Independent peptide sample testing

We publish and explain available laboratory records. This page is informational: we are not accepting sample shipments, taking testing payments, or promising a testing service.

What a test can establish

HPLC can measure chromatographic purity; mass spectrometry can help assess identity. Quantity, sterility and endotoxin testing are different assessments. A purity percentage alone does not establish safety, suitability for human use or the quality of a different batch.

Before contacting a laboratory

• Ask the laboratory directly which methods and sample types it supports.
• Confirm its current requirements, price and handling instructions before sending anything.
• Keep the vendor name, batch/lot identifier and original certificate so results can be traced to the sample.
