Why Purivial

Tested like it matters.

Most sellers hand you a generic PDF and call it a day. We test every batch by HPLC and mass spec, re-test random vials at an independent lab, and let you verify the result yourself. Held to that standard, and still priced below the typical market.

The Purivial standard

Every vial is
provable.

Most sellers send a generic PDF. We give you the certificate for your actual lot, with purity, identity, and a report number you can check yourself.

No reused COAs. No mystery compounds. You see the data before you order, not after.

How we verify

Paperwork is easy to fake. Our process isn't.

01

Batch-specific COA

Lot number, test date, and the certificate for the exact vial you receive. Never a generic sample.

02

HPLC + Mass-Spec

Purity tells you it's clean. Mass-spec proves it's the right molecule. We require both.

03

Independent re-test

We pull random vials and send them to an outside lab. If the numbers don't match, the batch doesn't ship.

FAQ

What buyers ask first

Does Purivial provide a COA for each batch?

Yes. Every product ships with a batch-specific Certificate of Analysis showing HPLC purity and mass-spec identity for that exact lot, plus an independent report you can verify yourself.

How does Purivial verify purity and identity?

HPLC confirms purity at 99 percent or higher, and mass spectrometry confirms the molecule is exactly what the label says. We also pull random vials and re-test them at an independent lab.

How are the peptides shipped and stored?

They ship as lyophilized freeze-dried powder, cold and tracked. Store at 2 to 8 degrees Celsius and reconstitute with bacteriostatic water before use.

What does research use only mean?

Products are sold for laboratory and research purposes only and are not for human consumption. Statements have not been evaluated by the FDA.

Which peptides does Purivial carry?

The launch lineup is Tirzepatide, Semaglutide, Retatrutide, BPC-157, TB-500, GHK-Cu, Glutathione, and NAD+.
