How to read this table
Package shows vial count × labeled mg per vial. Price per mg divides the listed package price by the total labeled milligrams, so single vials and multi-vial kits can be compared directly. “COA” shows the testing lab a vendor lists; click it to open the vendor's published certificate where one is available. A lower price per mg does not by itself establish that two listings are equivalent.
