Every ARA-290 vendor that passes the gate, by PSR score
18 vendors, highest PSR score first; equal scores are listed alphabetically. Price per mg is matched at 10mg, the size most carriers sell, so vials compare like for like.

Listed separately: 9 vendors outside the ranking
These carry ARA-290 but do not meet our testing gate, so they are never placed in the ranking above, whatever their score. The gate records what we could verify; it is not a finding of a quality or safety problem.
