delay measured in weeks rather than days — none of which appears on the product page, and all of which are conditional, so they do not show up in an average either.
Against that, the Canadian store ships domestically by Canada Post with tracking on every order, free above $350.00 CAD, with Flex Delivery and PO boxes supported, and a stated delivery estimate of one to two business days after a same-business-day dispatch. The narrower range of outcomes is the thing being bought.
The testing record is a property of the products rather than the storefront: reports are published through Janoshik Analytical and resolve on the laboratory's own portal under its own reference, so a batch code can be checked the same way whichever side of the border it was bought on.
Pricing, payment options, shipping rules and discount codes do not transfer. Treat them as two separate shops that happen to share a brand and a supply of documentation. Confirm which one you are on before comparing anything, and do not carry a code or a quoted price across.
Yes — the October 10, 2026 test applied it to a $100.00 CAD cart and took $10.00 CAD off, which is exactly 10%. The date on this page moves only when a test passes, so it records the last confirmation rather than the day the page was written.
Not from the Canadian store, which ships only to addresses within Canada. There is a separate Growth Guys US storefront, and the Canadian site offers to redirect visitors who appear to be in the United States.
No. A discount code belongs to the store that issued it. HEALTHYLIFE10 is the Canadian-store code, applying 10% off sitewide there with no minimum and no product exclusions.
An international parcel means a customs entry, which introduces inspection, delay, duty and brokerage as possible outcomes. Two domestic operations remove the border from every order instead of managing it on each one.
