Most people buy a research vial on two numbers. The specification has fourteen lines.

Everyone prices a research vial per milligram
Price per milligram treats every milligram as identical. It cannot tell you what is actually in the vial, how much of the powder is the material you paid for, or which lot got tested.

Four vials, one category, one price. Not one purchase
Four listings under the same heading, with four different sets of analytical controls behind them. The category tells you nothing. The listing is the only place that does.
Read the breakdown →Supplier standards
Everyone writes lab tested. Ask which lab, which lot, which method
Two words doing the work of three separate claims. Here is what each one has to answer before it means anything, and what it looks like when a supplier can answer all three.

A certificate is easy to publish. Proving it belongs to your vial is the hard part
A PDF on a website is evidence about a batch that existed once. It says nothing about the vial in your hand unless the lot numbers match.
Read the breakdown →Purity
99% pure is a ratio. It does not tell you how much is in the vial
Purity is a percentage. Net content is an amount. A vial can be 99% pure and hold less than the label says, with the balance salt, water and counterion.
