Every November, aggregator pages sprout "Growth Guys Black Friday: up to 40% off" listings. Here's what most people get wrong: those pages are written in advance by template, not sourced from the store. What's actually verifiable today:
| Claim | Status |
|---|---|
| Year-round 10% via HEALTHYLIFE10 | ✅ Verified at checkout daily (latest: August 26, 2026, $9.00 off $90.00 CAD) |
| "Up to 40% off Black Friday" aggregator listings | ❌ No issuer, no history, written by template |
| Product-level sale pricing in November | Unknown until it happens — check the store directly |
Every claim here is dated. The code's current proof lives on the verified code page (daily checkout screenshot), and if Growth Guys announces an actual November promotion, this page will say so with a date — not a template guess. Vetting the store itself? Start with the vendor-vetting quiz.
Does Growth Guys have a Black Friday code? Check the store's own announcements in November. The working year-round code is HEALTHYLIFE10 at a flat 10%.
Can I stack a Black Friday code with HEALTHYLIFE10? No — checkout accepts one code per order. A code can apply on top of sale prices, but not on top of another code.
When will this page update for November 2026? As soon as anything verifiable appears; every update carries a date.
