Our research peptides are made in the United States to clearly defined specifications for identity, purity and consistency.
Our Standards →Every lot goes to ILS Laboratories, an ISO 17025 accredited lab, for HPLC purity, identity, endotoxin, sterility and heavy metals.
How We Test →Type the lot number printed on your label to pull up its certificate of analysis before you begin your research.
Search Test Results →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.

Bundled under the price of the vials, packed cold together, with bacteriostatic water in the box.
Four steps, in order, before a vial can be sold. Scroll through them.
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.
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.
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.
Insulated box, ice, temperature strip, plain exterior. The QR on the label opens the report you just read about.
Every lot ships with its own certificate. This is one of ours, and how to find yours.
Type the six-digit lot number printed on the label, or a compound name. See every report and the original PDFs.

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.

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