HPLC Purity Analysis
High-performance liquid chromatography measures actual compound concentration. Current catalog results: 99%+. Instrument data and chromatogram included in every COA — not just the percentage.
Lab Tests & Certificates of Analysis
Every batch independently tested. Every COA publicly available.
Freedom Diagnostics tests each batch for purity, identity, and endotoxin levels. Every COA is publicly searchable on their website by accession number — scan the QR code on your vial or use the lookup links below.
Mass Spectrometry Identity
Mass spectrometry confirms molecular weight and fragmentation pattern — the only reliable way to verify a compound is what the label says it is. Every batch confirmed before listing.
LAL Endotoxin Screening
The limulus amebocyte lysate assay detects bacterial endotoxin contamination. Most research peptide suppliers do not perform this test. Every batch here passes LAL screening before it ships.
Why independent testing matters
A supplier testing their own product is not the same as an independent laboratory testing it.
Freedom Diagnostics operates independently of Delta Peps. Their analysts run the tests, their instruments generate the data, and their name appears on the certificate. You are not taking our word for the purity number — you are reading an independent laboratory report.
That distinction is the difference between a research-grade material and a compound with a number printed on a label.
