Prices are what the vendor listed when we last looked, not a live quote. Comparisons are per milligram against the median across every vendor we track. Outbound links carry no affiliate parameters.

Read, but not published

A listing counts toward the index only once the size and count are certain — a guess about whether “10 x 10mg” means 10 mg or 100 mg is a tenfold error. These are shown because hiding them would make the catalogue look smaller than it is.

TermsListing is not endorsement. We take no payment for inclusion or position, hold no affiliate relationship with any seller, and have not tested what is in their vials. Batch disclosure is a signal about process, not a guarantee about contents.

Assessing a vendor yourself

A price is one signal, and not the important one. The method matters more than any verdict we could give you.
