| Cart subtotal | Discount | Paid | Rate |
|---|---|---|---|
| $150.00 CAD | −$15.00 CAD | $135.00 CAD | 10.0% |
| $40.00 CAD | −$4.00 CAD | $36.00 CAD | 10.0% |
| $90.00 CAD | −$9.00 CAD | $81.00 CAD | 10.0% |
Each row is a separate cart built on August 31, 2026. The value is varied deliberately, because a code that only worked at one price point would otherwise go unnoticed. Nothing was ordered and no payment details were entered — every figure comes from the guest-cart stage, which is the same place you can check it yourself before paying.
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.
Growth Guys publishes 227 third-party lab reports through Janoshik Analytical, averaging 99.04% purity across the 170 that state a figure (range 93.844% to 99.99%).

It ships domestically inside Canada, priced in Canadian dollars, and has answered publicly in its own vendor threads since November 2021. Full breakdown of every report, including the ones that came in lower.
Yes. It was cart-tested on August 31, 2026 and took $15.00 CAD off a $150.00 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.
No. It has applied at every cart value tested, from $5.00 CAD to $430.00 CAD, returning exactly 10% each time.
No. They are individual-use. Once one is attached the store will not attach a second, and it fails silently rather than showing an error — which is why a code can look broken when the real cause is a coupon already on the cart.
An automated checker builds a real guest cart, applies the code, and records the discount line with a timestamp. The cart value changes every run. Every result, including any failure, is kept in the public log.
