# Why Order From Oath Research > The testing record, purity guarantee, and shipping policy behind Oath Research, formerly called Oath Peptides, laid out here in plain, checkable, dated terms. Oath Research — the company still listed as Oath Peptides on some older pages and forum threads — has built its case for trust on one thing: it tests every batch it sells and makes the paperwork available to check. That's a higher bar than a lot of research-peptide suppliers clear, where testing claims are common but the underlying certificate often isn't. This page lays out what Oath actually publishes, in plain terms: how many batches have been tested, what the average purity has run over the last year, what a certificate covers and doesn't, and what happens if a shipment doesn't meet its stated specification. None of this is marketing copy pulled from a product page — it's drawn from what Oath states on its own site, attributed as such, alongside what its refund policy actually promises if the testing claim turns out to be wrong for a given order. ## A certificate for every batch Oath's testing program covers more than 425 batches as of August 2026, and the number keeps climbing as new batches ship — it's an active, ongoing program rather than a one-time claim frozen at a single count. Purity is measured by HPLC-UV, with LC-MS used to confirm identity — standard analytical methods for this kind of verification, not a proprietary or unverifiable process. Averaged over the trailing twelve months, Oath reports 99.63% purity across the batches it's tested. That figure moves as new results come in, which is worth knowing if you see a slightly different number elsewhere; treat anything without a stated time window as less precise than the twelve-month average. The lab behind the numbers is Freedom Diagnostics, named directly on each certificate as the independent third-party testing partner — Oath doesn't test its own products in-house and call it verification, which is a meaningfully different structure than a supplier grading its own work. ## What you can actually check yourself Oath publishes its certificate archive at [oathresearch.com/lab-results](https://oathresearch.com/lab-results), and as of this writing, 250 of the 425 certificates on file are searchable by peptide name or batch number without creating an account. The remaining certificates require logging in to view — worth knowing up front, because a claim that the whole archive is open to anyone doesn't hold up, and this site isn't going to tell you otherwise. What matters is that the public subset is real and checkable in a couple of clicks: pick a peptide, find a batch, and read the lab's own report rather than taking a vendor's word for a purity number. Oath's stated endotoxin standard is USP <85>, and its lab-results page states that endotoxin safety is confirmed by an independent laboratory — that's Oath's claim about its own process, cited here as such rather than something independently verified batch by batch. Worth checking for yourself the next time you're deciding what to order. ## The purity guarantee has teeth Testing claims are only as useful as what happens when a specific order falls short, and this is where Oath's policy is stronger than most research suppliers': if a product doesn't meet its stated specifications or purity, that order qualifies for a refund or a replacement. So does shipping damage documented with photos within 48 hours, a wrong item, a non-delivery despite tracking showing otherwise, or a duplicate order caught before it ships. There's no restocking fee on an approved return, and approved refunds process in 5 to 7 business days, with an initial response typically inside 24 to 48 hours. The one thing the policy doesn't cover is a simple change of mind on opened or used product — standard for research material, and worth knowing before you order rather than after. Tying a refund policy directly to the purity claim is what turns a testing program from a marketing point into something you can actually hold the company to. ## What Oath says about its own process Oath's own about page states that its peptides are synthesized under ISO-certified protocols. That's Oath's claim about its manufacturing process, not a certification this page has verified, so it's worth treating as company-stated rather than lab-confirmed — the same distinction that matters for the purity numbers above and for the endotoxin standard mentioned earlier on this page. Between the batch-level testing, the named lab partner, the searchable certificate archive, and a refund policy that actually references purity, Oath sits among the more thorough U.S. research-peptide vendors on testing and transparency specifically. That's a comparative statement about documentation, not a claim that no other vendor tests its products; it's simply where Oath's own published record puts it against typical practice in the category, and it's the standard this page has tried to hold every claim on it to as well — attributed where it's Oath's word, and linked to the archive where a reader can check it directly. ## Ready to use a code?
