How we test

Two analyses, independently run

Analysis is commissioned with an independent lab on the production runs we source. Pepta Labs does not test in-house.

TEST ONE

Purity

Reversed-phase HPLC measures how much of the material is the compound itself. The reported result for each compound is published on its own product page.

TEST TWO

Identity

Mass spectrometry confirms the compound is what the label says it is. It either matches or it doesn't, so it's reported as confirmed rather than as a percentage.

Documentation

Ask for the report

We send it to you directly. It isn't posted as a public download.

Email the compound name, and we'll send the documentation we have.

Write to support@peptalabs.com and the report comes back to you — before you order, if you want to see it first. It shows the reported purity and the identity confirmation.

Reports aren't published as files anyone can download, so each one goes to a named request rather than sitting on a page.

Questions

Common questions

How do you test purity?

Purity is measured by reversed-phase HPLC at an independent lab, commissioned on the production runs we source. Pepta Labs does not test in-house. The reported result for each compound is published on its product page.

How do you confirm identity?

By mass spectrometry, which checks that the compound matches what the label says. It either matches or it does not, so it is reported as confirmed rather than as a percentage.

Can I see the lab report before I order?

Yes. Email support@peptalabs.com with the compound name and we will send the available documentation. It is not posted as a public download.

How is it shipped and stored?

As lyophilized powder at ambient temperature, so no cold chain is required. Storage guidance is published on each product page. US shipping is free with no minimum and most orders ship the next business day.

Check the numbers.
Then order.

Every listed compound carries reported purity and identity documentation, available on request.
