A curated selection from vetted manufacturers — priced transparently, tested before every ship.
Every lot arrives with its chromatogram.
We don't manufacture — we vet. Each brand clears an independent purity audit before it lists, and every lot is re-tested before it ships. The data lives on the page, not behind a paywall.
HPLC + mass-spec
Identity and ≥98% purity floor confirmed on every batch by an ISO-accredited lab.
Second-lab confirmation
A sample from each lot goes to a second independent lab. Both COAs ship in the box.
