Many men, when first hearing about delay spray, have a question in their minds: will it feel like being numbed by anesthesia, completely devoid of sensation? If that's the case, what's the point of prolonging the time?
Today, we're talking about the Japanese Maruei Kenkyu Delay Spray for Men, Large Bottle 10ml Purple Gold Edition Upgraded Version, whose main selling point is "no numbness." I used it for three weeks, tested it in different scenarios, and I'll lay out the real experience and the underlying logic clearly in one go.
Bottom line first: No numbness is real, but only if you use it correctly.
The core of this spray lies in 11 Chinese herbal extracts: Damiana, Cnidium, Epimedium, Cinnamon, Raspberry, Clove, Honeysuckle, Cistanche, Maca, Chinese Chive, and Purple Cloud Flower. It doesn't follow the "numb the nerves" route, but instead works gently on the epidermal stratum corneum to reduce sensitivity, while ingredients like Maca and Epimedium help boost local blood circulation to maintain firmness.
Why do many delay products cause numbness?
Many cheap products on the market rely on alcohol or Benzocaine (a local anesthetic) to work. The principle is to forcibly block nerve signals, at the cost of losing sensation and ruining the partner's experience. The Purple Gold Edition contains no alcohol and no anesthetic ingredients, so there's no "anesthetized" feeling. I tried it—20 seconds after spraying, there's a slight warm sensation, then completely nothing. After 30 minutes, it's in full effect, and there's no extra burning sensation during friction.
Usage steps and my actual test data
I followed the official instructions: spray 1-2 pumps directly on the coronal sulcus of the glans, spread evenly with a finger, avoid the urethral opening, and gently press to aid absorption. The first time, I sprayed 2 pumps, waited 25 minutes, and the actual duration extended from about 3 minutes to about 22 minutes. The second time, I sprayed only 1 pump, waited 30 minutes, and it lasted about 18 minutes. The third time, I sprayed 2 pumps, waited 40 minutes, and it reached about 35 minutes.
Note: Waiting time is crucial—20-30 minutes hits peak effect, with 30 minutes being optimal. If you wait too long after spraying, say over an hour, the effect diminishes. Also, absorption rates vary by individual; for the first time, it's recommended to start with 1 spray to find your right dosage—don't overdo it.
How to choose among other versions in the same series?
The 2H2D series also includes the Black Gold Edition, Gold Supreme Edition, Platinum Edition, etc. I did a side-by-side comparison. Simply put:
If you want cost-effectiveness, the Purple Gold Edition large bottle is the most worthwhile choice in the 2H2D series.
Precautions and suitable users
Although gentle, it's a concentrated essence and cannot be used in excess. Spraying too much may actually reduce sensitivity and hurt the experience. Those with sensitive skin should test on a small area first; stop immediately if redness, swelling, or itching occurs. Also, it's for external use only—if it gets into the eyes, rinse thoroughly with water right away.
This spray is suitable for men dealing with premature ejaculation, wanting to boost confidence, or seeking a natural feel. If you only want occasional prolongation, the Black Gold Edition is more convenient; if your budget allows, the Gold Supreme Edition is more refined. But if you're after a balance of effect and value, the Purple Gold Edition is the top pick.
How to choose between spray and oral products?
Delay spray is topical, acting directly on the local area, with fast onset and no systemic side effects. Oral products like Maca tablets need to be taken hours in advance, effects vary by person, and they may affect blood pressure. If you don't have cardiovascular issues, the spray is the safer option. My personal advice: use the topical spray as your main tool, and you can pair it with Black Maca daily to boost energy.
FAQ
Q: Will oral sex be affected after spraying?
A: The Purple Gold Edition is odorless and non-numbing. After 30 minutes, there's no residue on the skin, no irritation to your partner, and oral sex is unaffected.
Q: Can it cure premature ejaculation?
A: It can't cure it permanently, but it can significantly prolong ejaculation time and help rebuild confidence. Consistent use may improve psychogenic premature ejaculation.
Q: How long does one bottle last?
A: 10ml yields about 20-40 uses. At twice a week, it lasts about 2-3 months.
Summary
The Japanese Maruei Kenkyu Delay Spray Purple Gold Edition uses Chinese herbal ingredients to achieve gentle delay effects—no numbness, no alcohol—making it suitable for men who value a natural experience. The large bottle offers great value, but be mindful of usage methods and dosage. If you're still on the fence, you can start with the Gold Supreme Edition or Black Gold Edition, but in the end, you'll find that the Purple Gold Edition is the one that stays with you for the long haul.
