Every Melanotan-2 vendor that passes the gate, by PSR score
53 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. The certificate column is the vendor’s certificate for Melanotan-2 only. Affiliate status never affects the order (how we keep it separate).

These carry Melanotan-2 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.
