IVG Nic Salt E-Liquid Pro Blue: what is in the bottle

IVG Nic Salt E-Liquid Pro Blue is a 10ml nicotine salt e-liquid from IVG, listed here in 20mg strength at £2.99 a bottle, or five for £10 when you mix and match under our nic salt multibuy. It is a bottle of liquid, not a finished device. That matters for everything on this page: you need a refillable pod kit or pod system to use it, and it is not meant for a sealed prefilled pod or a high-power sub-ohm tank.

IVG is one of the bigger names on our shelves, with nearly 400 products in the IVG collection covering kits, pods, shortfills and nic salts. Pro Blue sits in the nic salt line, alongside flavours such as Blue Ice, Blue Raspberry, Fresh Mint and Pink Lemonade. The parent IVG Nic Salt E-Liquid page lists the wider line, and if you are comparing the whole category rather than one bottle, the nicotine salt e-liquids collection is the broader shelf.

Here is the short version of what to expect. The name points at a blue fruit profile with a cool finish, the strength is the top legal figure for UK e-liquid, and the price per bottle drops to £2.00 when you buy five. The rest of this page goes through the detail so you can decide before you order, including the less glamorous parts such as who should not buy it and where it will not suit your hardware.

We do not invent figures that are not on the bottle, so you will not find a made-up puff count or battery capacity here. Where a number depends on your device, we say so and give you the arithmetic instead.

Flavour profile: what Pro Blue is aiming for

Flavour is subjective, and a label name is a guide rather than a recipe, so treat this section as direction rather than a tasting note from someone who has measured the bottle. Elsewhere in IVG's range, the Pro Blue name is used on products whose flavour tags read blueberry, raspberry and ice, and that is the sensible expectation here: a rounded blue fruit base with a cooling finish, rather than a sharp sour or a dessert-style profile.

Blue flavours in vaping tend to fall into three camps. Some lean towards blueberry, which reads as a darker, slightly jammy fruit. Some lean towards blue raspberry, the bright candy-style profile that dominates the UK market. A third group blends the two and adds a menthol or ice layer. Pro Blue appears to belong in that third group, which is also the most forgiving for someone who has not settled on a favourite yet.

The ice layer does a particular job. It adds a cooling sensation on the inhale and often on the exhale, and it takes the edge off perceived sweetness, which makes a fruity liquid easier to vape for longer sessions. That is why people who find fully sweet profiles cloying often drift towards iced blue fruit. Cooling agents differ in strength between brands and batches, so one bottle can feel cold at the back of the throat while another stays gentle.

If you want to steer the flavour in a particular direction, these neighbours in the same line are worth a look:

• Colder and cleaner: Ice Menthol drops the fruit and keeps the chill.
• Brighter and more candy-like: Blue Sour Raspberry adds a sharp edge.
• Fruit with a citrus twist: Blue Razz Lemonade brings in lemonade.
• Simpler blue: Blue and Blueberg Burst sit nearby for anyone who wants to compare.

One honest caveat: nic salt flavouring is usually tuned for a tight draw on a small device, so the flavour reads as concentrated per puff compared with a shortfill. Over a long day, even a good liquid can start to taste flat because your palate tires of it. Rotating two or three flavours is common among regular vapers, which is one reason the mix and match multibuy suits this line so well. If you like the cooling side of the profile, the wider ice e-liquids and blue raspberry e-liquids collections are the natural next stops.

Throat feel and delivery: how 20mg nic salt behaves

Nicotine salt is nicotine combined with a mild organic acid, commonly benzoic acid. The combination lets a liquid carry a higher strength without the harsh throat hit that the same amount of freebase nicotine would give. That is the main reason 20mg nic salts are so common in small pod devices: the vapour usually feels smoother at that strength than a freebase liquid would. Smoother does not mean milder in nicotine terms. A 20mg salt is the strongest nicotine e-liquid that UK rules allow, and it delivers nicotine accordingly.

In practice you draw Pro Blue the way pod users usually do: a slow, tight mouth-to-lung draw, a short pause, then an inhale. Big lungfuls are unnecessary and tend to over-deliver nicotine at this strength. The liquid is designed for devices with modest wattage, so the vapour cloud is small compared with a sub-ohm shortfill. The satisfaction comes from throat feel and flavour rather than volume.

People often ask for a puff count. A bottle of liquid has no honest puff count, because the figure depends on your device, your coil, your draw length and how often you vape. What can be stated is simple arithmetic: a 10ml bottle holds enough to fill a typical 2ml pod five times, less whatever you lose to priming and the odd spill. How long each fill lasts varies a great deal, from a single long day for a heavy user to several days for someone who vapes occasionally.

Several things change how each draw feels:

• Device power: higher wattage warms the liquid more, which increases both vapour and throat hit. At 20mg that can become uncomfortable quickly.
• Airflow: a tighter draw concentrates flavour and throat feel, while opening the airflow dilutes both.
• Coil condition: a fresh coil gives the cleanest flavour, and a tired one mutes it and adds a toasted note.
• Cooling layer: ice or menthol-style cooling adds a sensation that some people read as extra strength, even though the nicotine is unchanged.

Nicotine is addictive. If you do not already use nicotine, this is not a product to start on. The strength section below explains the lower options, and the nicotine-free e-liquids range exists for people who want flavour without nicotine at all.

Design and build: the bottle, cap and label

With a liquid, design means packaging, and in the UK that packaging is regulated. Nicotine e-liquid has to be sold in a container of no more than 10ml, with a child-resistant and tamper-evident closure, and the label carries a nicotine warning, the strength, the ingredients and batch information. Products must also be notified to the MHRA before they can be sold. IVG's bottle follows the standard format for the category: a small plastic bottle with a narrow nozzle and a child-resistant cap, typically a squeeze-and-turn or push-and-turn design.

What to check when your order arrives:

• Seal: the tamper-evident ring should be intact. If it is broken, contact us before using the bottle.
• Label: the strength should read 20mg/ml, matching what you ordered, and the flavour should read Pro Blue.
• Nozzle: thin nozzles fit most pod fill ports, but a few devices have very small ports. Check yours before you buy.
• Batch code: keep a note of it, because it is the first thing anyone will ask for if you ever need to raise an issue.

Build quality for a bottle is a question of leak resistance and consistency, and the practical points are small ones. Store it upright, wipe the nozzle after filling and screw the cap fully down. A half-closed cap in a bag is the usual source of sticky pockets. The bottle is squeezable, which helps with control, but a firm squeeze on a nearly full bottle pushes out more liquid than a small pod port can take, so squeeze gently and stop early.

Treat the contents with the respect any nicotine product deserves. Keep the bottle out of reach of children and pets, wash your hands after a spill, and wipe liquid off skin straight away. The child-resistant cap is a safeguard, not a substitute for putting the bottle somewhere high and out of sight. If you carry bottles out and about, a small zip bag adds a second line of defence against leaks and keeps everything contained.

Device pairing: battery, charging and pod size

There is no battery in a bottle of e-liquid, and we will not make up a mAh figure for it. What you can do is match the liquid to the right kind of hardware, and battery and charging are part of that choice. Nic salt at 20mg is intended for low-power devices, which in practice means small pod kits and slim pen-style systems, charged by USB.

A realistic setup for Pro Blue looks like this:

• Device type: a refillable pod kit with a fill port, a pod or tank capacity of 2ml (the UK limit) and a mesh or ceramic coil.
• Battery: pod kits in this class commonly carry anywhere from a few hundred to around a thousand mAh. More capacity means more fills per charge, though the device gets bulkier.
• Charging: most modern kits charge over USB-C. A standard 5V phone charger is fine unless the manual says otherwise, and a kit should not be left charging unattended overnight.
• Activation: most pod kits are draw-activated, with a few using a button. Draw-activated is the simpler choice for beginners because there is nothing to press.

You can browse suitable hardware in our pod kits and starter vape kits ranges, and replacement parts in the refillable vape pods collection. Always confirm that a listing says refillable before you buy. The prefilled pod kits range is a different category entirely: those pods are sealed, liquid from a bottle does not go into them, and forcing the issue can damage the pod or the device.

The same reasoning explains why the single-use disposable ban matters here. Since the UK ban on single-use disposable vapes began in June 2025, rechargeable and refillable systems have taken over, and a bottle like this is the refill half of that arrangement. Think of it as a consumable that lives alongside a reusable device for months or years.

When a device reaches the end of its life, do not put it in the household bin. Lithium batteries in general waste are a genuine fire risk in collection vehicles. Take spent devices to a recycling drop-off point, a council recycling centre, or a retailer take-back scheme. If a battery is swollen, or a device is damaged and hot to the touch, stop using it, do not charge it, and ask your local council how to dispose of it.

Coils and wicking: how the liquid treats your hardware

Coils are where e-liquid does its work and where mismatched liquid causes the most trouble. Nic salt liquids are usually thinner than the high-VG shortfills made for sub-ohm tanks, with a more balanced PG to VG ratio that wicks quickly through the small holes found in pod coils. We do not state an exact PG and VG split for Pro Blue on this page, so check the bottle label. What matters is that it is a salt-style liquid intended for pod-class coils, not a thick shortfill blend.

These are the coil types you will meet in refillable pod kits:

• Mesh coils: a flat sheet of heating mesh in place of a wire wrap. The larger surface heats evenly, which tends to give steady flavour and consistent vapour. Pod mesh coils usually sit somewhere around 0.6 to 1.2 ohm.
• Ceramic coils: a porous ceramic heating element that gives clean, stable flavour and is forgiving of thinner liquids. These often run at about 1.0 ohm or a little higher.
• Cotton-wicked wire coils: the older style, still common and cheap to replace, and well suited to nic salts.

Sweet and iced liquids build residue on any coil, because sweeteners caramelise on the heating element. Expect to change a pod coil every one to two weeks of regular use, sooner if the flavour turns flat or slightly burnt. Fresh parts are in the vape coils range. A new coil also needs priming: let the pod sit for five to ten minutes after filling so the cotton or ceramic soaks through, otherwise your first draws can give a dry hit and scorch the wick.

One mistake worth avoiding is putting nic salt into a sub-ohm coil at high wattage. A coil in the 0.15 to 0.3 ohm range driven hard produces large amounts of vapour, and at 20mg that means a harsh, strong hit and a bottle that disappears quickly. If you like big clouds, a shortfill is the right tool: the shortfill e-liquids range is built for that kind of hardware, and the Blue Raspberry Ice IVG 70/30 Shortfill E-Liquid 100ml shows what the same brand does in a larger bottle.

Finally, keep the fill level honest. Filling past the maximum line floods the airflow channel, sends liquid up the mouthpiece and shortens coil life. A fill about a millimetre below the line is a good habit, and it costs you almost nothing.

Choosing your nicotine strength

Pro Blue is listed here at 20mg, meaning 20mg of nicotine per millilitre, or 2%. That is the highest strength UK law allows in a nicotine e-liquid. Several flavours in the IVG nic salt line are available in more than one strength, so check each listing, and if 20mg is more than you want, the nic salt collection includes lower-strength options across many brands. The 20mg e-liquids page collects everything at the top strength if you want to compare like for like.

These are the common starting points, offered as practical guidance rather than medical advice:

• Heavy daily smokers switching over: adults moving away from a heavy cigarette habit often start at 20mg, because lower strengths can leave them reaching for the device constantly. Pro Blue is aimed at this group.
• Light or social smokers: 10mg is usually more comfortable. If you only want an occasional vape, 20mg can feel too sharp.
• People who have never used nicotine: not suitable for this bottle. If you want flavour without nicotine, look at the nicotine-free range instead.
• Existing vapers stepping down: moving from 20mg to 10mg over a few weeks is a common path, and the same flavour is often available in both.

Signs the strength is too high include a harsh throat hit, light-headedness or feeling queasy. If that happens, stop, drink some water, and choose a lower strength next time. Signs it is too low include chain vaping, constant top-ups and cravings returning soon after a session. Both tell you the same thing: adjust one step and reassess, rather than guessing.

Device settings change the equation as well. A higher-power device with open airflow delivers more vapour per draw, so the same 20mg liquid hits harder there than in a tight, low-power pod. If you are unsure, start with the lowest wattage your device offers and a snug airflow setting, then adjust slowly. Remember that cooling flavours, like this one, can make the throat sensation feel stronger than the number on the label suggests.

Nicotine is addictive, and no strength is risk-free to a non-user. If you have a health condition or are taking medication, follow the advice of a healthcare professional before using any nicotine product.

Who Pro Blue suits, and who should skip it

It helps to be direct about fit, because the wrong match wastes money and gives a poor experience.

Pro Blue is a sensible choice if you:

• are an adult who already uses nicotine and owns a refillable pod kit or similar low-power device;
• enjoy fruity flavours with a cool finish, and want something less sweet than a candy or dessert blend;
• want a lower running cost than prefilled pods, and do not mind filling and priming;
• like to mix and match flavours under the 5 for £10 deal rather than commit to one bottle;
• want to try a new flavour without buying a new device.

You should skip it, or choose something different, if you:

• are under 18. Sales are strictly 18+, and every order is age-verified at checkout and again on delivery. You can read how that works on our age verification page;
• do not currently use nicotine. 20mg is a strong product and is not intended for non-smokers or non-nicotine users;
• only own a sealed prefilled pod device. Refill liquid will not go into it;
• prefer large clouds and a sub-ohm tank. A shortfill suits that style far better;
• dislike cooling sensations or sweet blue fruit flavours;
• have been advised by a healthcare professional to avoid nicotine.

If your device is a sealed prefilled system and you simply like the Blue Raspberry Ice direction, the Blue Raspberry Ice IVG Air Pods is the nearest ready-to-use option from the same brand. It trades the lower running cost of a bottle for the convenience of a sealed pod. For anyone who would rather buy a flavour in bulk with a device they already own, the bottle is almost always the cheaper route over time.

The honest summary is that this is a product for experienced adult nicotine users with the right hardware. It is not a beginner product, and it is not a gateway for anyone who does not already use nicotine.

How to fill, prime and vape it

Filling a pod is simple once you have done it twice. Follow these steps in order and the common problems disappear before they start.

• 1. Check compatibility. Confirm your device is refillable and note its capacity. The UK maximum for a pod or tank is 2ml.
• 2. Prepare the pod. Remove the pod from the battery and find the fill port, usually a silicone bung or a small sliding cover on the side or base.
• 3. Fill slowly. Press the nozzle into the port and squeeze gently. Aim to stop about a millimetre below the maximum line, and avoid filling over the central airflow tube.
• 4. Close and wait. Close the port firmly. Leave the pod upright for five to ten minutes, and closer to ten if the coil is new, so the wick soaks.
• 5. Start gently. Take a couple of short, soft draws before your first proper one. The first draws can taste weak while the coil saturates.
• 6. Wipe and store. Wipe the nozzle, screw the cap fully down and store the bottle upright, away from heat and sunlight.
• 7. Refill early. Top up when about a quarter remains. Running a pod dry is the quickest way to burn a coil.

Technique matters more than people expect. Use a slow, steady mouth-to-lung draw of two to four seconds, pause, and inhale. Do not chain-vape: give the coil a few seconds between draws so the wick can refill itself. Chain-vaping overheats the wick, dulls the flavour and shortens coil life, especially with sweet liquids.

When you swap flavours, empty the old pod and let it air-dry for a short while before filling, or use a fresh pod. Mixing leftover liquid with a new flavour creates a muddy taste that nobody enjoys. Wash your hands before and after filling, and keep the bottle somewhere children cannot reach.

If you want to try a different kind of hardware, the starter vape kits range includes both refillable and sealed kits, so read each listing carefully. Look for the words refillable pod or fill port before ordering, because sealed pod kits sit in a separate category.

Troubleshooting leaks, dry hits and fading flavour

Nearly every problem with a nic salt in a refillable pod comes down to a handful of causes. This list covers the common ones and how to deal with them.

• Leaking from the airflow or base: usually overfilling, a pod not seated fully, or a cracked pod. Fill below the maximum line, press the pod firmly into the battery, and replace the pod if you see cracks.
• Gurgling or spitting: condensation or flooding. With the device off, wipe the mouthpiece and blow gently through it, then wipe away any liquid before using it again.
• Burnt taste: a dry or worn coil. Let the pod soak, stop chain-vaping and replace the coil if the taste does not clear after a refill.
• Flavour fades after a few days: either vape tongue, where your palate tires of a flavour, or residue on the coil. Rotate flavours, sip some water, and change the coil.
• Harsh throat hit: power too high, airflow too tight, or the strength is more than you need. Lower the wattage, open the airflow slightly, or step down in strength.
• Weak vapour: a low battery, a blocked airflow channel or poor contact between pod and battery. Charge it, check the airflow slots and wipe the contacts with a dry cotton bud.
• Sticky residue on the pod: a spill or condensation. Wipe it with a dry cloth, and never use water on electrical contacts.
• Liquid inside the battery section: stop using the device and do not charge it. Contact the device maker.

If the problem is with the bottle itself, such as a broken seal, a leaking cap or the wrong item, please get in touch through our contact page and include your order number and a photo. Faulty items can be returned within 30 days for a replacement or refund. For hygiene and safety reasons, we cannot accept returns on opened e-liquids that are not faulty.

Our wider FAQ page covers ordering questions, and the delivery and returns page sets out the timings in full. If you are not sure whether your problem is the liquid or the device, swap in a different flavour from the same pod: if the new flavour behaves the same way, the cause is almost certainly the coil or the device.

Value for money and the 5 for £10 maths

A single bottle of Pro Blue costs £2.99. Under the nic salt multibuy, any five bottles cost £10, which works out at £2.00 each. Five single bottles would cost £14.95, so the saving is £4.95, or about a third. Because the deal is mix and match, you do not need five Pro Blue: you can pick any five nic salts from across the shop. The 5 for £10 e-liquids collection lists every eligible bottle, and the nic salt multi-packs page gathers the multibuy options. Wider offers sit on the vape deals hub.

Here is what that means in daily terms. These are illustrations, not promises, because your habits will differ:

• Moderate user: if one 2ml fill lasts two days, a 10ml bottle lasts about ten days. That is roughly 30p a day at £2.99, or 20p a day at £2.00.
• Heavy user: if you use a fill a day, a bottle lasts about five days. That is roughly 60p a day at £2.99, or 40p a day at £2.00.
• Occasional user: a single bottle can stretch for weeks, so the single price is entirely sensible.

Compare that with prefilled pods. A sealed pod holds no more than 2ml under UK rules, so even at three for £10 you are paying at least about £1.67 per millilitre, against 20p per millilitre for a nic salt bottle at five for £10. You pay for convenience: a sealed pod includes its own coil and needs no filling, while with a bottle you add a replacement coil or refillable pod every couple of weeks. Even allowing for that, the bottle works out a good deal cheaper over a month of regular use.

One delivery point is worth noting. Standard delivery is free over £20 and costs £2.99 below that. Ten bottles on the multibuy come to exactly £20, which sits right on the threshold, so check the delivery line at checkout and add a coil or one extra bottle if it shows a charge. The delivery and returns page has the full details, including next-day delivery at £4.99 for orders placed before 4pm Monday to Friday.

Value also means getting what the label promises. All our stock is genuine and sourced through authorised UK distribution, and age checks at checkout and on delivery keep the process proper for everyone.

How Pro Blue compares with other nic salt ranges

Comparisons are only useful if they are fair, so here is where IVG sits against the other nic salt names on our shelves, using the facts we can verify. In our nicotine salt e-liquids collection, IVG has 82 listings, against 135 for Elux, 91 for Hayati and 73 for Lost Mary, with Crystal Prime and Doozy at 49 each and Bar Juice at 46. IVG is mid-sized by range, which means a focused menu rather than an endless one.

• Hayati: a much bigger menu, and its own nic salts, including the Crystal Pro Max line, also qualify for 5 for £10. If you want maximum variety, the Hayati collection offers more to choose from. On price, the multibuy puts both brands in the same place at £2.00 a bottle.
• Elux: the largest nic salt range in our catalogue. Its Elux range is the one to browse if you want to sample many profiles quickly.
• Bar Juice: a long-standing name with listings from £2.59, and a box-of-ten pack for bulk buyers. The Bar Juice 5000 10ml Nic Salts E-liquids Box of 10 is useful if you go through a lot of liquid. See the full Bar Juice collection.
• Crystal Prime and Doozy: two further ranges worth a look for flavour variety, with listings starting around £2.39 and £2.59. Browse Crystal Prime and Doozy.
• Shortfills: if you run a sub-ohm device, a shortfill from the shortfill range gives more liquid per pound, but it is a different product for different hardware.

Where does IVG do well? A single brand with a coherent menu is easy to navigate, the nic salt line sits at the standard multibuy price, and the same flavours often turn up as prefilled pods, which makes it simple to move between a sealed pod and a refillable bottle without hunting for a new taste. Where is it weaker? The menu is smaller than Elux or Hayati, so if you rotate flavours constantly you may run out of new ones sooner. The 20mg listing for Pro Blue also leaves no lower-strength option for this specific flavour, so lighter users should look elsewhere in the line.

The practical advice is to pick on flavour and hardware, not on brand loyalty. Because every nic salt in the 5 for £10 programme costs the same at the multibuy price, the sensible approach is to buy one or two Pro Blue bottles alongside two or three flavours from other ranges, find what works in your device, then reorder what you actually finish. The full e-liquids collection is the place to start if you want to browse before you decide.
