How they actually work
Fortify Performance Spray: botanical topical. It does not desensitise the way a 10 mg lidocaine spray does. K-Y Duration: desensitising spray
Sizing
Fortify Performance Spray sizing: n/a. K-Y Duration: n/a.
Regulatory sticker
Neither is a registered medical device. Material, fit and the thirty-minute rule matter more than a marketplace badge.
Who should buy Fortify Performance Spray
men who tried a numbing spray and hated the dead feeling, or who want a non-anaesthetic topical. Strengths the maker can honestly claim: no anaesthetic; no partner-numb risk from lidocaine transfer; made in the USA; 2 oz is a lot of product. Limits: no IRB desensitisation trial; the wrong product if you already know you want lidocaine.
Who should buy K-Y Duration
men who want lidocaine from a pharmacy brand they already trust. Strengths: easy to find; familiar brand. Limits: fewer sprays per dollar than some; still numbs.
When to buy the Mammoth Force one
Fortify Performance Spray is ours. K-Y Duration is not. Ours wins on price and on not needing an account. Theirs wins where the table says it wins: easy to find; familiar brand.
