Oath Discounts
Oath discount code FAQ
Straight answers to the questions that come up most about the two Oath Research codes on this page, the free-shipping line, and Oath itself — no code strings written out here, since checkout is where those actually belong, but everything about how the codes behave, who they're for, and what Oath backs them with is covered below. If a question you have isn't answered here, the how-to-use and why-oath pages go into more depth on the mechanics and the testing record, respectively. Every dollar figure below is calculated from Oath's own published prices, the same way it is everywhere else on this page — nothing here is rounded for convenience or estimated, and nothing is a guess about how Oath's checkout will behave on a specific order.
Do the two Oath discount codes stack?
No — Oath's checkout takes one code per order, and combining the two hasn't been tested, so this page doesn't assume or claim they work together. If you happen to qualify for both, which is true on a genuinely first-time order, apply whichever one gives you the bigger discount for that basket rather than trying to enter both. In most cases that's the new-customer code, since it's the larger of the two — but only on a first order, since it stops applying after that. On every order after your first, the everyday code is the one to use, and it's the only one of the two you'll need going forward.
Why did the new-customer code get rejected on my order?
That code is built to apply once, to a first Oath order — that's the only condition tied to it, and it's not a glitch when it gets rejected on a later order. If you've placed an order with Oath before, under any account, the code won't go through, and that's expected behavior rather than a checkout error. The fix is straightforward: use the second code on this page instead. It has no first-order requirement and no published minimum, so it works on any order, first or fifteenth. It's a smaller discount than the new-customer code, but unlike that one, it doesn't stop working after your first purchase.
Is there a minimum order size for either code?
The everyday code has no minimum — Oath states that plainly, and it applies the same way whether your cart holds one item or ten. The new-customer code doesn't have a published minimum either, but it does have its own condition: it only works on a first Oath order, regardless of order size. So neither code requires you to hit a specific dollar amount before it applies. The $250 free-shipping line is a separate, unrelated threshold — it's based on order value and has nothing to do with either code's eligibility.
What's the difference between the new-customer code and Oath's own 15% new-account offer?
These are two different things that happen to both involve new accounts, which makes them easy to mix up. Oath's own site already advertises 15% off to new accounts as a standing offer. The new-customer code on this page is separate from that, and it's bigger: 20% off a first order instead of 15%. On a $100.00 order, that's the difference between $85.00 with Oath's own offer and $80.00 with the code here — five real dollars more in savings, on the same order, for using this code instead of the default.
Does this site get paid when I use a code?
No. There's no commission, no affiliate payment, and no cut of any kind on either code — using one costs this page nothing to lose and earns it nothing to gain. That's worth stating plainly rather than leaving it implied: nobody connected to this page is paid by Oath Research, and the codes here work exactly the same whether or not anyone ever uses them from this page specifically. The only thing this page does is show Oath's own live prices and codes with the arithmetic already done.
What should I do if a code says it's invalid at checkout?
Start with the basics: check for a typo or an extra space, and copy-paste the code rather than retyping it if you can. Next, make sure you're using the right code for your situation — the new-customer code only works on a first Oath order, so it will be rejected, correctly, on any order after that. Also confirm you're not trying to enter a second code on top of a first one; Oath's checkout accepts one code per order. If none of that explains it, try the other code on this page — between the two of them, one should apply to almost any order.
Will these codes keep working?
Not indefinitely — codes change, and there's no way to guarantee either one stays active forever. That's exactly why this page exists in its current form rather than as a one-time post: it gets rechecked, and anything that stops applying moves to the expired-codes list rather than staying up as if it still worked. If you're reading this and a code doesn't go through, the expired page is the place to check next, and the home page reflects whatever is currently live.
How much does free shipping actually save me?
Oath doesn't publish a flat shipping cost for orders under $250, so this page can't put a specific dollar figure on what you avoid paying — only that clearing the $250 line removes a shipping charge from your order entirely rather than reducing it. What can be priced out exactly is how close a given basket sits to that line: four items like a BPC-157, a GHK-Cu, an Ipamorelin, and a CJC-1295 total $205.00, which is $45.00 short of $250.00. Adding one more mid-priced item is usually enough to clear it.
How fast does Oath actually ship, and is 2-day delivery guaranteed?
Most orders ship by 2-day business air, typically UPS, and orders placed before 12:00 p.m. MST on a weekday go out that same day. What Oath guarantees is dispatch on that schedule — getting the package to the carrier on time — not a specific delivery date once it's in transit. That's a meaningful distinction: "2-day air" describes the shipping method, and the actual arrival depends on the carrier from that point forward. Real-time tracking is provided on every shipment, so you're not left guessing once it's on its way. Oath currently ships within the United States only.
What happens if my order arrives damaged or wrong?
Oath refunds or replaces orders that arrive damaged in transit, as long as photos are submitted within 48 hours, and the same applies if the wrong item shipped, if tracking shows delivered but nothing arrived, or if a batch doesn't meet its own stated specifications or purity. There's no restocking fee on an approved return. Oath responds to a return request within 24 to 48 hours, and an approved refund processes in 5 to 7 business days. The purity clause is the strongest part of this policy — it means the certificate of analysis on a batch isn't just a number, it's backed by an actual remedy if the batch doesn't meet it.
Can I return a peptide if I just change my mind?
No — a change of mind isn't covered under Oath's return policy, and neither is opened or used product, improper storage after delivery, or a cancellation requested after an order has already shipped. Returns are reserved for specific issues: transit damage, a wrong item, non-delivery despite tracking showing delivered, a batch that doesn't meet its stated purity, or a duplicate order caught before it ships. That's a fairly standard policy shape for research material once a seal is broken, rather than something unusual to Oath specifically. Worth checking your order before it ships if there's any doubt.
Is there an actual phone number for Oath, or just a contact form?
Both, but they're not equivalent. Oath publishes a real US phone number, +1 480-999-1097, along with a street address in Gilbert, Arizona — and that contact information is corroborated independently across multiple business directories, not just listed on Oath's own site. The contact form on Oath's website requires creating an account before you can submit a message; the phone number doesn't require anything beyond dialing it. Oath's support hours aren't stated consistently across its own pages, so the safe description is staffed weekday hours rather than a specific window. Whether a call gets answered on any given attempt isn't something this page can verify.
Questions about the codes
Most of what comes up about the two codes on this page falls into a few categories: whether they combine, why one of them stops working after a first order, and whether there's a minimum order size tied to either one. The short version, covered in more depth below: no, don't try to stack them; the new-customer code is genuinely first-order-only, not a bug; and neither code has a published minimum, though the new-customer code has its own first-order condition instead of one.
If you're trying to figure out which code applies to your specific situation before you get to checkout, the how-to-use page walks through it step by step with a full worked example, start to finish. This page is faster if you already know roughly what you're asking and just want a direct answer without the walkthrough. Either page draws on the same underlying facts, so there's no risk of getting a different answer depending on which one you check — they're just organized differently for different reading styles.
Questions about shipping, returns, and Oath itself
Beyond the codes, the questions that come up most are about the $250 free-shipping line, how fast orders actually ship, and what happens if something arrives wrong. All three have specific, checkable answers from Oath's own published policies — none of it is a guess or a general industry norm applied to Oath by assumption, and none of it is estimated for convenience.
The why-oath and shipping pages go into more detail on the testing record and the return policy specifically, including the purity guarantee that backs Oath's certificate archive and the exact dispatch cutoff Oath commits to. This page keeps the answers shorter and more direct, for anyone who wants the specific fact without the fuller context and explanation around it. Both pages pull from the same source material, too — Oath's own published shipping, returns, and testing policies — so there's nothing on the longer pages that contradicts what's summarized here, just more detail behind each point.
If your question isn't here
This list covers what comes up most, not everything. If something about a specific order — a shipment, a charge, a product question — isn't answered by anything on this page, that's a question for Oath directly, not for a deal page with no visibility into your order or your account. The contact page has Oath's real phone number and address for exactly that kind of question.
If it's a question about the codes or the math on this page specifically, and it's not covered here or on the how-to-use page, there's a reasonable chance it's simply not something that's been published anywhere yet — this page doesn't guess at conditions that haven't been stated, and it won't invent an answer just to have one on file. That's a deliberate limit, not an oversight: a wrong answer confidently stated is worse than no answer at all, especially on a page whose whole premise is that the numbers on it can be checked and trusted.
