Oath Promo Codes
About This Oath Promo Codes Site
This is a deal site. It exists for one reason: to keep two working promo codes for Oath Research in one place, so you don't have to dig through old forum posts or expired screenshots to find one that still works. That's the entire pitch — no loyalty program, no newsletter, no account required just to look around.
Nobody who runs this site takes a commission, a referral fee, or anything else when you use a code here. That's true today, and if it ever changes, this page will say so plainly instead of staying quiet about it. There's nothing complicated about what this site is or why it exists, and the rest of this page just spells that out in a bit more detail.
What This Site Does
Two things: it keeps the current working Oath Research codes front and center, and it explains enough about Oath — their testing, shipping, and returns — that you can decide whether ordering makes sense for you before you commit to anything. That's the whole job, kept deliberately narrow, and it's not trying to be more than that.
Codes get checked against Oath's checkout before they're posted here, and this page gets updated when a code changes or a new one replaces an old one. When a code stops working, it moves to the expired list rather than just disappearing, so there's a record of what used to apply and when it stopped. Nothing gets deleted quietly, and nothing gets left up just because it's easier than fixing it. If you check this page every few weeks, what you see should always reflect what's actually live at checkout, not what used to be true a month ago.
What It Doesn't Do
This site doesn't sell anything. It doesn't process orders, handle payments, or ship products — all of that happens directly through Oath, on Oath's own site, using Oath's own checkout. It doesn't offer dosing advice, protocols, or guidance on how to use anything Oath sells, because Oath sells research material, not medicine, and neither this site nor Oath gives that kind of guidance to anyone. That's a hard line, not a soft suggestion.
It also doesn't take a commission on the codes it publishes. There's no referral link involved, and no cut taken on anything you order through Oath, now or later. That's not a promotional claim with fine print attached — it's just how this operates. If that ever changes, this page is where it would say so, not somewhere you'd have to go looking for it. That commitment doesn't expire the way a promo code does.
How Often This Page Changes
There's no fixed schedule. This page gets updated whenever a code changes — a new one goes up, an old one stops working, or a discount amount changes from what's listed here. There's no quarterly review, no set day of the month, just whatever the checkout actually says. That's intentional — a fixed schedule would just mean stale information sitting here between updates. Between updates, what's posted here should match what actually works at checkout, and we'd rather correct it fast than leave it wrong.
If something here ever doesn't match what you see at Oath's checkout, trust the checkout. Codes can change faster than any page tracking them can keep up with, and a live checkout is always a more current source than a page updated by hand. That's true here just as much as anywhere else. A promo code page that hasn't been checked recently is worth being skeptical of, and that standard applies to this one too.

Copy either code above, then paste it into the discount field at checkout. The 20% code is for first orders; the 15% code works every time.
