The Analytical Test Most Vendors Skip

Most peptide vendors have purity and identity COAs. Almost none test for endotoxin. That’s the gap Disclosed Labs fills — every product on our platform has a complete 5-panel analytical profile.

Why endotoxin testing matters

HPLC confirms purity. Endotoxin testing confirms the absence of LPS contamination — a common synthesis contaminant that confounds cell-based in-vitro assay results.

Every batch listed on our platform includes endotoxin testing as part of the complete 5-panel analytical profile. Vendors who want their products listed can submit samples for testing.
