WELCOME
We publish the proof — not the promise. Every lot characterized by HPLC and mass spectrometry.
Beyond Purity — What 99% pure doesn't tell you. Purity testing measures one thing; we test for the four things it can't see.
01 — Endotoxins: toxic fragments left behind by dead bacteria. Heat-stable, survive sterilization, biologically active on their own.
02 — Sterility: the absence of living microbial contamination, cultured against USP standards.
03 — Heavy Metals: lead, arsenic, mercury, and cadmium introduced during synthesis. Detected only by ICP-MS.
04 — Batch Consistency: verification that every batch matches the last. Multi-sample, reference-tested, reproducibility audited.
