Recently, many of my followers have been asking me how to choose a delay spray, especially the differences between the Japanese 2H2D Black Gold Edition Long-Lasting Spray, Indian God Oil, and Green Knight. Having used them myself for over half a year and tried four different types, I'm here to share my real experiences today. No hype, no bias, just helping you save some money.

Let me start with the conclusion: There's no perfect spray, only one that suits you. If you fear numbness or worry about affecting oral sensation, prioritize the Japanese 2H2D Black Gold Edition; if you're on a tight budget and don't mind an alcohol feel, Indian God Oil can work; if you want quick results and can tolerate a burning sensation, consider German Black Diamond. I'll go through each one below.

Basic Information on Four Delay Sprays

Japanese 2H2D Black Gold Edition Long-Lasting Spray: Produced by Japan Maru Ei, recommended by Watsons. Ingredients include Asarum, Clove, Honeysuckle, Cistanche, Maca, Goji Berry, and other pure plant extracts, alcohol-free. Comes with a complimentary travel-sized pack.

Indian God Oil Climax: Original imported product, ingredients not clearly disclosed, common alcohol solvent, fast-acting.

Green Knight II Long-Lasting Liquid: Hong Kong brand, primarily plant-based ingredients, gentle and non-numbing.

German Black Diamond Long-Lasting Liquid: Manufactured by West German Wader Pharmaceuticals, contains ethanol and other ingredients, extremely fast-acting.

Core Dimension Comparison

Ingredients and Safety

2H2D Black Gold Edition: Pure plant formula, clearly labeled ingredients, no alcohol, no anesthetics. Clinically tested tens of thousands of times, relatively high safety. Drawback: Some first-time users may experience a slight burning sensation, but it disappears after 10 minutes.

Indian God Oil Climax: Ingredients are opaque, mostly alcohol and menthol, with strong irritation. Long-term use may damage mucous membranes.

Green Knight II: Primarily plant extracts, but specific ingredients not disclosed. Moderate gentleness, some users report slight numbness.

German Black Diamond: Contains ethanol and preservatives, fast-acting but highly irritating, not suitable for sensitive skin.

Onset Time and Usage Method

2H2D Black Gold Edition: Reaches optimal state 20-30 minutes after spraying. Usage: Spray on the glans corona before intercourse, apply evenly, then rinse or proceed after 20 minutes. Advantage: Fully absorbed after 30 minutes, no impact on oral sex.

Indian God Oil Climax: Takes effect 10-15 minutes after spraying, but alcohol evaporates quickly, requiring advance use. Needs rinsing before oral sex, otherwise bitter taste.

Green Knight II: Takes effect around 20 minutes, requires advance planning. Some users say it needs two or more applications for stability.

German Black Diamond: Takes effect 8-10 minutes after spraying, almost no waiting time. But strong burning sensation may be uncomfortable for beginners.

Duration and Effect

2H2D Black Gold Edition: Extends by an average of 30-60 minutes, varies by individual. I tested about 40 minutes, with improved hardness, no numbness throughout, and normal ejaculation pleasure.

Indian God Oil Climax: Extends by 20-40 minutes, but effects are unstable, sometimes causing skin damage due to alcohol allergy.

Green Knight II: Extends by 20-50 minutes, mild numbness, but effect diminishes on second use.

German Black Diamond: Extends by 30-45 minutes, but glans feels noticeably thicker, reducing pleasure.

Side Effects and Discomfort

2H2D Black Gold Edition: Almost no side effects, a few users may experience slight stinging on first use (disappears after 1-2 uses), no numbness, no redness.

Indian God Oil Climax: Common burning and stinging, some develop rashes. Long-term use may lead to decreased sensitivity.

Green Knight II: Occasional numbness, does not affect erection, but partner may taste bitterness during oral sex.

German Black Diamond: Strong burning sensation, many find it unbearable, and over-spraying can lead to prolonged duration or even inability to ejaculate.

Price and Value for Money

2H2D Black Gold Edition: Approximately 40-60 RMB per use (based on 2 sprays), higher price but stable quality. Comes with a travel pack, suitable for users seeking experience.

Indian God Oil Climax: Approximately 10-20 RMB per use, cheapest, but variable quality, many counterfeits.

Green Knight II: Approximately 30-50 RMB per use, moderate value for money, effects justify the price.

German Black Diamond: Approximately 25-40 RMB per use, cheap but irritating, suitable for tolerant users.

Detailed Experience with Each Product

Japanese 2H2D Black Gold Edition Long-Lasting Spray

This is my current go-to. I sprayed twice on first use (official recommendation is 1-2 sprays), felt a warm sensation after 20 minutes, no numbness. In practice, sensitivity decreased by about 40%, but all pleasure was present, and ejaculation was normal. Longest session lasted 50 minutes (normally 10 minutes). Advantage: Colorless and odorless, no impact on oral sex, partner completely unaware. Drawback: Requires 30 minutes advance preparation, not suitable for spontaneous moments. Also, the price is high; a 15ml bottle lasts about 15-20 uses, costing over 40 RMB per use. But considering safety and effect, I think it's worth it.

Indian God Oil Climax

First used from a friend, it felt fiery hot like applying tiger balm. After 10 minutes, numbness set in, glans felt like there was a layer. It had an effect, extending to about 25 minutes, but ejaculation sensation was weak, like being forcibly interrupted. Second time, I bought from a different source, got a counterfeit, completely ineffective. Summary: Cheap, but quality unstable, strong irritation, not recommended for beginners. If you must use it, buy a version with anti-counterfeit features, and always use it 30 minutes in advance and rinse.

Green Knight II

Green Knight has a good reputation; I bought the new premium version. Ingredients are marketed as gentle, and in practice, it was indeed more comfortable than Indian God Oil, with no obvious burning. Onset time about 25 minutes, effect lasting about 35 minutes, erection hardness improved. But there's a problem: Second use (two days apart) had diminished effect, possibly due to tolerance. Also, over-spraying causes slight numbness, requiring dose control. Suitable for those who have never used sprays and want to try.

German Black Diamond

Recommended by a friend as the fastest-acting. I sprayed three times (max four), felt heat after 8 minutes, then strong burning on the glans lasting 10 minutes. In practice, the glans felt severely numb, like wearing two condoms. Duration was indeed long, over 40 minutes, but I had no desire for a second round. Also, the glans turned red afterward, only fading the next day. Recommended only for experienced users, with a maximum of two sprays per use.

Recommendations by Scenario

First-time user, afraid of side effects: Choose Japanese 2H2D Black Gold Edition Long-Lasting Spray, gentle and safe, though expensive, the trial cost is low. Pair with 2H2D Black Maca 120 Capsules Delay and Hardness Enhancement Maca Tablets for internal and external use for more stable effects.

Limited budget, occasional emergency: Indian God Oil Climax, but buy from legitimate channels and do a patch test first.

Pursuing speed, not minding irritation: German Black Diamond, fastest-acting, but control dosage.

Wanting balance between price and experience: Green Knight II, moderate value for money, suitable for daily use.

Additionally, if you want to try gel types, check out Japanese Beilitin Men's Long-Lasting Gel 2H2D Delay Liquid Adult Products Male Delay Spray, which offers better dose control than spray and is equally gentle.

Final reminder: All delay products are aids, don't over-rely on them. If you have long-term premature ejaculation, it's recommended to see a urologist at a tertiary hospital rather than buying blindly. I previously wrote First Time Buying Indian God Oil Galatol?
