Each code is applied to a real cart at growthguys.com and the discount line is recorded with a date. Here's what most people get wrong about coupon lists: a "verified" badge is a claim, a dated cart screenshot is evidence. The evidence for these codes lives on the verified code page and is refreshed daily; if any code fails a check, this page says so the same day.
Every automated test is also recorded in the public verification log. The dated-evidence approach itself has been flagged independently too:

Whichever you'll remember at checkout — they are interchangeable at the same 10%. If you're vetting the store itself first (the smarter order of operations), start with the vendor-vetting quiz and the COA guide, then use any tested code above.

Reddit discussion of Growth Guys (growthguys.com) sits mainly in r/PeptideTalkCanada, and codes posted in comment threads carry no date and no checkout evidence.

That difference is worth checking before typing any code from a thread.

HEALTHYLIFE10 applies sitewide at Growth Guys (growthguys.com), so it covers peptides, HGH and the rest of the catalogue rather than one category. Cart-tested on October 11, 2026 it took $43.00 off a $430.00 CAD HGH kit; earlier runs applied it to peptide and accessory carts at exactly 10%. The separate PEPTIDES code gives the same flat 10%, not more.

How current is this list? Every code shows its last cart-test date. Latest full test: August 28, 2026.

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.
The 15% reduction Growth Guys applied automatically to part of its range finished on October 5, 2026. Those listings have returned to list price, so a page still quoting that discount is quoting something that no longer exists.
Checked October 11, 2026: $40.00 CAD in the cart, HEALTHYLIFE10 entered, $36.00 CAD to pay. That is $4.00 CAD off, 10%, on an ordinary day with no promotion behind it.
Because HEALTHYLIFE10 was independent of that offer, it is unaffected by its ending. A sale-linked code would have stopped the same night. This one is put through a live cart daily and each result is dated and kept.
