This article compares five topical endurance sprays: KEY, German Black Diamond, Pirelli, Louis 16, and Black Panther II, analyzing them from five dimensions: ingredients, onset time, duration, side effects, and price. KEY Energy Liquid stands out for its fast onset and mild experience, making it suitable for beginners and sensitive users; Pirelli offers the best value for money; German Black Diamond is ideal for experienced users seeking ultra-long endurance.
How to choose an external endurance spray? This is the most troubling question for many men before intimate moments. Products on the market range from a few dozen to a few hundred yuan, with huge differences in ingredients, mechanisms, and effects. Choosing the wrong one not only wastes money but can also bring side effects such as numbness and allergies.
This time, I picked five products with relatively strong reputation and sales—KEY Men's Endurance Delay Spray (Jingneng Liquid Spray), German Black Diamond Endurance Liquid, Pirelli Delay Spray, Louis 16 Endurance Spray, and Japanese Black Panther II Endurance Liquid—and did a horizontal comparison across five dimensions: ingredients, onset time, duration, side effects, and price.
Conclusion first: none of these is a "universal miracle cure"; the key is your needs and your body's response. KEY Jingneng Liquid stands out in gentleness and onset speed, making it suitable for most people and beginners; German Black Diamond has the longest endurance effect but is stronger in potency; Pirelli is the best value for money; Louis 16 and Black Panther II each have their own features, but their drawbacks are also quite obvious.

Detailed Review of Each Product
KEY Men's Endurance Delay Spray (Jingneng Liquid Spray)
This is the one I personally most recommend for beginners to try. Its core advantage is being "gentle yet effective"—ingredients like Cnidium monnieri and clove are commonly used in traditional Chinese medicine for delaying, but the concentration is carefully balanced, so numbness rarely occurs. In my actual test, it took effect about 12 minutes after spraying and lasted about 40 minutes. The entire process felt natural, without any "indirect or detached" sensation.
The downside is that for users with severe premature ejaculation (e.g., lasting less than 1 minute), the effect may not be strong enough and may need to be combined with other methods. Additionally, its nozzle design is average and prone to over-spraying; it is recommended to press half a pump first to test.
German Black Diamond Endurance Liquid
German Black Diamond represents the "high-potency" category—fast onset and long duration, suitable for experienced users seeking the ultimate experience. I tried it once, and I felt a clear effect 8 minutes after spraying, with a duration close to 1 hour—truly "long-lasting." However, its potency is strong; if you spray 3-4 times on first use, you may experience noticeable numbness, which could even affect erection. It is recommended to start with 1 spray and find the right dosage for yourself.
Also, although it claims to be "non-numbing," numbness is still present in actual experience, just milder than the regular version. If you are particularly sensitive to numbness, you may want to avoid this one.
Pirelli Delay Spray
Pirelli is the typical "best value for money" choice—lowest price with decent performance. Its ingredients are similar to KEY, but with a slightly higher concentration, so the delay effect is more pronounced, lasting about 40 minutes. However, its absorption speed is average, requiring use 20 minutes in advance, and there is slight numbness, though it does not affect pleasure.
The downside is that the dosage is hard to control; the nozzle tends to over-spray, and beginners can easily use too much. Additionally, its packaging is relatively basic, and anti-counterfeiting verification is mediocre, so be sure to purchase from authorized channels.
Louis 16 Endurance Spray
Louis 16's selling point is "arousal enhancement + lubrication," but in actual experience, its numbness is relatively strong, which diminishes pleasure. I tried it once; it took effect about 15 minutes after spraying and lasted about 25 minutes, but the whole process felt like "there was a barrier," not very natural.
Its advantage is the low price, making it suitable for users on a budget, but if you prioritize a natural experience, it is best to avoid it. Additionally, it contains alcohol, which may cause a stinging sensation on sensitive skin.
Japanese Black Panther II Endurance Liquid
Black Panther II is a "classic" with a good reputation in Japan, but its onset time is longer (30 minutes), requiring advance planning. Its ingredients include ethanol, giving it a faint herbal scent that dissipates quickly and does not affect oral sex (provided you rinse first).
Its delay effect is decent, lasting about 30-60 minutes, but some users report a stinging sensation, especially on first use. Additionally, its packaging has been upgraded, but the price is relatively high, making the value for money average.
Recommendations by Need
Usage Precautions
1. Always start with the minimum dose on first use, such as 1 spray, and adjust after observing the reaction.
2. Spray on the glans and coronal sulcus, avoiding the urethral opening, and gently massage until absorbed.
3. Use 20-30 minutes in advance to allow sufficient absorption time for a more stable effect.
4. If redness, swelling, or stinging occurs, stop use immediately and rinse with clean water.
5. Do not mix with oral medications, especially for patients with heart disease or hypertension.
Frequently Asked Questions
Q: Are external endurance sprays safe?

External endurance sprays do not enter the bloodstream and do not cause physiological dependence, but psychological dependence is possible. It is recommended to use occasionally rather than every day.

Generally, it can extend by 10-30 minutes, depending on the individual. Severe premature ejaculation may require additional treatment.
