How every lot earns its label
Four steps, in order, before a vial can be sold. Scroll through them.
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.
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.
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.
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.

Order before 2pm for same-day delivery in Tallahassee, cold-packed. Everywhere else in the US ships cold the same day with tracking.
Rep program
Our rep program is opening on Florida campuses. Reps carry a code worth 10% off a first order and are trained on one rule: it's research material, we don't talk dosing, we show you the report. Apply to be one of the first.

Why we started
We bought peptides from suppliers who couldn't say what was in them. So we sent them to a lab ourselves. There was no way to know before buying, and there should be.
Varsity Labs is the supplier we wanted to buy from. Every item has a report. Every label can be scanned. Someone answers the phone.
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.
