Worked examples at five real cart values from actual tests, rather than a percentage with no arithmetic attached.
| 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% |
Built on September 22, 2026, one cart per row, at deliberately different subtotals. The point of moving the value is that a price-capped code would otherwise pass every test. No order was submitted and no card was entered; every number is from the guest cart.
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 arithmetic is simple; what people are really asking is whether the rate holds. It does. These are tested carts, not worked examples:
| Cart | Discount | Paid |
|---|---|---|
| $60.00 CAD | −$6.00 | $54.00 CAD |
| $120.00 CAD | −$12.00 | $108.00 CAD |
| $280.00 CAD | −$28.00 | $252.00 CAD |
| $400.00 CAD | −$40.00 | $360.00 CAD |
Exactly 10% at every value. The useful figure to carry: every $100 of cart is $10 off, and it does not change with spend.
One case where the total is lower still: if an automatic sale is running, that reduction comes off first and HEALTHYLIFE10 then takes 10% off the reduced subtotal. The two compound rather than add.
Yes. The most recent check was October 16, 2026: $5.00 CAD off a $50.00 CAD cart at growthguys.com, a clean 10%. Nothing here is asserted from memory — the figures come out of that day's test.
Every $100 of cart is $10 off. The rate does not change with spend, so the arithmetic holds at any value.
Of the subtotal, applied at the cart stage before checkout.
Yes, when the vendor is running an automatic reduction. That comes off first and the code then takes 10% off the reduced subtotal, so the two compound.

244 third-party reports, published rather than described. They come from Janoshik Analytical, cover 133 products, and open on the laboratory's own domain — the distinction that separates a testing claim from testing evidence. Mean purity across the 181 reports carrying a figure is 99.03%, between 93.844% and 99.99%. Canadian warehouse, Canadian dollars, public vendor threads answered since November 2021. Every report, counted.
