Where is Growth Guys located — last verified at checkout at Growth Guys (growthguys.com): October 22, 2026 (today), 01:37 ET — HEALTHYLIFE10 applied and working, taking $20.00 CAD off a $200.00 CAD cart, exactly 10% off sitewide, with no minimum purchase and no product exclusions; 2 live-cart checks so far today.
Orders leave from inside Canada and ship domestically, so there is no customs step — which is the actual reason the question gets asked.
| Cart subtotal | Discount | Paid | Rate |

Every one of these was built fresh on October 22, 2026 at a different subtotal. A test that never changes its cart value cannot detect a threshold, so this one changes it. No purchase was completed and no payment details were entered at any point.
Apply it before checkout: HEALTHYLIFE10 in the cart's discount field, confirm the new total, continue. A guest cart is enough — no sign-in, no account, and it stays valid for repeat orders rather than expiring after the first.
The report count: 244, through Janoshik Analytical, spanning 133 products. The purity: 99.03% mean over the 181 reports that state one, floor 93.844%, ceiling 99.99%. The hosting: each report resolves on the lab's domain, not on a PDF the seller controls. The shipping: inside Canada, billed in Canadian dollars. The history: public forum threads since 2021.

Growth Guys Canada operates as a Canadian storefront and ships domestically within Canada by Canada Post. For a buyer, that is the operative fact: the parcel originates and terminates inside the country, so there is no customs entry, no brokerage charge, and no international facility in the chain that can hold a shipment indefinitely.
Most people asking where a vendor is located are not asking for a street address. They are asking which border the parcel crosses, because that determines both the delivery window and the probability of the shipment going sideways. For orders placed on the Canadian store, the answer is none.
There is a separate Growth Guys US store alongside the Canadian one, and 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. The Canadian store itself ships only to addresses within Canada.
This matters if you are shopping across the border, or through a VPN, or are simply in the wrong tab. Prices are quoted in Canadian dollars on the Canadian store, and a discount code is a property of the store it was issued for. Confirm which storefront you are on before you compare a price or test a code against something you read elsewhere.
Contact is by email, with a contact form on the site. The contact page does not publish a street address or a telephone number, which is ordinary for an online-only operation in this category and should be weighed as exactly that rather than as either reassurance or alarm.
A fair way to judge it: a published address that nobody verifies proves very little, while a published laboratory report that resolves on the laboratory's own domain proves something specific and checkable. Judge the operation on the claims you can independently test, not on the presence of a line of text on a contact page.
Two things are, without taking anyone's word for it. The testing is attributed to Janoshik Analytical and the individual reports resolve on the laboratory's own domain under its own reference, so a report can be confirmed without going through the seller's copy of it. And the shipping claim is self-verifying on the first order: a domestic Canada Post tracking number either exists or it does not.
Both of those are stronger evidence about who you are dealing with than a geographic answer would be. The question behind "where are they located" is usually "can I rely on this", and these are the parts of that question that have answers you can check yourself.
Shipping inside the country removes the most common way an order fails, which makes it tempting to treat it as a general reassurance. It is not one. A domestic parcel arriving quickly tells you the logistics work; it says nothing about what is in the vial, and the two questions have entirely separate evidence.
The evidence for the second question is the batch report, and it is worth pulling before the parcel arrives rather than after. Match the code on the vial to a report that opens on the testing laboratory's own domain. This matters more here than at a vendor with a returns policy, because all sales are final — there is no mechanism that unwinds a purchase after the fact, so the checking has to happen on the front end where it can still change a decision.
There is a second thing a location answer cannot give you, and it is often the one people are reaching for: standing in a dispute. Where a seller operates determines which consumer protections nominally apply, but an all-sales-final policy on research compounds narrows that to very little in practice, whatever the province on the invoice. The realistic protection is the checking done before paying, not the forum theoretically available afterwards.
Yes — the October 22, 2026 test applied it to a $80.00 CAD cart and took $8.00 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.
It operates as a Canadian storefront shipping domestically within Canada via Canada Post. There is also a separate Growth Guys US store. The contact page lists email contact rather than a street address or phone number.
No. The Canadian store ships only to addresses within Canada. A separate US storefront exists, and the Canadian site offers to redirect visitors who appear to be in the United States.
By email, or the contact form on the site. No telephone number is published, which is typical for an online-only operation of this kind.
