Oath Peptides Promo Codes
Oath Peptides Promo Codes FAQ
The questions below come up constantly for anyone who remembers the Oath Peptides name and is trying to figure out what happened to it — is the company still around, does the address still work, do old codes still apply. Short answers: yes, it's still operating, just under the name Oath Research now, and the two current promo codes are checked against the live checkout, not carried over from an old list. If your specific question isn't answered here, the how-to-use page covers checkout mechanics in more depth, and the why-oath page covers the testing and shipping details behind the company itself. Everything below is written to be read on its own, without needing the rest of the site for context.
Is Oath Peptides still in business?
Yes. Oath Peptides didn't close — it renamed. The company now operates as Oath Research, and its own site says so directly: the banner across the top reads "Oath Peptides Is Now Oath Research!" The same operation is behind both names. The mailing address, 51 West Vaughn Avenue Suite 205 in Gilbert, Arizona, is unchanged, and so is the published phone number, (480) 999-1097. If you placed an order under the Oath Peptides name in the past, you were ordering from the same business that's now called Oath Research. Nothing about the rename indicates the company stopped operating; if anything, an active rebrand with a live checkout and a growing batch-testing archive points to a business that's operating, not one that's winding down.
Is oathpeptides.com down?
It appears to be. The domain oathpeptides.com looks to be offline or inactive at this point, which lines up with the company's rename to Oath Research and its consolidation onto oathresearch.com. That's a normal step after a rebrand — old domains often get retired once traffic and orders move to the new one. It isn't a sign of the business shutting down; the current site, oathresearch.com, is live, taking orders, and running the same testing and shipping programs described throughout this site. If you have an old oathpeptides.com link bookmarked or saved somewhere, replace it with oathresearch.com going forward.
Do old Oath Peptides promo codes still work?
Most of them don't. Codes that circulated under the Oath Peptides name — shared on forums, saved in old bookmarks, or listed on coupon pages nobody's updated in months — have largely expired, the same way promo codes do at any retailer. The expired-codes page on this site lists specific old codes and roughly when each one stopped working, so you're not stuck guessing. If you want a code that's actually active right now, the homepage tracks two, checked directly against Oath's live checkout rather than pulled from an old, unmaintained list. If a code you're holding isn't on either list, the fastest way to know for certain is to try it at checkout — Oath's cart will reject it immediately if it's dead.
Is Oath Research the same company as Oath Peptides?
Yes. This isn't a case of one company buying another, or a new business borrowing a similar name — it's the same operation under a new name. The clearest evidence is on Oath's own site: the header banner announces the Oath Research name, while the footer copyright line still reads "© 2026 Oath Peptides," which is exactly what you'd expect mid-rename, not something a genuinely separate company would carry over by accident. The physical address and phone number are unchanged across both names. We don't know the business reason behind the rename, and we're not going to speculate — but the identity of the company behind it hasn't changed.
Is it the same testing lab?
Nothing in Oath's public materials indicates a change in testing partner. Certificates published under the Oath Research name continue to name Freedom Diagnostics as the independent third-party lab, using the same methods — HPLC-UV for purity, LC-MS for identity confirmation — that the testing program has used throughout. The rename affected the storefront name, not the testing infrastructure behind it. As of August 2026, the archive covers more than 425 batches, averaging 99.63% purity over the trailing twelve months, searchable at oathresearch.com/lab-results. Roughly 250 of those 425 certificates can be searched without an account; the rest require logging in.
Why does the Oath website still say "Oath Peptides" in some places?
Because the rename is recent and not every page has been updated to match. The clearest example is the site's own footer, which still reads "© 2026 Oath Peptides" even while the header banner announces the Oath Research name. That kind of mismatch is normal in the middle of a rebrand — legal and copyright text often lags behind the more visible parts of a site redesign. It's not evidence of two different companies or a hastily assembled imitation site; it's a company mid-transition. Treat "Oath Peptides" and "Oath Research" as two names for the same current business rather than as a discrepancy to worry about.
Where do I actually go to order?
oathresearch.com. That's the live, current storefront, regardless of which name — Oath Peptides or Oath Research — brought you to this page. The old oathpeptides.com address appears to be offline, so if that's what you had bookmarked, update it. Everything referenced on this site, including both active promo codes, applies at checkout on oathresearch.com. There's no separate site or checkout tied to the Oath Peptides name that you need to track down; it's the same cart, the same account system, and the same testing and shipping programs, just under the current domain.
Does this site earn anything from the promo codes it lists?
No. Neither active code pays this site a commission, a referral fee, or any share of your order — there's no financial arrangement of any kind attached to either code. They're listed here because keeping one page current is more useful than leaving people to dig through outdated forum posts and screenshots for a code that might already be dead. If that ever changes, this page will say so plainly rather than let a claim like that go unstated. What you see in the code module is the whole arrangement: a working code, what it takes off, and nothing else attached to it.
Can I combine both active codes on one order?
No. Oath's checkout accepts one coupon code per order, so the two active codes can't be applied together or stacked. Pick whichever one fits your situation: the first-order code offers the larger discount but only applies to a first order, while the second code has no such restriction and works on repeat orders with no minimum cart size. If you're a returning customer, the first-order code will be rejected regardless of what else is in your cart — that's expected, not a bug, and the second code is the one to use instead.
What if a code I found isn't listed as either active or expired here?
Then it's unverified, and the most reliable way to check it is to try it directly at checkout on oathresearch.com. Add an item to your cart, enter the code in the coupon field, and Oath's own system will tell you immediately whether it's accepted — the order total updates the moment a valid code applies, and a rejected code is reported right away rather than silently ignored. This site actively tracks two codes and checks them against the live checkout, plus a specific list of confirmed-dead codes on the expired-codes page; it doesn't attempt to track every code that's ever circulated online, since most of that list can't be verified either way.
What happens if my order doesn't meet the purity Oath advertises?
It qualifies for a refund or a replacement. Oath's return policy specifically covers product that doesn't meet its stated specifications or purity, in addition to shipping damage documented within 48 hours, a wrong item, non-delivery despite tracking, and duplicate orders caught before shipment. There's no restocking fee, and approved refunds process in 5 to 7 business days, with an initial response typically within 24 to 48 hours. Opened or used product outside of those categories isn't eligible for return, which is standard for research material once a package has been opened.
What payment methods does Oath accept?
Oath's checkout accepts Visa, Discover, and American Express, plus direct bank payment for anyone who'd rather not use a card. Payment processes through a PCI-DSS compliant gateway with end-to-end encryption — standard security practice for an online checkout, not a distinguishing feature, but worth confirming since payment friction is a common reason an order stalls before a code ever gets applied. This doesn't change based on which code you're using, or which name, Oath Peptides or Oath Research, you know the company by; the checkout itself is the same one either way.
Ready to use a code?
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.
