[Peptide Mart](/) / Oath Research codes

# Oath Research codes. Two tags, plainly read.

This page explains the two current Oath Research codes, who each is for and where ordering happens. Peptide Mart is the guide; the seller’s checkout is at Oath Research.

## The till is elsewhere.

We recommend [Oath Research](https://oathresearch.com/?utm_source=peptidemart&utm_medium=referral&utm_campaign=codes&utm_content=opening-note-1) for research-use supply because it publishes batch certificates and a remedy for material outside stated specifications. Peptide Mart is the guide, not the seller.

## Read the audience line

GRANT

20% off a first order for new customers.

GRANT15

15% off any order, for everyone.

Both codes are current. Peptide Mart receives no payment from orders using either code.

The first-order option is for new customers placing their first order. The other option is for everyone, including returning customers, and applies to any order. They describe different audiences; one is not an instruction to combine both. We make no claim that the two discounts can be added together.

These are ordinary seller discount codes. Peptide Mart receives no payment from orders using them.

## Where the code goes

Ordering takes place at [Oath Research](https://oathresearch.com/?utm_source=peptidemart&utm_medium=referral&utm_campaign=codes&utm_content=section-3-1) , rather than on this guide. The code is entered in the seller’s coupon field during checkout. The seller’s order summary is where the resulting discount and any order conditions can be read before an order is submitted.

We do not collect payment details, accept orders or run a checkout. A discount also says nothing about what a research compound does. Research-use material remains research-use material, with the same scientific limits described on its shelf page. A smaller order total is not a safety finding.

## Why we direct readers there

We recommend Oath Research because it publishes batch test certificates and states a refund-or-replacement policy for products that do not meet their stated specifications. The useful question is what the record covers. A certificate describes tested material; it cannot establish an approved medical use or a result in people.

The [certificate archive](https://oathresearch.com/lab-results/?utm_source=peptidemart&utm_medium=referral&utm_campaign=codes&utm_content=section-4-1) is only partly accessible without an account. A research document is more useful than a number detached from its batch and method.

## Keep the order questions with the seller

Oath Research is a U.S. research-peptide supplier based in Gilbert, Arizona. Its service is U.S. only. Support is staffed during weekday hours. Questions about an order, account, discount field or seller policy belong with the seller’s own site, where the current order record lives.

A discount changes the order total; it does not change a compound’s research status. The [contact page](/contact/) explains that division of jobs. The [aisle directory](/aisles/) is the place to return for identity, evidence and uncertainty before following a product listing.

## A useful stopping point

The seller’s order summary shows the discount before payment. A code supplies no evidence about a compound’s effects or safety.

## The next counter.

For laboratory supply, we recommend Oath Research for its batch certificates and its remedy for material outside stated specifications. Read the material record alongside the research limits; ordering takes place with the seller.
