# About Oath Discount Codes *About This Oath Research Discount Log | October 2026* > What this site is: an Oath Research discount-code page, updated when codes change, earning no commission on either code. Not a review, not Oath itself. This is a discount-code site for Oath Research, a US research-peptide vendor. It exists to list the codes that currently work at Oath's checkout, track when they were last checked, and keep a separate record of codes that no longer apply. It is not Oath Research, and it does not present itself as a customer review or a lab test — it is a deal page, openly built around one vendor, updated when its codes change. Using either code on this site pays this site nothing. There is no commission, no referral fee, and no payment of any kind tied to either code, from Oath Research or from anyone else. That fact does not change based on which code is used or how often. ## What This Site Does Two things, on a schedule: check whether the two current Oath Research discount codes still work at checkout, and keep a dated record of that check. When a code stops working, or a new one starts, this page and the home page are the ones that change. The expired-codes table exists for the same reason — codes end, and a stale claim of “always current” is less useful than a dated record of what changed and when. This site does not review Oath Research's products, does not test peptides, and does not have an opinion on which compound a reader should choose. The why-oath page describes Oath's own published testing and returns record, sourced from Oath's own pages, because a discount is only useful if the underlying purchase holds up — not because this site independently evaluated the product. ## What This Site Doesn't Do No dosing information, no reconstitution instructions, no protocols, and no claims about using any Oath Research product on a person or an animal. Oath Research sells research-use material, and this site treats it as exactly that: a research-use product with a price, a testing record, and a checkout, not a treatment or a supplement. No commission, referral fee, or payment of any kind is earned when either code is used — that applies across every page on this site, not just this one. No customer testimonials are invented or implied; nothing here claims to speak for anyone who has ordered from Oath Research. Where a claim about Oath Research appears on this site, it traces to Oath's own published pages, checked and dated, not to this site's own testing or opinion. ## 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.
