If you are choosing between Promescent Delay Spray and Stud 100, the split is not branding.

Stud 100 (check the maker’s current listing) is men who want lidocaine at the lowest cost and will wipe carefully.

men who want the best-documented desensitising spray and accept numbness. Strengths the maker can honestly claim: named trial; urologist-adjacent brand; anti-transfer pitch; owns the ‘delay spray’ SERP. Limits: it numbs; cost per spray is high; wrong category if you refuse anaesthetics.
