BEHIND THE LINE
No fluff. Just answers.
Most peptide vendors hide their suppliers, dodge questions, and skip testing. We do the opposite. Every batch, every answer, on this page.
ABOUT NLL
Built by researchers, for researchers.
NLL was founded by researchers tired of opaque sourcing. We carry seven research compounds because that is what passes our lab. Anything below 99% purity is discarded.
Independent US labs run HPLC and LC-MS on every batch. Sterility and endotoxin verified. Reports public. Vials shipped same-day in plain packaging to US researchers only.
HOW WE TEST
Four checks per batch. No shortcuts.
-
01
HPLC purity
High-performance liquid chromatography. Confirms peptide identity and purity ≥99%.
-
02
LC-MS verification
Mass spectrometry confirms exact molecular weight matches the target peptide.
-
03
Sterility test
Lyophilized powder cultured. Negative for bacterial and fungal growth.
-
04
Endotoxin assay
Limulus amebocyte lysate (LAL) test. < 0.5 EU/mg.
