About us
Oath Peptides is a US research peptide store based in Gilbert, Arizona. We sell 56 lab compounds, test every batch, and try to make each product page the most accurate one you’ll find.
Buying research peptides online can be frustrating. Listings copy each other, CAS numbers get mixed up, and it’s hard to tell what was tested. We started Oath Peptides to fix the parts we could control: test every batch, label it clearly, and write product pages that hold up when you check them.
The name is the point. An oath is a promise you keep, and ours is simple. If it’s on the site, it passed testing, and the page tells you what it is.
We carry single peptides like BPC-157, TB-500 and GHK-Cu, seven peptide blends, 15 bioregulator peptides, and a few lab compounds that aren’t peptides at all, like NAD+. Everything is sold for laboratory research only.

The short version of what happens between a batch arriving and a box reaching your lab.
Sealed vials, labeled with the compound and amount. Product pages add the sequence, formula and PubChem link.
We won’t list a batch that hasn’t been tested, and we won’t copy product facts from other sites without checking them. We also won’t give dosing or medical advice, because everything we sell is for laboratory research only. If you’re about to order and something on a product page doesn’t add up, tell us. We’d rather fix a page than have you guess.

There are a lot of places to buy research peptides. Most of them sell the same compounds. What’s different about us is how much we tell you. Each product page is written from primary sources, and each links to NIH PubChem so you can check the formula and weight against the public record. Where other listings get a number wrong, we say so.
We’re also small enough that a person on the team reads every email. If you have a question about a product or an order, write to us and you’ll get a straight answer.
We built the store for university and independent labs, and for researchers who order regularly and want the same batch quality every time. A single vial is a good way to check a product, and the 6 or 12 packs make sense once you know what you need. If you’re ordering for a lab and want to set up something regular, get in touch and we’ll talk it through.
