**Two live codes, compared**
Oath Peptides discounts: exact savings by basket size
One code cuts 20% off a first order; another cuts 15% off any order, including repeats. Neither pays this site anything — the full saving goes to you.
- 425+ batches tested
- Free ship over $250
- Zero commission
- US orders only
Two codes are live at Oath Research checkout right now: one for first orders, one for every order after that. Below is exactly what each is worth, by basket size.
## Working Oath Research discount codes
| Code | Discount | Who | Conditions |
| --- | --- | --- | --- |
| `GRANT` | 20% off | new customers | New customers only. First order. |
| `GRANT15` | 15% off | everyone | No minimum. Applies to repeat orders. |
Both codes were tested against Oath Research's live checkout on 13 August 2026 and applied correctly. This site is an Oath Research deal page — it is paid nothing when you use a code, and there is no commission on either of them.

## The record behind the codes
A discount is only as good as what it's discounting. Oath tests every batch it ships and backs that with a written purity guarantee — refund or replacement if a batch doesn't hold up. None of that depends on which code you use, or whether you use one at all.
- **425+** — batches tested (as of Aug 2026)
- **99.63%** — avg. purity (trailing 12 months)
- **$250** — free-shipping line (US orders only)
- **0** — commission earned (by this site)
### Tested every batch
Oath tests every batch it ships, not a sample of production. As of August 2026, that's more than 425 certificates in the archive, with 99.63% average purity over the trailing twelve months. 250 of those 425 are searchable without an account; the rest require a login. Purity is measured by HPLC-UV, with LC-MS confirming identity, and each certificate names the lab: Freedom Diagnostics, an independent third-party partner.
### A refund if a batch misses spec
Product that doesn't meet its stated specification or purity qualifies for a refund or replacement — no restocking fee, 5 to 7 business days once approved. That's alongside standard coverage for transit damage, wrong items, and non-delivery. Opened or used product isn't covered, which is normal for research material, not specific to Oath.
### Dispatch, not delivery, is what's guaranteed
Most US orders ship by 2-day business air, usually UPS, with real-time tracking. Order before noon Mountain time on a weekday and it goes out the same day. Oath controls when a box leaves, not how fast the carrier moves it afterward. Shipping is free once an order clears $250, and Oath ships within the US only.
### No commission on either code
Neither the new-customer code nor the any-order code pays this site anything — no commission, no referral fee, no cut of the sale. The full discount goes to the buyer at checkout. This site exists to track Oath's live codes and work out what they're worth by basket size, not to earn from sending orders to Oath.
## Expired Oath codes
These codes used to work and don't anymore — none of them apply at checkout today. They're listed here so you're not left guessing why one failed.
| Code | Offer | Expired | Status |
| --- | --- | --- | --- |
| `OPDISCOUNT` | 15% off sitewide | 2026-04-09 | Expired |
| `PEPTIDE30` | 30% off, holiday | 2025-12-26 | Expired |
| `OATHLAB15` | 15% off first order | 2025-10-18 | Expired |
| `RESTOCK10` | $10 off restock orders | 2025-09-07 | Expired |
Two discount codes work at Oath Research checkout right now. One takes 20% off, but only if you have never ordered before. The other takes 15% off, and it works every time, new order or repeat. Neither code costs anything to use, and neither pays this site a cent — there's no referral fee, no commission, no cut of the sale. Below is a straight comparison: three basket sizes, from one vial to a five-vial order, with the exact dollar amount each code takes off. There's also a separate note on Oath's $250 free-shipping line, since that's a different mechanic from either code. Pick the row that matches your order, pick the code that matches your customer status, and you have your answer before you reach checkout.
## The three-basket comparison
### The three-basket comparison
Same two codes, three different order sizes. Each column shows what the order costs after that code is applied — pick your basket, pick your code, read the number.
| Basket | What's in it | List price | 20% new-customer code | 15% any-order code | Free shipping ($250+) |
|---|---|---|---|---|---|
| One vial | BPC-157 | $40.00 | $32.00 (save $8.00) | $34.00 (save $6.00) | No |
| Mid-size | GHK-Cu, KPV, Melanotan 2 | $150.00 | $120.00 (save $30.00) | $127.50 (save $22.50) | No |
| Five-vial | BPC-157, AOD9604, CJC-1295/Ipamorelin, KPV, Epithalon | $330.00 | $264.00 (save $66.00) | $280.50 (save $49.50) | Yes |
Read the columns as separate routes, not as a stack. Nobody applies both codes to one order — pick the one your account status allows and use that. The free-shipping column is its own mechanic: it is about order size, not about which code you used, and both discounted totals in the five-vial row still clear $250 on their own.
## New customer or returning — which code applies
### New customer or returning — which code applies
| | New-customer code | Any-order code |
|---|---|---|
| Discount | 20% | 15% |
| Who can use it | First-time customers only | Anyone, including repeat orders |
| Minimum order | None | None |
| Beats Oath's own new-account offer? | Yes — Oath's site-wide banner offers 15% for new accounts | Matches it |
If you have ordered from Oath before, the new-customer code will not apply — Oath's checkout checks that against your account or the email on the order, not against how you describe yourself, so there is no way to talk your way past it. Use the any-order code instead. It is the evergreen option: no minimum order size, no stated expiration, and it applies on a second order the same way it applies on a first.
The comparison is not close. Oath's own site-wide banner already advertises 15% off for new accounts, so the any-order code simply matches what Oath already offers anyone who signs up. The new-customer code beats that by five points — it is a better version of an offer Oath is already making, which is the honest reason to use it instead of leaving the field blank and taking Oath's own on-site rate.
## Where the $250 free-shipping line sits
### Where the $250 free-shipping line sits
Oath ships most US orders by 2-day business air, usually UPS, and orders placed before noon Mountain time on a weekday go out the same day. That is a dispatch guarantee, not a delivery guarantee — Oath commits to when the box leaves the warehouse, not to when the carrier sets it down on a porch, and the difference matters if you are timing an order around anything.
Shipping itself is free once an order clears $250. That is a separate rule from either discount code: it is about how much is in the basket, not which code — if any — you used to check out. In the comparison above, the five-vial basket clears that line at both $264.00 and $280.50, the totals after either code, so it ships free either way. The one-vial and mid-size baskets stay under $250 even before a code is applied, so shipping is not free on those, regardless of which code is used or whether one is used at all.
Oath ships to US addresses only. There is no international option at checkout, so a basket built around the $250 line only matters if the delivery address is inside the United States to begin with.
## One code per order, and nothing paid to anyone
### One code per order, and nothing paid to anyone
Use one code per order — the new-customer code or the any-order code, never both. There is no combined rate to reach for: this site has not seen one, does not present one, and would say so plainly if that changed. Entering a second code after the first is applied does not stack the discount; it either gets rejected or replaces the first one, depending on how the checkout handles it.
Neither code pays this site anything. No commission, no referral fee, no cut of the sale — the saving goes to the buyer, in full, at checkout. That is worth stating plainly, because coupon pages are sometimes assumed to be running an affiliate arrangement behind the numbers; this one is not, and there is nothing further to disclose beyond that fact.
Applied to the comparison above: a five-vial basket at $330.00 becomes either $264.00 with the new-customer code or $280.50 with the any-order code — never both at once, and never a blended rate somewhere in between. Pick the code your account status actually qualifies for, and that single number is the one that shows up at checkout.
## 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.
