Every Sermorelin vendor that passes the gate, by PSR score
43 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 Sermorelin only. Affiliate status never affects the order (how we keep it separate).

Listed separately: 19 vendors outside the ranking
These carry Sermorelin 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.
