Where the ones who actually pick up.

PeptPurity Inc supplies highly purified peptides, proteins and amino acid derivatives to laboratories and researchers across the United States. Every lot is independently tested and ships with its certificate.

That part, plenty of suppliers will tell you. Here's what makes us different: call us and a person answers. Not a queue, not a ticket number, not a form that disappears into a shared inbox. A person, in Ohio, who can see your order and fix the problem while you're still on the line.

One number. No phone tree.

It rings at a desk, not a call centre. You can check an order, ask about a lot, request a certificate, or place a new order start to finish — and yes, we can take payment right there on the call if that's easier than checking out online.

Why Choose Us

What you get when you order from PeptPurity

We're a Midwest company, and we run the business the way people here expect to be treated — straightforwardly, and by someone who'll stand behind what they sold you.

Customer service is the product

Anyone can list vials on a website. What you're actually buying is whether someone answers when something goes sideways. We built the company around that, and we'd rather you call than wonder.

Dispatched from Columbus

Orders leave our Columbus facility, which sits in one of the country's main distribution corridors — a large share of the US population is within about a day's drive. Nothing has to cross the continent to reach you.

Documentation on every lot

Independent HPLC-UV purity and LC-MS identity confirmation, with the signed certificate available to download before you ever place the order. Nothing is asked to be taken on faith.

Consistency you can plan around

Lot-to-lot consistency matters more than a headline purity figure. We hold to tight quality protocols so the vial you order next quarter matches the one on your bench today.
