Cart-verified October 11, 2026: 10% off sitewide at Growth Guys (growthguys.com) using HEALTHYLIFE10 — no minimum purchase and no product exclusions — with a $100.00 CAD cart settling at $90.00 CAD.
The 10% comes off your whole subtotal, and semaglutide orders are rarely one item — most carts pair the vial with bacteriostatic water and supplies. Because the discount is subtotal-wide, the saving scales with the order, not the single product:
| Claim | Reality |
|---|---|
| "20-30% off semaglutide" on coupon sites | Aggregator-generated; no issuer, no date, fails at checkout |
| "Semaglutide-exclusive code" | Doesn't exist — all Growth Guys codes are sitewide flat 10% |
| "Stack two codes for more off" | Checkout accepts one code per order |
Here's what most people get wrong shopping semaglutide by discount: the codes are identical at 10%, so the real differences between vendors are testing and shipping, not the coupon.
Before ordering semaglutide from any research vendor, confirm two things. First, the batch you'd receive has a current third-party certificate of analysis — Growth Guys publishes Janoshik Analytical reports per batch, and the batch number on the COA should match your vial (our batch-matching guide shows how). Second, that it ships domestically — a Canadian order avoids the customs delays that overseas "bargains" risk. Run any store through the vendor-vetting quiz before comparing prices.

5 of the 244 Janoshik reports on the vendor's lab page cover semaglutide, across 3 distinct product listings. 5 of them state a purity figure; those average 99.43%, from 99.33% at the lowest to 99.64% at the highest. That sits above the 99.03% average across all 244 reports the vendor publishes. Each row opens on the testing laboratory's own portal rather than a PDF hosted by the seller, which is the difference between a testing claim and testing evidence.
| Product | Batch | Purity | Mass | Tested | Lab record |
|---|---|---|---|---|---|
| Semaglutide 5mg | SG05 | 99.39% | 5.03 mg | — | report |
| Semaglutide 10mg | SG04 | 99.64% | 10.85 mg | — | report |
| Semaglutide | SG03 | 99.42% | 5.2 mg | — | report |
| Semaglutide | SG02 | 99.39% | 5.76 mg | — | report |
| Semaglutide | SG01 | 99.33% | 5.30 mg | — | report |
This table is rebuilt from the vendor's published lab page on every run, so a report added or withdrawn appears here rather than being frozen at the date this page was written. Figures are analytical results only — purity, mass, batch and test date. All 244 reports, every compound.
Not from the vendor's marketing. 244 test reports are published through Janoshik Analytical and each one opens on the lab's own site, which is what separates a testing claim from testing evidence. Across the 181 reports stating a purity figure the mean is 99.03%, the lowest kept on record is 93.844% and the highest 99.99%, spread over 133 products. Canadian stock, Canadian dollars, public vendor threads since 2021. The whole set.
