Lab standards

Transparency means saying exactly what a certificate is. Here is what ours are, and what they are not.

Who issued the certificates

The certificates in our lab results library were issued by independent laboratories, currently Krause Analytical, BT Labs and Freedom Diagnostics, to our supplier for the production lots we stock. None of those labs is owned by or affiliated with Kits Peptides, and we do not currently commission testing in our own name. The client named on a PDF is therefore the supplier, not us, and our batch code is the internal receipt reference we assign to that production lot; it does not appear on the document.

Where to read them

Each supplier certificate is published on the certificates page, including purity and measured mass where the lab reported them.

What the certificates report

• Purity: by HPLC, reported as a percentage of the target compound.
• Identity: by mass spectrometry, confirming the molecule matches the label.
• Mass: measured content per vial versus the label claim.

Per-lot certificates

Each order records the batch that filled it. Where that batch has a published certificate, it is the certificate issued for the production lot the material came from. Lots without a certificate stay off the library, and product pages make no testing claim for them.
