Let me start with some background. I'm 41 this year, working in sales, with lots of social engagements and late nights. These past two years I've clearly felt my condition declining. My first encounter with delay sprays was three years ago, and the first bottle I bought was the Japanese Black Panther Generation 3. After that I tried several brands, but after going around in circles I came back to Black Panther. Last month I saw they released Generation 4, claiming a complete upgrade, so I bought a bottle to try.

First, the packaging and appearance. The Generation 4 bottle is slightly shorter than Generation 3, and the nozzle has been improved—pressing it down is smoother than Generation 3, without the occasional sticking that Generation 3 had. The liquid is still transparent, and the smell is lighter than Generation 3. Generation 3 had a faint herbal medicine smell, while Generation 4 has almost no detectable odor.

First Use: Takes Effect in About 25 Minutes, No Numbing

The first time I used it was on a Saturday night. After showering, I sprayed it about half an hour in advance, pressing twice on the coronal sulcus area, and spread it evenly with my fingers. To be honest, there wasn't much of a sensation when applied, unlike some brands that give an obvious cooling or warming feeling.

After about 25 minutes, I started to feel it. This onset time is a bit faster than Generation 3—I remember Generation 3 generally took 30 to 40 minutes. The whole process lasted a little over 2 hours, about half an hour shorter than Generation 3.

The key point is no numbing. Previously with certain brands, including Generation 3 when used too much, there was a feeling of a layer in between, and the pleasure was diminished. Generation 4 has indeed improved in this regard—the physical sensation throughout was quite natural, not that numbed-out feeling. My wife also said she didn't notice anything was used.

Second and Third Uses: Feelings After Adjusting Dosage

The second time I tried spraying only once, wanting to see if a low dose would be enough. The result was that the onset time was about the same, but the duration shortened to about 1.5 hours. For my mild condition, 1.5 hours is actually sufficient.

The third time was after a meal—I had hot pot, which was quite oily. This time I waited about 40 minutes before feeling anything, much slower than on an empty stomach. So if you have plans for the evening, try not to eat too much oily food, or spray a bit earlier.

After three uses, I've summarized a few points:

Comparison with Generation 3 and Several Other Products

Since I've used both Generation 3 and Generation 4, I might as well compare them together.

Japanese Black Panther Generation 4 vs Generation 3

Compared with German EROS Ilus 101

I also used the EROS one for a while. Its characteristic is fast onset—about 15 minutes to feel it—but the numbing sensation is more obvious than Black Panther Generation 4. The duration is about the same for both. If you want speed, EROS works; if you care about natural sensation, Black Panther Generation 4 is better.

Compared with the Jiu Huang One

Jiu Huang takes a gentle approach, with onset taking about 30 minutes or more, and moderate duration. Its advantage is that it truly doesn't numb, but its disadvantage is that the strength is on the weaker side—for my moderate condition, it's a bit insufficient. Black Panther Generation 4 balances strength and sensation better.

A Few Things I'm Not Quite Satisfied With

First, Generation 4's duration is indeed shorter than Generation 3. I suspect the formula adjustment reduced the concentration of certain ingredients in exchange for a more natural sensation. This trade-off depends on individual needs, but for me it's slightly less than fully satisfying.

Second, although the nozzle has been improved, the bottle has no markings, making it hard to control how much is sprayed each time. Sometimes I press harder or lighter, and the amount varies. I later settled on pressing all the way down—two presses gives a relatively stable amount.

Third, in terms of price, Generation 4 is about ten percent more expensive than Generation 3. Although not outrageous, if used long-term, the cost still needs to be calculated.

Usage Instructions and Precautions

Based on my own experience and the instructions, here are a few points:

1. Use 20-30 minutes before intercourse, spray on the glans and coronal sulcus area, avoiding the urethral opening
2. For first use, spray once to see your reaction—don't start with three or four sprays
3. After spraying, gently massage with fingers to help absorption, and wait until fully absorbed before proceeding
4. Allow more time if using after a meal—oily foods can affect absorption speed
5. If you need to wash midway, it's recommended to wait at least 30 minutes for the effect to be fully absorbed

One more reminder: these products are for external use—do not take orally. If you have broken skin or a history of allergies, test on the inner wrist first.

Frequently Asked Questions

Q: What if it doesn't work after using it?

A: Several possibilities. First, the dosage may not be enough—you can appropriately increase it; second, the absorption time may not be sufficient—some people need more than 40 minutes; third, it may be due to body constitution—a small number of people don't absorb certain ingredients well and may need to use it several times to adapt.

Q: Will there be dependency?

A: The mechanism of external delay sprays is to reduce local sensitivity—they are not hormone products, and there is currently no clear evidence that they cause dependency. However, psychological dependency is possible—the feeling of unease when not using it. It's recommended to use as needed, not to rely on it every time.

Q: Can it be used together with other delay products?

A: Not recommended. Using external and oral products together makes the risks hard to control. Just choose one that suits you.

Who Is It Actually Suitable For

Suitable for: those with mild to moderate premature ejaculation who are afraid of numbing and pursue a natural sensation; those who previously used Generation 3 and found it okay but disliked the numbing; beginners trying external endurance liquids for the first time.

Not suitable for: those with severe premature ejaculation who pursue ultra-long duration; those allergic to alcohol (these products contain a little); those who completely don't want to use external products.

If you're still hesitating about which one to choose, you can check out the Black Panther Generation 4 details, or compare Black Panther Generation 3 and German EROS. I previously also wrote a Jiu Huang hands-on test, and an Indian God Oil comparison. Those interested can take a look.
