In October 2024, an old friend reached out to me on WeChat, saying he wanted to try a delay spray and asked if I knew any reliable ones. At that point, I'd already been using the 2H2D Black Gold Edition for about half a year, so I just replied: give me some time to write up a summary for you.
That summary ended up being delayed for nearly two years. It's not that I didn't want to write it—it's that drawing conclusions after only a month or two felt too hasty. Now that I've been using it for 22 months, having switched to the Platinum Edition in between, tried other brands, and taken breaks, I think I can seriously talk about how the Japan 2H&2D Delay Liquid Black Gold Edition 15ML Portable Spray—the must-have men's delay bestseller—actually performs.
Let me start with the conclusion: it solved a specific problem for me, but the process wasn't smooth sailing.
The First Time I Used It, I Sprayed Twice

In March 2024, I ordered my first bottle of the Black Gold Edition from the official website. I chose the 15ml because I valued portability—I'd used a 10ml bottle before, and stuffing it into my toiletry bag during business trips always made me anxious that it was about to run out.
I tried it the night it arrived. Following the instructions, I sprayed it directly on the corona sulcus area, two sprays, and spread it evenly with my finger.
After about 20 seconds, I felt a mild burning sensation. Not a sharp pain—more like the warmth that spreads from inside out after drinking a shot of strong liquor. I panicked a bit and flipped through the manual, which said this was a normal reaction.
I waited 30 minutes and started. That night didn't go well—not because it wasn't long enough, but because it was too long, so long that even I felt exhausted. Checking the time at the end, it was about 50-something minutes.
The next day I told my friend: the effect is too intense, you need to reduce the dosage.
Going from 2 Sprays to 1 Took Me Three Months
The easiest mistake for beginners is to go by the upper limit in the instructions. The instructions say spray 1-2 times, and many people, like me, go straight to 2.
But everyone's skin type and absorption are different. I eventually developed my own routine:
This adjustment process took about three months. There were a few times I sprayed too much, and I could feel the heat throughout the entire process—not painful, but I just couldn't fully relax.
So if you're using it for the first time, my advice is: start with 1 spray. Don't be greedy.
The Non-Numbing Aspect Is the Main Reason I Stayed

I'd used another brand before, and after spraying, I couldn't feel much of anything—that "did it but felt like I didn't" experience. Although my partner appreciated the longer duration, she noticed my expression wasn't right and asked if I was uncomfortable.
The biggest difference with the 2H2D Black Gold Edition is: you still have sensation—it just pushes that threshold further back.
The ingredient list includes Asarum, Clove, Honeysuckle, Cistanche, Maca, and Goji Berry, with no alcohol or chemical irritants. From my experience, it doesn't add extra burning during friction, and after 30 minutes it's basically fully absorbed with no residue on the skin.
One detail I specifically tested: after spraying, wait 30 minutes, rinse with water, then start. The effect weakens somewhat but doesn't disappear completely. This shows it's actually absorbed by the skin to some extent, not just a surface coating.
Regarding the impact on my partner: she never mentioned any irritation. I asked, and she said there was no odor and no discomfort.
The 15ml Portable Bottle—How Long Does One Last
The official claim is that 10-15ml can be used for 20-40 times. I actually tracked it:
That works out to less than 5 yuan per use. Cheaper than a trip to the movies.
Portability is indeed the Black Gold Edition's advantage. The bottle is about a size larger than a lighter, inconspicuous in a pocket. It's never been questioned at airport security during business trips. The bottle has no sensitive information on it, which is quite important to many people.
I Switched to Another Version Midway, Then Switched Back

In early 2025, I tried the 2H2D Platinum Edition. The Platinum Edition was launched in 2020, with ingredients slightly different from the Black Gold Edition.
Personal experience: the Platinum Edition takes effect a bit slower, but the duration is more stable. The Black Gold Edition takes effect quickly, reaching its peak in 20-30 minutes, but if you wait too long—say over an hour—the effect starts to decline.
I also tried Jin Neng Delay Spray later, which is more suited for people wanting a stronger physical sensation. I ultimately went back to the Black Gold Edition for a simple reason: the balance of 15ml portability and non-numbing effect is the most suitable for me.

A Few Questions You Might Care About
Will it cause dependence?
I stopped for two months with no withdrawal symptoms. It's not an oral medication, doesn't act on the central nervous system—it just locally reduces sensitivity. When you stop, you return to your original state, not worse.
Are there side effects?
I haven't experienced redness or itching. But the instructions clearly state: if an allergic reaction occurs, stop using immediately and see a dermatologist. This is something to watch for with all topical products.
Can it cure premature ejaculation?
No. It only temporarily extends duration. If you have a long-term issue, I suggest seeing a doctor. The product itself also states it cannot replace oral therapeutic medication.
How to verify authenticity?
There's an anti-counterfeit code on the packaging—scratch it off and verify on the official website. I verified my first bottle before using it. Don't skip this step.
Advice for Different People
After using it for nearly two years, I think this product suits these people:
Not so suitable for these people:
If you decide to try it, my advice is just three points:
First, buy the 15ml Black Gold Edition portable bottle first—don't start with a large bottle.
Second, spray only 1 time the first time, wait 30 minutes, and record how you feel.
Third, if you feel the effect isn't enough, consider going to 2 sprays the next time, but don't add more in the same session.
Also, if you and your partner use it together, you might consider the combo pack, which includes lubricant—using them together improves the experience.
There are also some frequently asked questions, like what's going on when "it feels like you didn't spray anything," which you can check in this Q&A—it explains things quite clearly.
One last honest note: this type of product isn't a necessity. If your current relationship and situation are both good, you don't need it to prove anything. But if you genuinely have a need, choosing one with clear ingredients, no numbing, and dosage you can control yourself is better than blindly trying a bunch.
I use it because it helped me solve a specific problem without creating new ones. That's enough.
