This is the definitive guide to that code — written and maintained by the person the code belongs to. I'm Steven Gawinski, an official Unmatched Supplements ambassador, and STEVEN10 is my personal ambassador code, issued directly by the brand. That matters more than it sounds: most promo code pages on the internet are aggregator sites that scrape codes from Reddit threads and expired email campaigns, list twenty "deals" that mostly don't work, and never test a single one. This page works differently. Every month I run STEVEN10 through a real checkout on unmatchedsupps.com before updating the verification date you see above, so when this page says the code works, that claim is hours-to-weeks old, not years.
Below you'll find everything a careful buyer would want to know before ordering: the exact checkout walkthrough, a full-price-versus-code price table for every product in the lineup, the stacking math that shows how STEVEN10 compounds with sitewide sales (this is where the real savings hide — a 20% sale becomes 28% off with the code on top), how the $150 free-shipping threshold interacts with the discount, and honest answers to the questions people actually ask, including what to do in the rare case the code doesn't apply. If you just want the code and a checkout walkthrough, the short version lives at the quick promo code page. This page is for everything else — bookmark it, because the numbers update as prices and sales change.
Why Trust This Page
I'm Steven Gawinski, an official Unmatched Supplements ambassador. STEVEN10 is my personal ambassador code — I don't scrape codes from Reddit or recycle expired promotions. Before I update the "last verified" date on this page, I run the code through a real checkout on unmatchedsupps.com myself. It was last verified working in July 2026.
One more thing worth being upfront about: I earn a commission when someone orders with STEVEN10. That's how ambassador codes work — you get 10% off, the brand attributes the sale to me. I have no affiliations with any competing supplement brand, so there's no incentive here to steer you anywhere except toward the lowest price on products I actually use.
How to Use STEVEN10 at Checkout
- 1Shop at unmatchedsupps.com and add everything you want to your cart. The code has no minimum, so cart size doesn't matter.
- 2Open your cart and click Checkout.
- 3In the "Discount code or gift card" field, type STEVEN10 — no spaces, capitalization doesn't matter — and click Apply.
- 4You'll see a discount line appear and your total drop by 10%. If a sitewide sale is running, the sale discount and the code discount both show on the order summary. Complete payment as normal.
How Much Can You Save?
Here's the current lineup at full price versus what you pay with STEVEN10 applied:
The 10% is real money on a single order, but the code's actual value shows up when Unmatched runs a sitewide sale, because STEVEN10 stacks on top of the sale price. The math compounds. Using BH2K ($59.99) as the example:
The pattern: a 15% sale becomes 23.5% off, a 20% sale becomes 28% off. Whatever discount the site is running, STEVEN10 adds roughly 8–10 more percentage points on top.
About STEVEN10
STEVEN10 is a permanent ambassador code, which puts it in a different category from the promotional codes most coupon sites list. There's no expiration date and no end-of-campaign cutoff — it works in January and it works on Black Friday. There's no minimum order, so it applies whether you're buying a single Longevity Multi or stocking up for six months. And it stacks with every promotion Unmatched runs, including the biggest sales of the year. If you ever find it not working, the problem is a typo, not the code.
About Unmatched Supplements
Unmatched Supplements was founded by Kris Gethin, who previously co-founded Kaged. After leaving Kaged, Gethin built Unmatched around the standards he's advocated for years: every product is third-party tested, every label is fully disclosed with no proprietary blends, and formulas skip the fillers that pad cheaper products. The lineup covers pre-workout (BH2K), creatine (CreGAAtine), electrolytes and cutting support (ElectraShred), nootropic energy (Outlier), whey isolate, and a longevity-focused multivitamin — all sold directly at unmatchedsupps.com.
That direct-to-consumer model is also why an ambassador code like STEVEN10 exists: instead of paying retailers a margin, the brand routes part of that margin back to customers as a discount through ambassadors.
Frequently Asked Questions
What is the Unmatched Supplements promo code?
The Unmatched Supplements promo code is STEVEN10. It takes 10% off any order at unmatchedsupps.com with no minimum purchase and no excluded products. It's an official ambassador code issued directly by the brand — not a scraped third-party coupon — which is why it works every time it's typed correctly. Enter it in the "Discount code or gift card" field at checkout and the 10% comes off your subtotal immediately.
Does STEVEN10 expire?
No. STEVEN10 is a permanent ambassador code with no expiration date. Unlike promotional codes that end with a campaign, it works every day of the year — in January, in July, and during Black Friday. This page is re-verified with a real checkout each month, and the "last verified" date above only gets updated after the code has actually been confirmed working.
How does the stacking math work with 10%, 20%, and 30% sitewide sales?
The sale discount applies first, then STEVEN10 takes 10% off the already-discounted price. Using BH2K ($59.99) as the example: during a 10% sale, $59.99 drops to $53.99, and STEVEN10 brings it to $48.59 — 19% off sticker. During a 20% sale, $59.99 drops to $47.99, then to $43.19 with the code — a combined 28% off. During a 30% sale, $59.99 drops to $41.99, then to $37.79 — 37% off the original price. The discounts multiply rather than add, which is why 20% + 10% works out to 28% rather than 30%, but the code still shaves real dollars off every sale tier.
Does STEVEN10 work on bundles and multi-buy deals?
Yes. Because STEVEN10 applies to your cart subtotal rather than to individual SKUs, it works on bundle listings and multi-unit purchases the same way it works on single products. If a bundle is already priced below the sum of its parts, the code takes 10% off that bundle price — the discounts layer just like they do with sitewide sales. If a specific bundle ever refused the code at checkout, that would be a store-side configuration issue worth reporting, not a limitation of the code itself; in months of verification checkouts I haven't hit one.
How do I get free shipping at Unmatched Supplements?
Orders of $150 or more ship free from unmatchedsupps.com. Importantly, the threshold is checked against your subtotal after STEVEN10 is applied — so a $160 cart that drops to $144 with the code does not qualify. To clear $150 post-discount, your pre-discount cart needs to be roughly $167 or more. If you're close, adding a smaller item like the Longevity Multi ($39.99) is usually cheaper than paying the shipping fee, and you get a product instead of a receipt line.
Does STEVEN10 work on subscription or recurring orders?
If Unmatched offers a subscribe-and-save option on a product, STEVEN10 applies at checkout the same way it does on a one-time purchase — enter it in the discount field before completing the order. Whether the 10% recurs on every subsequent renewal is controlled by the store's subscription platform, and platforms handle discount persistence differently, so check the order confirmation on your second billing cycle. The dependable pattern: the code always works on the checkout where you enter it, and one-time orders are the guaranteed way to capture the discount every single time.
Does STEVEN10 work on all Unmatched products?
Yes — every product on unmatchedsupps.com, including BH2K, CreGAAtine, ElectraShred, Outlier, Isolate, and the Longevity Multi. There are no brand-imposed exclusions, no category carve-outs, and it works on new releases from the day they launch. Many stores quietly exclude best-sellers or new drops from coupons; Unmatched doesn't, which is part of why an ambassador code here is genuinely worth using rather than a marketing gimmick.
How does STEVEN10 compare to other ambassador and influencer codes?
Structurally it's the same deal you'll find across the supplement industry: most ambassador codes are 10% off, and no legitimate ambassador for the same brand can offer a deeper cut — the brand sets the percentage, not the ambassador. So the deciding factors are reliability and honesty, not the number. What separates STEVEN10 from the average influencer code is verification: many codes floating around social media belong to lapsed ambassadors and silently stopped working months ago. This one is re-tested with a real checkout every month, stacks with every sitewide sale, and has a page that publishes the actual math instead of just shouting a percentage.
What should I do if STEVEN10 stops working at checkout?
Work through it in order. First, check for typos — it's STEVEN10 with no spaces, and capitalization doesn't matter. Second, make sure you're on unmatchedsupps.com itself, not a third-party marketplace listing; ambassador codes only work on the brand's own store. Third, clear any other discount code from the field — checkout accepts one code at a time (sitewide sales stack automatically and don't need a code). If it still won't apply, it's almost certainly a temporary store-side glitch: try again in a few hours, or reach out through this site and I'll re-verify the code personally and get back to you.
What's the connection between Unmatched Supplements and Kris Gethin?
Kris Gethin co-founded Kaged (formerly Kaged Muscle), left the company, and later founded Unmatched Supplements with Doug Miller. Unmatched is his current brand and reflects the approach he's advocated for years: third-party testing, full label transparency, no proprietary blends, and clinical doses of premium ingredients like paraxanthine and DiLeucine instead of cheap fillers.
