This is a buying review of K-Y Duration, not a lab test. We have not run a 12-week trial. We are placing the public product against the job (a topical spray) and against what this shop actually sells.
Verdict
Buy K-Y Duration if men who want lidocaine from a pharmacy brand they already trust.
Do not buy K-Y Duration if men avoiding anaesthetics.
Listed price: check the maker’s current listing (commonly ~$20; confirm at source).

How it compares to what we sell
Fortify Performance Spray ($49.99): a 2 oz USA-made botanical topical. Store page says it does not numb and is not lidocaine
K-Y Duration wins on easy to find. We win on price and on not requiring you to join a medical-device or telehealth stack to find out if the job is even yours.

Who this review is not for
If you already own K-Y Duration and it works, stop shopping. If you wanted a vibrating cock ring, a penis pump, or lidocaine and this product is not that, this review will not launder it into that product.
Safety
Fortify’s store page says it does not numb and is not a lidocaine spray. Read the bottle. If a partner will have oral contact, follow the label.
