Research materials you don’t have to take on trust.
Anvil Aminos supplies research-grade peptides and related reference materials for in vitro laboratory work. We’re based in Southern California and operated by Anvil Holdings LLC.
The research-compound market runs on labels. Almost anyone can print “99% pure” on a vial, and a buyer usually has no way to check whether it’s true. We started Anvil Aminos to work the other way around: lead with the data, and let the paperwork do the talking.
So every lot we sell goes to an independent laboratory before it ever reaches the catalog. That lab runs the purity, identity, and endotoxin tests, and the results come back on a Certificate of Analysis tied to that specific lot. The COA ships with your order and carries a code you can use to confirm the results with the lab yourself, not just with us. If a lot doesn’t meet the standard, it doesn’t get listed and it doesn’t get sold somewhere else quietly — it’s rejected.
Everything else is built to stay out of your way. Orders are packed and shipped from our Southern California facility, usually the same day when they’re placed before noon Pacific, and a real person answers support email on weekdays. The goal is simple: make the quality checkable, and make the buying straightforward.
Independent testing
We don't grade our own work. Every lot is tested by an independent, third-party lab, so a result can't be adjusted to push a batch through.
A COA for every lot
Each order ships with the Certificate of Analysis for the exact lot you receive, and you can verify it directly with the issuing lab.
One standard
Three tests — HPLC purity, mass-spec identity, and an LAL endotoxin screen — and a 99% purity floor. A lot that doesn't clear all three doesn't ship.
