There are many types of male delay sprays on the market, and choosing the wrong one not only wastes money but may also affect the experience. This article provides a comparative review of three popular products—Wan Nai Gold Upgrade, German Black Diamond, and EROS Ilus—comparing them across five dimensions: ingredients, onset time, duration, side effects, and price, to help you quickly find the most suitable option based on your needs.
Wanai, Black Diamond, EROS: A Three-Way Comparison of Delay Sprays
The market for male delay sprays is flooded with countless brands, but only a few are truly worth your attention. This time, I’ve picked three representative products—Wanai Male Delay Spray 10ML Gold Upgrade, German Black Diamond Endurance Liquid, and German-imported EROS 101 Male Endurance Liquid—to conduct a real comparison across five dimensions: ingredients, onset time, duration, side effects, and price.
Let’s start with the core parameters:
Ingredients
Onset Time
Duration
Side Effects and Numbness
Cost per Use (Approx.)
Wanai Gold Upgrade: A Balanced Entry-Level Choice
Wanai is a product I’ve noticed with high repurchase rates across several platforms. Its ingredient list features common plant extracts like Cnidium monnieri and clove, with no alcohol, making it gentler on sensitive skin. The onset time is moderate at 15-20 minutes, so it’s best to spray about half an hour in advance. The duration of 30-60 minutes is sufficient for most men.
Advantages: Gentle formula with almost no irritation; reasonable price; precise spray nozzle design to minimize waste.
Disadvantages: Onset isn’t fast, so last-minute use reduces effectiveness; some may still experience mild numbness, though it doesn’t affect the experience.
If you’ve never used delay products before and want to dip your toes in, the Wanai Male Delay Spray 10ML Gold Upgrade is a solid choice.
German Black Diamond Endurance Liquid: The Fastest Onset
The German Black Diamond Endurance Liquid prides itself on speed—the official claim is 8 minutes, and in practice, it takes about 10 minutes to take effect. Its formula contains a bit of alcohol, which speeds up absorption, but sensitive skin might feel a slight warmth. The duration is decent at 40-90 minutes, placing it in the mid-to-upper range.
Advantages: No need for long advance preparation; works on the fly; no numbness with a cooling sensation design; affordable with the lowest cost per use.
Disadvantages: Alcohol may cause mild stinging for some users; relatively shorter duration, disappointing those seeking extended performance.
This German Black Diamond Endurance Liquid is ideal for users who often act on impulse or dislike advance preparation.
EROS 101: Oral-Grade Long-Lasting Performance
EROS 101 is the most unique of the three—it claims to be orally safe, boasts high safety, and offers the longest duration, up to 2 hours. Its ingredients are all food-grade plant extracts, with almost no numbness. Of course, the onset is slower, taking about half an hour.
Advantages: Almost no numbness, ensuring a good experience for both partners; strong endurance suitable for "marathon" sessions; oral use adds flexibility.
Disadvantages: Slow onset requires planning over half an hour in advance; highest price, with a cost of 30-40 RMB per use.
If you’re highly sensitive to numbness or need extended performance, the German-imported EROS 101 Male Endurance Liquid is worth considering.
Summary: Choose Based on Needs, Not Trends
First-time user, seeking gentleness → Wanai Gold Upgrade
Pursuing fast onset, no numbness → German Black Diamond Endurance Liquid
Focusing on ultra-long duration, zero numbness → EROS 101
One more note: Regardless of your choice, it’s recommended to start with a small amount to find the dosage that suits your body. For more insights on selecting delay sprays, you can refer to my previous article How to Choose Topical Endurance Liquids: A Comparison of 2h2d, Louis 16, and Black Panther II, and Pirelli Delay Spray: Ingredient Pharmacology and a Complete Guide to 40-Minute Delay Use.
Finally, a reminder: Topical endurance liquids are only supplementary aids. If you have long-term issues with premature ejaculation, it’s advisable to consult a doctor. Safety comes first.
常见问题
Q1.Which is more effective, Wan Nai Delay Spray or German Black Diamond?
The two products have different positioning. Wan Nai works slowly but is gentle, suitable for beginners and those sensitive to alcohol; German Black Diamond works quickly (8-10 minutes) without numbness, ideal for temporary use or those who dislike preparing in advance. In terms of effectiveness, German Black Diamond lasts slightly longer (40-90 minutes), but Wan Nai also lasts 30-60 minutes, which is sufficient for daily use. It is recommended to choose based on your personal habits.
Q2.Will using a delay spray make me completely numb?
No. Legitimate delay sprays extend ejaculation time by reducing the sensitivity of the glans, without causing complete numbness. The numbness from Wan Nai Gold Edition and EROS Yilusi 101 is very mild, while German Black Diamond causes almost no numbness. For first-time use, it is recommended to start with the smallest dose to find a balance that allows for endurance without affecting pleasure.
Q3.Is it true that EROS Yilusi 101 can be taken orally? Is it safe?
Yes, it is true. EROS Yilusi 101 uses food-grade plant ingredients, and a small oral intake will not cause harm. However, note that it is designed as a topical spray; oral intake is only for added safety (e.g., accidental ingestion after oral sex), and deliberate oral consumption is not recommended. Using it externally as directed is more standard.
Q4.Will long-term use of delay sprays lead to dependence?
Topical delay sprays are not addictive and do not cause physical dependence. However, long-term use may lead to psychological dependence, where users dare not attempt unassisted sexual activity. It is recommended to use them occasionally or combine them with exercises like Kegel exercises to gradually improve control and ultimately reduce reliance on the spray.
Q5.Which of these three sprays is suitable for people with severe premature ejaculation?
For severe premature ejaculation (ejaculation latency <1 minute), EROS Yilusi 101 is recommended as the first choice because it has the longest duration (60-120 minutes), maximizing extension. German Black Diamond is next, as it works quickly without numbness, suitable for quick adjustments. Wan Nai is suitable for mild premature ejaculation or first-time users. However, for severe premature ejaculation, you should also consult a doctor to rule out psychological or organic issues.
