Quest log

The lot number, release date, purity by HPLC, identity by mass spec, water content and endotoxin. In the spec every certificate is a sample marked SPECIMEN.

Type the lot number from the label into the lot lookup. It reads ARB- and four digits.

The live store names the testing lab on every certificate. The spec leaves the lab out.

Each lot is tested on its own, so you can compare lots side by side in the library.

Every vial in the bag counts. Three vials take 10% off the whole bag, five take 15% and eight take 20%. At Rack III, level 1 starts at two vials.

Over $200, or over $150 from Rack II.

That is set in the shipping policy.

The refund policy covers damaged items, wrong items and lots that do not match their certificate.
