This article compares three topical delay products—KEY Men's Delay Spray, German Black Diamond, and Indian God Oil—analyzing them from five dimensions: ingredients, onset time, duration, numbness, and price. KEY is suitable for those seeking pleasure, German Black Diamond for those who fear numbness, and Indian God Oil for those on a budget.
Topical endurance sprays are one of the most direct ways to address premature ejaculation, but the market is flooded with products ranging from tens to hundreds of yuan. How do you choose? Today, I'll compare three representative products: KEY Men's Endurance Delay Spray (2019 New Packaging), German Black Diamond Endurance Liquid (Hong Kong Version), and the original imported Indian God Oil GOD OIL (2nd Generation). Additionally, I'll briefly mention the German imported EROS Yilusi 101 as a supplementary reference. The evaluation will cover ingredients, onset time, duration, numbness, and price.
Let's first discuss the basic principles of these products. Topical endurance sprays primarily rely on two types of ingredients: one is plant extracts (such as clove, cnidium, and sophora flavescens), which slightly numb the glans to reduce sensitivity; the other is Western medicinal ingredients (like lidocaine), which directly block nerve signal transmission. The advantage of plant-based types is fewer side effects and no numbness, but they work slowly and effects vary by individual. The advantage of Western medicinal types is fast onset and stable effects, but they may come with noticeable numbness and even affect erections.
KEY Men's Endurance Delay Spray (2019 New Packaging)
This is the 2019 updated version from the KEY brand, a topical endurance spray that emphasizes fast onset. I've used it a few times myself, so here are my honest thoughts.
Ingredients: The official list doesn't detail specific ingredients, but based on product descriptions and user feedback, it's likely primarily plant extracts like clove and cnidium, without Western medicinal anesthetics. This is reassuring, especially for those concerned about potential harm to the body.
Onset Time: Effects are noticeable about 5-10 minutes after spraying, which is more convenient than products requiring half an hour of preparation. It offers flexibility, usable even on a whim.
Duration: One spray lasts about 20-30 minutes, not exceptionally long, but sufficient for normal sexual activity. If needed, you can reapply sparingly, but avoid overuse.
Numbness: Almost no numbness—this is its biggest advantage. After spraying, the glans only feels slightly warm, without the sensation of wearing a thick condom, and partner feedback is positive. However, spraying too much may slightly reduce pleasure.
Price: Reference price 80-120 yuan per bottle (10ml). With about 2 sprays per use, it lasts 15-20 times, costing 5-8 yuan per use—good value for money.
Advantages: Fast onset, no numbness, doesn't affect partner experience; meets the demand for "delay without numbness."
Disadvantages: Short duration, unsuitable for users needing prolonged sessions; unclear ingredient transparency; some may have allergic reactions to plant components.
Suitable for: Those seeking a natural feel, no numbness, and sexual activity lasting within 10-20 minutes.
German Black Diamond Endurance Liquid (Hong Kong Version)
This product from Germany is reportedly produced at the West German Wader Pharmaceutical Factory and has a certain reputation locally. I had a friend buy a bottle for me, and overall, it's decent.
Ingredients: No clear ingredient list, but it's said to be plant extracts with a small amount of Western medicine. Based on actual experience, it likely contains some anesthetic, as there's a slight numbness after spraying.
Onset Time: Officially claims 8 minutes, but in practice, it took about 10-15 minutes—slower than KEY but still relatively fast. Some preparation is needed.
Duration: One spray lasts 30-40 minutes, longer than KEY. With 4 sprays (the official maximum recommendation), it can exceed 40 minutes, but numbness becomes more pronounced.
Numbness: Moderate numbness; you can clearly feel reduced glans sensitivity, but it's within acceptable limits. First-time users might find it uncomfortable.
Price: Reference price 60-90 yuan per bottle (10ml), costing 4-6 yuan per use—quite affordable.
Advantages: Good duration, affordable price; effective for moderate premature ejaculation.
Disadvantages: Numbness may affect both partners' experience; dosage requires trial and error; overuse can be uncomfortable.

Original Imported Indian God Oil GOD OIL (2nd Generation)
The name Indian God Oil is familiar to many, but the market is rife with counterfeits, often bottled by small domestic factories. The one I used is the original imported new packaging version, claiming to be "numbness-free."
Ingredients: Again, no detailed ingredient list is disclosed, but it's advertised as pure plant extracts without Western medicine. Actual use showed no significant numbness, but there was a cooling sensation, like mint. It likely contains menthol, borneol, or similar substances.
Onset Time: Effects appear about 15-20 minutes after spraying, slower than the previous two. Requires advance planning, not suitable for last-minute use.
Duration: Lasts about 25-35 minutes, between KEY and Black Diamond. Effects are relatively stable but vary greatly by individual.
Numbness: Almost no numbness, but the cooling sensation is strong; first-time users might find it slightly irritating. Pre-washing can reduce the cooling effect.
Price: Reference price 50-80 yuan per bottle (10ml), costing 4-6 yuan per use, similar to Black Diamond.
Advantages: Low price, no numbness, suitable for budget-conscious users.
Disadvantages: Slow onset; cooling sensation affects experience; many counterfeits require careful identification; effects less stable than the other two.

German Imported EROS Yilusi 101 Men's Endurance Liquid
Although I haven't used this product, it's reportedly popular among users. Briefly: It emphasizes ultra-long endurance, claiming 40-60 minutes, but contains Western medicinal ingredients, leading to relatively noticeable numbness. Price is 100-150 yuan per bottle, costing 5-8 yuan per use.

Recommendations by Scenario
A final reminder: Topical endurance sprays are just aids—don't rely on them. If premature ejaculation persists, consult a doctor to check for underlying causes like prostatitis or psychological factors. Health is paramount.
help常見問題
Q1.Does KEY Men's Long-Lasting Delay Spray have any side effects?
KEY primarily uses plant extracts, with almost no systemic side effects under normal use. However, a small number of people may be allergic to its ingredients (such as clove or cnidium), experiencing mild redness, swelling, or itching. It is recommended to first test it on the inner arm to confirm no allergy before applying it to the genitals. Do not use too much; 1-2 sprays each time is sufficient.
Q2.Which is better, German Black Diamond Delay Liquid or KEY?
There is no absolute good or bad; it depends on your needs. KEY works quickly and does not cause numbness, but its duration is short. Black Diamond has a longer duration but causes numbness. If you want a delay of over 30 minutes and don't mind some numbness, choose Black Diamond. If you prioritize a natural feel and don't want to affect the experience for both parties, choose KEY. Prices are similar.
Q3.How to distinguish genuine from fake Indian GOD OIL second generation?
The genuine GOD OIL second generation packaging has an anti-counterfeiting code that can be scanned for verification. The genuine liquid is light yellow with a herbal scent and no pungent alcohol smell. When purchasing, choose reputable stores and avoid bargains. If the price is below 40 yuan, it is likely fake. Additionally, the genuine product takes 15-20 minutes to take effect; if it works immediately upon spraying, it may contain pharmaceutical additives.
Q4.Can external delay liquid be used every day?
It is not recommended for daily use. External delay liquids work by numbing the glans to reduce sensitivity. Long-term use may lead to local nerve tolerance in the glans, reduced effectiveness, and even slight atrophy. It is best to use as needed, no more than 2-3 times per week. If daily use is necessary, it is advisable to check for underlying medical conditions.
Q5.Can external delay liquids affect fertility?
Currently, there is no clear evidence that external delay liquids cause infertility. However, some products containing anesthetic ingredients (such as lidocaine) may affect sperm motility. If you are planning for pregnancy, it is recommended to use them cautiously, preferably choosing products with pure plant ingredients and no pharmaceuticals, such as KEY or Indian GOD OIL, and to clean thoroughly before intercourse.
