Made in the USA

Our research peptides are made in the United States to clearly defined specifications for identity, purity and consistency.

Our Standards →

Real Results.
Every Lot.
Published Publicly.

Before a vial gets a label, samples from its lot go to an independent lab. The certificate is posted the day it's signed, pass or hold, and the QR code on the label opens it. No marketing numbers. Just results you can check yourself.

How every lot earns its label

Four steps, in order, before a vial can be sold. Scroll through them.

  1. 01

    Filled and numbered

    A lot is one production run. Every vial from it carries that run's number and fill date, so a report always points at the exact vials you hold.

  2. 02

    Sent to the lab

    Before labels, samples go to an independent laboratory for HPLC purity, mass-spec identity, endotoxin, sterility and heavy metals. We don't choose the numbers.

  3. 03

    Published, pass or hold

    The certificate goes on the reports page the day it's signed. A pass ships. Anything else stays on hold where everyone can see it.

  4. 04

    Packed cold

    Insulated box, ice, temperature strip, plain exterior. The QR on the label opens the report you just read about.

See a real report

Every lot ships with its own certificate. This is one of ours, and how to find yours.

A row of Varsity Labs vials on a lab rack

Same Standard.
Every Vial.
Every Time.

We bought peptides from suppliers who couldn't say what was in them, so we sent them to a lab ourselves. Varsity Labs is the supplier we wanted to buy from. Every lot is held to the same purity threshold, tested the same way and documented the same way.

Research use policy

What we sell

Varsity Labs supplies compounds for in vitro laboratory research. Every product is sold as a research chemical. None is a drug, dietary supplement, food, cosmetic or medical device, and none has been evaluated or approved by the U.S. Food and Drug Administration for any use.

Not for people or animals

Products are not for human or veterinary use, not for in vivo use in humans or animals, and not for diagnostic, therapeutic or clinical procedures. Nothing on this site is intended to diagnose, treat, cure, mitigate or prevent any disease or condition, and nothing here should be read as a claim that a product does.

Who can buy

Orders are accepted only from buyers who are at least 21 and confirm they are qualified researchers, or are purchasing on behalf of a research institution or entity, for in vitro use. We may ask for verification and may refuse or cancel any order.

Information on this site

Product pages describe identity, composition, purity, handling and storage. They are educational. Lab reports document what is in the vial, not what it does. Our reps and support team do not give handling, dosing or use guidance of any kind.

Your responsibility

The buyer is responsible for compliance with all laws and regulations that apply to purchasing, handling and using research compounds where they are. By ordering, you agree to these terms.

About Varsity Labs

Varsity Labs is a U.S. supplier of research peptides, tested lot by lot at an independent ISO/IEC 17025 laboratory. Every certificate is public. Every vial can be scanned to its report. We're built for people who want to see the numbers before they buy.

Our mission

Peptides you can verify.

Every lot is tested by an accredited US lab before it gets a label. The report is posted where anyone can read it. If a lot fails, it doesn't ship.

Our commitment

The truth on every vial.

Lot number and a QR code to the lab report on the label. A real person answers. If an independent test ever disagrees with our report, you get a full refund plus the cost of your test.

Our vision

Make "show me the report" the normal question.

Start on campus. Then every campus. We want a public lab report to become the minimum anyone accepts from a research supplier.
