Let me first give some background. I'm 38 this year, working in sales, traveling constantly for business and attending social engagements, with a chaotic schedule. In terms of married life, I've noticeably felt that my control isn't what it used to be over the past two years. I didn't take it seriously at first, but then one time my wife half-jokingly said, "Are you just tired?" That's when I started to face this issue head-on.

I previously tried oral medication, but it made me dizzy and flushed, and I had to take it an hour in advance—too much hassle. Later I switched to topical delay sprays and have used three so far: a top-selling one on Taobao, the Japanese Black Panther Generation 1, and the main subject of today's discussion, Black Panther Generation 2. I'm writing this mainly to give people who are also looking for topical endurance liquids a real reference, especially those torn between Generation 1 and Generation 2.

Why I Switched to Black Panther Generation 2

I used Generation 1 for about two months. It did work, but there were two issues I wasn't too happy with: first, after spraying, you had to wait quite a while—the official claim is 30 minutes, but in my experience it sometimes took over 40 minutes to take effect; second, there was occasional numbness. Although not severe, that "feeling like there's a layer in between" wasn't very natural.

Later I saw Generation 2, which was said to have an adjusted formula for faster onset and less numbness. The price difference wasn't much, so I bought a bottle to try. It's a 10ml size, and at my frequency of two to three times a week, it lasts a little over a month.

First Use: Timeline Record

The first time I used it was on a Friday night. About an hour after dinner, after taking a shower.

Following the instructions, I pressed the nozzle once, sprayed it on the glans and coronal sulcus area, and gently massaged with my fingers for about a minute. What came out was a transparent liquid, and the smell—well, it did have a faint herbal medicine scent, not pungent, but noticeable. The official description says "colorless and odorless," which I think isn't quite accurate—at least the "odorless" part is questionable.

About 20 minutes: No particular feeling, and I was a bit anxious inside, wondering if I'd have to wait as long as with Generation 1.

About 30 minutes: It started to kick in. Not a sudden numbness, but a mild "dulling"—sensitivity reduced, but tactile sensation still there. This state was much more natural than Generation 1.

After officially starting: Normally about 10 minutes, but this time it lasted almost 30 minutes. Even when changing positions, there wasn't that "threshold" urgency, and the sense of control really improved.

After finishing: No obvious fatigue, and cleaning was relatively convenient—just rinse with water.

Observations from Subsequent Uses

I used it five or six more times afterward, and here are a few patterns I summarized:

Onset time is related to showering. If you shower 5 minutes after spraying, the onset will be slower, about 35-40 minutes. If you don't shower and just wait, 25-30 minutes is quite noticeable. The official claim says "can shower after 5 minutes without affecting efficacy," but based on my experience, showering does slightly affect absorption.

In terms of dosage, 1 spray is enough. Once I wanted better results, so I sprayed twice, and the numbness increased significantly, reducing pleasure quite a bit. So the instruction manual's advice to "start with a small dose for first-time use" makes sense—definitely don't be greedy.

Duration is roughly between 25-40 minutes. On an empty stomach or when in good condition, it's close to 40 minutes; when tired or after drinking, it's shorter, about 25 minutes. This range is sufficient for me—after all, you're not aiming for a marathon every time.

The Downsides Must Be Mentioned

First, the herbal medicine smell issue. Although it fades after a while, the smell is definitely there for the first 20 minutes after spraying. If your partner has a sharp nose, they might ask about it. I learned to spray it half an hour in advance and wait for the smell to dissipate before entering the room.

Second, occasional warming sensation. About once every three or four uses, there's a slight warming feeling at the sprayed area—not painful but noticeable. Customer service said it's normal and varies by individual. My own experience is that it's more likely when the skin is dry; waiting a few minutes after showering and drying off before spraying helps.

Third, the bottle design is average. The nozzle sometimes gets clogged, and you have to press hard a few times to get liquid out. The 10ml bottle becomes harder to spray as you use it up—you have to tilt it.

Comparison with Generation 1 and Another Product

If you're after a natural feel and can accept a bit of herbal medicine smell, Generation 2 is the most balanced of the three. If you're particularly sensitive to smell, you might want to check out How to Choose a Delay Spray, which explains how to judge based on ingredients.

A Few Suggestions for Those Who Want to Try

Who it's suitable for: People who want to improve control but don't want to take medication; people who are concerned about numbness and want to preserve pleasure; people who can accept a slight herbal medicine smell.

Who it's not suitable for: People with particularly sensitive skin prone to allergies; people who want completely odorless; people who expect to become a "perpetual motion machine" after one spray—it only helps you last longer, not change your constitution.

A few practical tips: Spray 30 minutes in advance, and massage for a minute after spraying to promote absorption; only spray once the first time, don't be greedy; wait 5-10 minutes after spraying before showering for better absorption; if you find the smell strong, you can gently wipe the surface with a wet wipe after spraying.

One more reminder: these products are only auxiliary. If premature ejaculation is severe or persistent, it's still advisable to see a doctor. I also adjusted my schedule later—less staying up late, more exercise—and with my overall condition improved, the amount of spray I used naturally decreased.

If you're also torn about which one to choose, you can check out the 2h2d Delay Liquid Comparison Review, which explains the ingredients and suitable scenarios of several popular sprays quite clearly. As for the Black Panther series, I've used both Generation 1 and Generation 2, and Generation 2 has indeed improved, but it's not perfect. Just choose according to your needs.

Finally, about the Japanese Black Panther Endurance Liquid Generation 3 Upgrade and Japanese Black Panther Endurance Liquid Generation 4—I haven't tried them yet. From the descriptions, the packaging and formula have been adjusted again. If you've used Generation 3 or 4, feel free to share your experience.
