A batch report can cover thousands of vials filled over months. A lot report covers the vials filled from one run, which is the only report that says anything about yours.

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.

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.
