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.
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.
Every order ships in an insulated pack with ice and a temperature strip. Lot number and fill date on every label, and a plain outer box. Just what you ordered, the way a research order should arrive.
Bundled under the price of the vials, packed together, with bacteriostatic water in the box.
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 and sealed
Insulated box, temperature strip, plain exterior. The QR on the label opens the report you just read about.
Lot lookup
Check the numbers before you open the box.
Type the six-digit lot number printed on the label, or a compound name, and every matching report lists below with a link to its signed certificate.
Certificates are issued by ILS Laboratories to Sobe, the manufacturing affiliate in Palm Beach County, FL that fills every Varsity Labs vial, so the name on the report is Sobe and the vials are ours. Lot numbers are production-run codes (month and year), so compounds filled in the same run share one; each certificate carries its own COA number and verification code.
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 in Florida. Then everywhere. We want a public lab report to become the minimum anyone accepts from a research supplier.
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.

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 affiliates 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.
