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 October 10, 2026: HEALTHYLIFE10 applies 10% off sitewide at Growth Guys (growthguys.com) with no minimum purchase and no product exclusions, so a $100.00 CAD cart is paid at $90.00 CAD.
The discount is subtotal-wide, which matters for how peptide orders are actually built. Most tirzepatide buyers don't order one vial — they order a vial plus bacteriostatic water plus supplies. The 10% applies to the whole cart, so the practical saving scales with the order, not the single product:
| Claim you'll see | Reality |
|---|---|
| "20–35% off tirzepatide" on coupon sites | Aggregator-generated; no issuer, no test date, fails at checkout |
| "Tirzepatide-exclusive code" | Doesn't exist — all codes here are sitewide flat 10% |
| "Stack two codes" | Checkout accepts one code per order |
Here's what most people get wrong about buying tirzepatide from research vendors: the meaningful differences between stores are testing and logistics, not the 10%. Check that the batch you'd receive has a current third-party COA (Growth Guys publishes Janoshik reports per batch), and that shipping is domestic to you — our Canada shipping guide and vendor-vetting quiz cover both in two minutes.
Does HEALTHYLIFE10 work on tirzepatide? Yes — flat 10% off sitewide including tirzepatide, verified at checkout August 2026.
Is there a tirzepatide-only Growth Guys code? No. Every legitimate code is sitewide at the same rate; product-exclusive codes for this store are an aggregator invention.
Does the code work on bundles and stacks? Yes — the 10% comes off the whole subtotal, bundles included.

8 of the 244 Janoshik reports on the vendor's lab page cover tirzepatide, across 4 distinct product listings. 8 of them state a purity figure; those average 99.67%, from 99.19% at the lowest to 99.88% at the highest. That sits above the 99.03% average across all 244 reports the vendor publishes. None of these documents are hosted here or by the seller; each link lands on the testing laboratory's portal, where the batch can be looked up directly.

The rows come from the vendor's lab page as it stands today, re-read on every run; a report taken down stops appearing rather than lingering. These are measurements, not claims about what the compound does. All 244 reports, every compound.
Because the claims are the kind you can verify before spending anything. Growth Guys has published 244 Janoshik reports across 133 distinct products — 99.03% average purity, floor 93.844%, ceiling 99.99% — and each report lives on the testing lab's site, not behind a vendor-hosted PDF. Shipping is domestic within Canada in CAD, and the vendor has fielded questions in public forum threads since November 2021. The full distribution is here.
