I took a photo in front of the shelf and sent it to a friend with the caption, "What exactly is the difference between these two?" On the left was the Black Gold Edition 15ml portable spray, on the right the White Gold Edition 10ml. The price difference was a few dozen yuan, the capacity difference 5ml, and the packaging—one matte black, one bright silver-white. My friend replied bluntly: if you travel often, go with the black one; for home use, go with the white one. That answer was half right, but it didn't solve the core question—their mechanism of action and per-use cost actually differ more than you'd think.
First, the ingredients: the Black Gold Edition has two extra herbs
The ingredient list for the 2H2D Black Gold Edition endurance spray is Asarum (wild ginger), clove, honeysuckle, Cistanche, maca, and goji. The White Gold Edition contains clove extract, chive seeds, honeysuckle, water, and butylene glycol. The Black Gold Edition adds four ingredients—Asarum, Cistanche, maca, and goji—and omits chive seeds.
Asarum is commonly used in traditional herbal medicine to warm and dispel cold, and it produces a slight warming sensation when applied topically—this is one source of that "slight burning sensation" about 20 seconds after spraying. Cistanche and maca are common in men's health supplements, mainly for energy support, but in topical sprays their role leans more toward aiding penetration and modulating physical sensation rather than acting directly on nerves. Goji extract, meanwhile, focuses on skin tolerance.
The White Gold Edition formula is more streamlined. Chive seeds (jiucai zi) are a traditional warming herb, and combined with clove and honeysuckle, the overall approach is "fewer ingredients, more stability." What both share is that neither contains alcohol or anesthetic Western drug ingredients, so there's no numbness during use—this is the core difference between the 2H2D series and many traditional delay sprays.
The principle: not anesthesia, but reducing surface sensitivity
Many men using a delay spray for the first time fear most the feeling of "nothing at all." Traditional products work through local anesthetics like lidocaine—after spraying it's like being numbed, and pleasure is greatly diminished. The 2H2D Black Gold Edition takes a different path: herbal extracts act on the stratum corneum of the epidermis, gently reducing sensitivity in the coronal sulcus area of the glans without blocking nerve conduction.
In one sentence: it makes you "not want to ejaculate so quickly," rather than "unable to ejaculate." A slight burning sensation around 20 seconds is a normal signal that the ingredients are beginning to penetrate; it peaks at 20 to 30 minutes, is fully absorbed after 30 minutes, leaves no residue on the skin surface, and causes no irritation to your partner on contact.
How to use: how many sprays, how long to wait, where to apply
The steps are simpler than you'd imagine, but the details determine the effect.
First, spray 1 to 2 times onto the coronal sulcus of the glans, spread evenly with your fingers, and try to avoid the urethral opening. The shaft of the penis can be lightly covered—no need to focus spraying there.
Second, after spraying, gently press the glans with your fingers to promote absorption, and wait at least 20 minutes before intercourse. 30 minutes is the optimal window; beyond 40 minutes the effect gradually diminishes over time.
Third, for first-time use, start with 1 spray. Individual absorption varies greatly, and finding the dose that suits you is more effective than "spraying a few extra times." The product is a concentrated essence—arbitrarily increasing the dose won't make it last longer, and may instead prolong the burning sensation.
If oral sex is planned that day, don't worry—after 30 minutes the ingredients are fully absorbed, colorless and odorless, with no numbing sensation on oral contact. This is far cleaner than many oil-based delay products.
Black Gold 15ml vs White Gold 10ml: four dimensions examined separately
Capacity and portability: The Black Gold Edition is 15ml; the spray bottle is slightly longer but flatter than the White Gold Edition, taking up little space in a suit inner pocket or toiletry bag. The White Gold Edition at 10ml is shorter, suitable for keeping at home. At 1 to 2 sprays per use, the Black Gold Edition lasts about 30 to 40 uses, the White Gold Edition about 20 to 30.
Per-use cost: The Black Gold Edition typically costs a few dozen yuan more than the White Gold Edition, but calculated by number of uses, the Black Gold Edition costs about 1.5 yuan per use, the White Gold Edition about 1.8 to 2 yuan. The capacity advantage dilutes the unit price.
Sensation difference: Because the Black Gold Edition has extra Asarum and maca, the warming sensation after spraying is a bit more noticeable, though still within the "slight" range. The White Gold Edition feels fainter, almost imperceptible—suitable for people especially sensitive to burning. Neither causes numbness, but the White Gold Edition comes closer to the illusion of "having sprayed nothing at all."
Suitable scenarios: The Black Gold Edition 15ml portable spray suits business trips, travel, and dates—carrying it around isn't awkward, and the bottle has no sensitive information. The White Gold Edition 10ml suits fixed home use, or as an entry-level first try of the 2H2D series.

Three precautions that must be made clear
First, it is a topical spray and must not be ingested. Wash hands after spraying, and avoid contact with eyes.
Second, if the skin develops redness, swelling, itching, or worsening stinging, stop using immediately, rinse with clean water, and see a dermatologist if necessary. Herbal formulas do not mean zero allergy risk—before first use, you can test-spray a small area on the inner wrist and wait 20 minutes to observe the reaction.
Third, do not confuse it with oral medications. The 2H2D Black Gold Edition can moderately improve erection hardness and duration, but cannot replace oral ED medications. People with clear erectile dysfunction should consult a doctor first.
Also, counterfeit products circulate on the market. Genuine packaging has an anti-counterfeiting code—scratch it off, log on to the official website, and enter the code to verify. Spending an extra minute checking before buying is more useful than agonizing afterward.
FAQ: five things that will genuinely be asked
Q: How long after spraying can I wash it off?
A: No need to wash. It's fully absorbed after 30 minutes, with no residue on the skin. If you've sprayed too much and feel an obvious burning sensation, you can gently wipe the surface with a damp towel, but don't rub hard.
Q: Does it affect my partner?
A: After absorption, the ingredients cause no irritation to your partner, and oral sex is unaffected. But avoid direct contact with your partner's mucous membranes right after spraying, before absorption.
Q: Can I use it every day?
A: Use as needed; daily consecutive use is not recommended. Give your skin rest intervals—two to three times a week is a common frequency.
Q: Can I mix the Black Gold and White Gold Editions?
A: Mixing in the same session is not recommended. The two have overlapping ingredients but different concentrations and excipients, and mixing makes dosage impossible to judge. Finishing one bottle before switching to the other is safer.
Q: Can 15ml be taken on a plane?
A: 15ml of liquid is within carry-on limits, but putting it in a toiletry bag for checked luggage is more hassle-free. Keep the spray bottle away from high temperatures and direct sunlight.
Which one to choose: three scenarios matched directly
Frequent business trips, irregular date scenarios, wanting one bottle to last longer: choose the Black Gold portable spray. The 15ml capacity and spray design have obvious advantages in portability, and the per-use cost is lower.
First time trying the 2H2D series, sensitive to burning, mainly for home use: choose the White Gold 10ml. The formula is more streamlined, the sensation fainter, and the trial-and-error cost low.
Want both home and on-the-go options, or want to use them together: look at the combo pack. Two bottles cover different scenarios, and the price is usually better than buying separately.
If you care more about ingredient details and hands-on comparisons, the 15ml portable spray hands-on test has a more detailed breakdown.
When it comes to endurance, the product is only a tool—understanding your own sensitivity and scenario needs is the prerequisite. Choose right, and the difference between 15ml and 10ml isn't just capacity, but the composure of "just enough" every time you use it.
