Why don’t you show prices?

Because we don’t show them until you’ve told us you’re a researcher. That is the whole point of the account.

You confirm you are 21 or older, and that nothing you buy will be used in or on humans or animals. It takes about a minute, it costs nothing, and your confirmation stays current for 12 months.

Everything else stays open. Every compound, every purity figure and every lot number is readable without an account — we hold back the numbers you would order from, not the evidence you would check us on.
