It’s the right question to ask about any research peptide vendor, including us. So here is everything you can check yourself, without taking our word for anything.

## The company is real
Vault Tech Labs LLC is a Wyoming limited liability company. Wyoming business records are public, so you can look us up with the Wyoming Secretary of State. Our mailing address is in the footer of every page, and every order is handled through orders@vaulttechlabs.com.

## The lab is named
Every lot we sell is tested by an independent analytical lab, and that lab is named on the certificate, along with the analysis date and the lab director’s sign-off. You can look the lab up and contact it directly.

## Every lot’s certificate is public
– **Purity:** HPLC purity, measured against a 95% spec.
– **Identity:** Proof the sample is the compound on the label, by HPLC retention-time match or LC-MS mass spectrometry.
– **Your lot:** A lot number that matches the label on your vial, character for character.
– **Published first:** Each certificate goes up before a single order from that lot ships.

Every certificate is in our [COA archive](/coa/), searchable by lot ID or COA number.

## Check the result with the lab, not with us
Each certificate carries a QR code and an access code. Scan it, or enter the code at the lab’s own verification portal, and you are reading the lab’s record of the test. If our page and the lab’s record ever disagree, believe the lab, and tell us.

## Our record, failures included
Before we opened, 16 lots went to the lab. 7 passed. 3 failed, and 6 never came back with a certificate. None of those 9 are for sale, and they never will be. That is why we opened months later than we planned.

## What we don’t do
– Sell anything without a passing certificate.
– Make health claims, or answer questions about use or dosing. Our products are for laboratory research use only.
– Sell GLP-1 class compounds.
– Take payment through personal payment apps. Checkout runs on Lüt, a payment processor, as Pay By Bank.

## Check any vendor the same way
Ask every supplier for the same six things: a named, accredited lab, a lot number that matches your label, purity with its spec, an identity test and its method, a chromatogram, and a way to verify the result with the lab. Our guide, [How to Read a Peptide Certificate of Analysis](/how-to-read-a-peptide-coa/), walks through each one, and [our method page](/method/) shows how we test every lot.

Most buyers look at a COA, see “99.4% purity,” and stop there. A real Certificate of Analysis has several parts, and each one tells you something different.

## The HPLC chromatogram
This is the headline test. Reverse-phase high-performance liquid chromatography separates the target peptide from related impurities. The purity figure is the area of the main peak as a share of all peptide peaks. Look at the chromatogram itself, not just the number: shoulder peaks or side peaks at 1 to 2% of the main peak are impurities.

## Identity
The COA should confirm the compound is what the label says. Most certificates do this by matching the HPLC retention time to a reference standard. Some also confirm identity by mass spectrometry (LC-MS), which checks the molecular weight directly and is the stronger test.

## Net content
Some certificates report net peptide content: the milligrams of peptide measured in the vial. It is usually a report-only figure, not a pass or fail line, and it lets you compare what was measured with what the label says. Purity and content are two different numbers.

## What research-grade COAs usually do not include
Sterility, endotoxin, and heavy-metal panels are pharmaceutical-release tests, and most research-grade certificates, ours included, do not run them. Research-use material is not a sterile pharmaceutical product and should never be marketed as one.

## Lab identification and verification
**Who issued the COA?** Is the lab named? Is the certificate tied to your specific lot? Does it carry an access code or QR code so you can check it with the lab directly? If any of these are missing, you are trusting the brand’s marketing, not the data.
