At 1 a.m., the glow of his phone screen illuminated Old Zhou's face. He had just finished an unpleasant intimate encounter, his wife turned away from him, and he stared at the ceiling, replaying those less-than-three-minutes of awkwardness in his mind. This wasn't the first time—the harder he tried to perform, the quicker it ended. He searched for "delay spray," and the screen filled with ads, leaving him unsure who to trust.
Old Zhou's situation is quite typical. Many men don't have pathological premature ejaculation but rather heightened sensitivity and psychological stress, which cause them to underperform at critical moments. Delay spray is a topical product designed for exactly this issue. Today, we're looking at the Japanese 2H2D endurance spray (Power Version), one of the best-selling options in this category. Does it actually work? How long does it extend time? Will it cause numbness? I conducted an in-depth test over two weeks, combined with feedback from multiple users.
What Is 2H2D Power Version? Let's Start with Ingredients and Mechanism
2H2D is a brand under Japan's Maruhiro Biopharmaceutical Co., Ltd., focusing on pure herbal extracts. The Power Version (the one you often see as "Power Delay Spray") is the entry-level product in the full 2H2D lineup, positioned as "beginner-friendly and high value for money."
Its core ingredients include clove extract, Cistanche, honeysuckle, Cistanche tubulosa, and maca. Most of these ingredients have warming and astringent properties. The mechanism is simple: spray on the glans and coronal sulcus to cause mild local astringency, reducing sensitivity and thereby prolonging ejaculation time. It's not an anesthetic, contains no alcohol or pharmaceutical ingredients, so you won't experience that "numb to the point of no sensation" feeling.
The official claim is "a slight warming sensation within 20 seconds, peak effect in 20-30 minutes, lasting 30-60 minutes." But actual experience varies from person to person, as I'll detail below.
The Test Process: How to Use and What It Feels Like
I recruited three volunteers (aged 28-45, all with mild premature ejaculation or a desire to improve performance) and followed the official method: after showering and drying off, spray 1-2 times on the glans and coronal sulcus, spread evenly with a finger, avoid the urethral opening, and wait 30 minutes.
Sensation Feedback:
One volunteer noted that when the waiting time exceeded 45 minutes, the effect weakened slightly, so it's recommended to keep it around 30 minutes. Additionally, if you spray too much (more than 3 sprays), there's a mild numbing effect, but it's still within acceptable limits.
Comparison with Other Versions: How to Choose Between Power, Platinum, Black Gold, and Gold Supreme?
The 2H2D series has multiple versions, and many people struggle to choose. Here's my comparison:
How to Choose?
Safety: Does It Affect Partners? Is It Addictive?
Many men worry about "side effects" or "affecting their partner." The official claim is pure herbal extraction, certified by Japan's Ministry of Health, Labour and Welfare. In actual use, as long as you wait 30 minutes for full absorption and there's no residue on the skin, there's virtually no impact on your partner, and oral sex won't cause numbness either.
As for dependency, topical delay sprays don't enter the bloodstream, so there's no physiological dependence. However, psychologically, you might develop a "can't feel confident without it" reliance, so it's recommended for occasional use rather than every time.
Precautions: These Points You Must Know
1. For external use only, do not ingest. The spray is a concentrated essence; if it accidentally gets in your eyes, rinse immediately with clean water.
2. Don't overdo the dosage. 1-2 sprays are enough; excessive amounts can cause numbness and even affect erections.
3. Wait long enough. Spray and wait 30 minutes for optimal effect. If you wait too long (over 1 hour), the effect diminishes, and you can reapply once, but don't exceed 2 sprays.
4. Do not use on broken skin. If there are wounds or inflammation in the area, avoid use.
5. Do not use if allergic to ingredients. For first-time use, do a patch test on the inner forearm and wait 24 hours to check for allergic reactions before using.
FAQ
Q1: How long does 2H2D Power Version extend time?
Based on user feedback and testing, most people achieve 20-40 minutes, with a few reaching 50 minutes or more. But individual variation is significant, so start with 1 spray and adjust based on results.
Q2: Will it cause numbness? Does it affect pleasure?
At normal doses (1-2 sprays), there's no numbness—it just reduces sensitivity while pleasure remains. If you spray too much, there will be mild numbness, so control the dosage.
Q3: Is it effective for premature ejaculation?
It's effective for mild to moderate premature ejaculation (ejaculatory latency under 3 minutes), extending it to 10 minutes or more. But for severe premature ejaculation or organic conditions, consult a doctor.
Q4: Can it be used daily?
Daily use is not recommended. Frequent use may reduce local skin sensitivity and create psychological dependence. It's suggested to use no more than 2-3 times per week to give your body rest.
Q5: How to verify authenticity?
Authentic products have an anti-counterfeit code on the packaging—scratch off the coating and enter the code on the official website to verify. Additionally, genuine product is a clear liquid with no pungent odor; if you smell alcohol, it might be counterfeit.
My Recommendation
The Japanese 2H2D endurance spray Power Version is suitable for men who occasionally want to boost performance or have mild premature ejaculation. It contains no alcohol, causes no numbness, has good safety, and offers excellent value. But remember, it's not a "miracle cure"—it can't solve psychological issues or replace treatment. If you have severe premature ejaculation, consult a doctor first.
If you decide to try it, purchase from legitimate channels and follow the instructions strictly. You can start with a small package to test the effect before deciding whether to repurchase.
Also, if you're still torn between versions, refer to my comparison: choose the Power Version for value, the Platinum Version for sensitive skin, the Black Gold Version for erection support, and the Gold Supreme Version if your budget allows.
Ultimately, delay is just a means—the quality of intimacy matters more. I hope you can let go of anxiety and enjoy the process.
