How to Make Delay Spray at Home

Updated: July 30, 2022

As much as 36% of men suffering from premature ejaculation (PE) said that they find desensitizing products as the most effective way to treat PE. This is because a desensitizing product like a delay spray reduces sensitivity instantly and helps you last longer in bed.

But how do you make a delay spray at home?

A lot of men are concerned about the ingredients and safety of the delay sprays available on the market (here). They prefer making their own delay sprays at home, so they know what they are using and how effective it is.

We have covered the complete process to make a delay spray at home using a local anesthetic:

How to Make Delay Spray at Home Using Local Anesthetic

The FDA has approved two topical anesthetics for use in delay sprays for men: Benzocaine and lidocaine. Benzocaine is milder, available in multiple forms, and a better choice than lidocaine. We recommend using benzocaine for your DIY delay spray.

Here is why:

• Lidocaine is strong and isn’t available without a prescription.
• Benzocaine is mild and easily available without a prescription. It doesn’t have severe side effects like lidocaine.

Therefore, we strongly recommend you use benzocaine for making a delay spray at your home.  We compared both benzocaine vs. lidocaine for premature ejaculation, give this article a read before moving ahead.

Here is a list of the things you need:

1. Benzocaine (Buy here)
2. Propylene Glycol (Buy here)
3. Distilled water (Buy here)
4. Spray bottle (Buy here)
5. Measuring Pitcher (Buy here)
6. Gram scale (Buy here).

Step #1: Prepare Propylene Glycol and Benzocaine Solution

The FDA has approved 3-7.5% benzocaine in a water-soluble base to be used as a desensitizing agent to delay ejaculation. This means you need to use 3-7.5 grams of benzocaine in your homemade delay spray. We recommend creating a 3% benzocaine delay spray initially and see how it works for you and then you can gradually increase its percentage with time.

Benzocaine 3% will be a mild delay spray and will give you a nice idea of how your skin and penis respond to it.

Benzocaine isn’t soluble in water while it is freely soluble in alcohol with 1:5-8. A gram of benzocaine will completely dissolve in 5-8 ml of alcohol. The most common and safe alcohol that dissolves benzocaine is propylene glycol (PEG) according to a study. It is used widely in cosmetics and skin care products and has no side effects.

You need to dissolve benzocaine in propylene glycol in the following proportions:

1. 3 grams benzocaine
2. 70 ml propylene glycol.

Here is how to create the solution:

Use a measuring pitcher and take 70 ml propylene glycol and add it to the delay spray bottle. Take the exact 3 g of benzocaine using a gram scale and add it to the spray bottle. Close the cap of the spray bottle and shake it well to dissolve benzocaine in propylene glycol.

If you have natural and 100% pure benzocaine and propylene glycol, they will mix well, and benzocaine will be completely dissolved without any residue.

If it doesn’t, you can still use your delay spray and there is no need to worry. It will just be milder due to a lack of 100% purity.

Step #2: Add Water

You have prepared a 70 ml delay spray with 3% benzocaine. It is time to add distilled water to complete the formulation and percentage of benzocaine.

Add 30 ml distilled water to the spray bottle. Mix the solution by shaking the spray bottle.

You have a 100 ml delay spray ready for use.

Step #3: Patch Test

A patch test is essential. We strongly recommend you do it.

A patch test is used to identify substances that may cause an allergic reaction to your skin. When you use any new product on your skin, it is a good idea to first test it in a hidden area of your skin to see how it works and does it cause any reaction.

In this case, you need to try your DIY delay spray on your skin before applying it to your penis. Ideally, you should patch test numbing spray inside of your arm or on your leg.

Here is how to do it:

1. Shake the spray bottle well and use 1-3 sprays on the back of your lower leg
2. Gently rub it with your fingertips
3. Wash your hands and wait for 5-10 minutes.

Here is what you need to check:

1. Numbing effect on your leg and fingertips. If you are feeling numbness in your fingertips or legs or both, the spray works
2. Numbing intensity bypinching the sprayed area vs pinching on the other leg that’s not sprayed. Compare the pinching sensation of the two legs
3. Rash, irritation, redness, and other allergic signs. Look for all these symptoms and when they occur.

Wash your patch area after the test to remove the spray.

Step #4: Make Necessary Changes

It is time to adjust the formulation based on the results of patch testing.

If everything looks OK and the patch test yielded satisfactory results, you can skip this step and move to Step #5, but we recommend you go through this step too for additional information that you might need after a few weeks (or months).

Follow this checklist for making the necessary adjustments to your homemade genital numbing based on possible patch testing outcomes:

1. You don’t feel any numbness

The first thing to note is that the numbing effect on your fingertips and leg will be minimal and it isn’t the same as what you will feel on your penis. This is because the penis is far more sensitive (due to a high number of nerve endings located there) than any other body part (if you patch tested anywhere else).

So, a slight reduction in sensitivity either in your fingertips or leg is an indication that your DIY delay spray works.

However, if you didn’t feel any desensitization anywhere after waiting for more than 10 minutes, there are two possible reasons for it:

1. You didn’t add enough sprays during patch testing
2. The benzocaine quantity in the spray is too low for you.

The first thing you need to do, in case of no numbness, is redo the patch test and increase the number of sprays. If you sprayed 3 times in the first attempt, redo the test with 5 sprays. But don’t exceed 10 sprays in any case.

If increasing the number of sprays doesn’t work (and you still don’t feel your skin numbed), the next step is increasing the percentage of benzocaine in your DIY delay spray.

Here is how to increase benzocaine percentage:

1. Take 1 g benzocaine powder and add it to the delay spray bottle
2. Shake the bottle and redo the patch test
3. Start your patch test with 3 sprays and increase it up to 10 sprays.

If adding 1 g benzocaine still doesn’t work, add 1 g more and do patch testing again. You can top up your homemade delay spray with a maximum of 4.5 g of benzocaine (this will make its quantity 7.5% which is officially recommended by the FDA).

Do not, under any condition, add more than 7.5g (or 7.5%) benzocaine to your numbing spray.

Normally, topping up your delay spray with 1-2 g benzocaine improves numbness significantly. As soon as you get a hint of numbness in the patch test, you are good to go and stop adding more benzocaine.

For multiple patch tests, it is recommended to use different parts of your skin such as the leg, back of elbow, inside of the arm, and below the foot. For all the patch tests, use your fingertips for absorption and look for signs of numbness in your fingertips. Wash the patch area with soap after the test.

2. The numbness is too mild

If desensitizing is too mild, it is OK, and no further adjustments are needed.

Your penis is highly sensitive and a mild delay spray on any other body part will work great on your penis. You can increase its effectiveness by increasing the number of sprays.

Mild numbness on the patch area is highly recommended and is an indication that your homemade desensitizing spray is perfect.

3. The spray caused an instant or delayed allergic reaction, redness, rash, or discomfort

If you feel discomfort, redness, dryness, rash, or any allergic reaction during or after the patch test, you need not use delay spray.

The minor side effects of benzocaine include these symptoms and there isn’t anything you can do about it except not using benzocaine.

It is recommended to use a natural numbing product such as VigRX Delay Wipes that doesn’t have benzocaine and has zero side effects. Click here to check it out.

Step #5: Storage and Usage

Finally, you are ready to start using your homemade delay spray to last longer in bed and delay ejaculation.

You need to store the delay spray at room temperature (59 to 77 degrees °F) in a cool and dry place. When you have to use your numbing spray, follow these steps:

1. Apply 1-3 sprays on the penis head and shaft (increase sprays for a better experience)
2. Gently massage your penis and absorb all the spray
3. Wash your hands and penis after application
4. Wait 5-10 minutes after application so the numbing agent do its work
5. Once you feel reduced sensitivity and numbness in your penis, you are ready for intercourse.
6. Wash your penis after intercourse.

Here is a detailed procedure on how to use delay spray the right way:

Here are a few additional instructions, directions, and tips based on FDA recommendations for using your homemade benzocaine delay spray:

• Start with a single spray on your penis (even if you used 3 or more sprays during the patch testing)
• Each spray increases the intensity in terms of reduction in penis sensitivity and numbness so if you want to increase effectiveness, add more sprays
• Always wash your penis before intercourse to avoid transferring the numbness to your partner’s mouth or vagina
• Apply delay spray on penis head and shaft for better results. The penis head is the most sensitive part of your penis so make sure it is numbed completely for lasting longer in bed
• Stop using delay spray in case of rash, irritation, or itching in your penis.

How to Increase/Decrease the Intensity of DIY Delay Spray?

The response of 3% benzocaine is quite variable for different men. It might be too strong for some while 7.5% might be too mild for others. So, it is highly likely that you might have to increase or decrease the intensity of your homemade delay spray.

The intensity refers to its numbing power and effectiveness.

Here is how you can increase or decrease the numbing effect of your delay spray to suit your needs:

1. You can control the intensity with the number of sprays on your penis. A single spray has low intensity as compared to 3 sprays. Increase or decrease the number of sprays to manage numbing effectiveness
2. The percentage of benzocaine in the delay spray is directly associated with the numbing effectiveness. Start with 3% (or 3 g in 70 ml propylene glycol and 30 ml distilled water). Gradually increase the percentage of benzocaine in the solution to increase numbing intensity (stick with 1 g or 1% benzocaine). The maximum benzocaine percentage should not exceed 7.5
3. Use the process mentioned in Step #4 to adjust your DIY delay spray to suit your numbing requirements.

Homemade Delay Spray Requires Caution

Making a delay spray at home to last longer in bed might not be cost-effective, but it gives you full control over numbing effectiveness and lets you adjust intensity based on your needs.

We used scientific studies, FDA guidelines, and data from available manufacturers to create this step-by-step process to make delay spray at home. It is strongly recommended to follow the procedure discussed above.

In case of itching, redness, rash, discomfort, or any allergic reaction after the use of your homemade genital desensitizing spray, please discontinue use and consult a doctor.
