Did the domain change break affiliate or referral links?

No. The old address forwards to the new one and carries the rest of the link with it, including referral and affiliate tags. This was tested directly on 28 July 2026. It is still worth updating saved links, since redirects are usually retired a year or two after a move.

Why won't my discount code apply at checkout?

It is almost never the domain. The common causes are that the item is excluded from the promotion, a cart minimum was not met, a trailing space was pasted along with the code, or the promotion has ended. Check the order summary to confirm the discount appears before paying.

How do I use the code on the new address?

Go to growthguys.com, add items to your cart, and enter HEALTHYLIFE10 in the discount field at checkout. Confirm the 10% reduction appears in the order summary before completing payment — the on-screen confirmation is the only reliable proof on any store.

Does HEALTHYLIFE10 Still Work on growthguys.com? What the Domain Change Did and Didn't Affect

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.

We are an affiliate: if you order from Growth Guys using this code we earn a commission, at no extra cost to you. We are not Growth Guys and have no ownership of or role in the company.

Checked on October 10, 2026 at a live cart: HEALTHYLIFE10 took 10% off sitewide at Growth Guys (growthguys.com) — a $100.00 CAD cart paid $90.00 CAD, with no minimum purchase and no product exclusions.

Does HEALTHYLIFE10 still work now that Growth Guys is on growthguys.com? Yes. The code still takes 10% off at checkout on the new domain (verified October 11, 2026). A discount code lives in the store's checkout system, not in the web address, so moving from growthguys.is to growthguys.com left every code untouched.

Why a domain change doesn't touch a discount code

This trips people up, so it is worth explaining properly. When you enter a code at checkout, the store looks it up in its own database of promotions. That database belongs to the business, not to the domain name pointing at it. Changing the address is closer to a company changing its street sign than to opening a different company — the shelves, the till and the promotions all carry over.

The same logic covers referral and affiliate links. We tested an affiliate-tagged link on the old address on 28 July 2026 and the forward carried the tag through to the new domain intact.

What the move did and didn't affect

Item	Affected by the domain change?
HEALTHYLIFE10 discount code	No — applies at checkout as before
Saved product links	No — the old address forwards and keeps the full link
Referral and affiliate tags on a link	No — carried through the forward
Your bookmarks	Working today, but worth re-saving before the forward is retired
Published lab results	No — same catalogue, same published batch results

If the code doesn't apply, it isn't the domain

When a code fails at checkout, people reach for the most recent change they can remember and blame it. Since the address change is the visible recent event, it gets the blame. It is almost never the cause. The usual reasons a code will not apply are far more boring:

The item is excluded. Sale items and some bundles are commonly carved out of discount promotions.
A minimum was not met. Some promotions attach a cart minimum.
Formatting. A trailing space pasted along with the code is the single most common cause.
The promotion ended. Codes are dated, which is why the ones you find on aggregator sites are so often dead.

Our view on why so many listed codes fail in the first place is set out in our check on whether HEALTHYLIFE10 is a valid code.

How to use it on the new address

Go to growthguys.com, add what you want to the cart, and enter HEALTHYLIFE10 in the discount field at checkout. Confirm the 10% actually appears in the order summary before you pay — that on-screen confirmation is the only proof that counts, on any store.

One practical note for late July 2026: the store is currently showing a notice that credit and debit checkout is temporarily affected, with a stated expectation of being resolved by August. If a card is how you prefer to pay because it may give you a dispute path, waiting is a reasonable call. A temporary outage is never a good reason to rush into a payment method you cannot walk back.

The bottom line

HEALTHYLIFE10 = 10% off, working on growthguys.com (verified October 11, 2026).
The domain change affected nothing about codes, links or the catalogue.
A failed code is almost always an exclusion, a minimum, or a pasted space.
Confirm the discount on screen before paying.

What can be checked about this vendor

Three things, none of which require trusting anyone. The testing: 244 reports covering 133 products, each hosted on the lab's own domain rather than the seller's, averaging 99.03% and ranging 93.844% to 99.99%. The logistics: orders leave from inside Canada and are priced in Canadian dollars, so there is no customs step and no conversion. The history: public vendor threads answerable since 2021. We counted every report, weaker results included.
