What strength can I make my Nixer longfill? Five whole-shot options from 0mg to 18mg max. UK 2026 complete strength guide.
Nixer longfills can be mixed at 0mg, 3mg, 6mg, 9mg, 12mg or 18mg using standard 18mg/10ml UK TPD nicotine shots. Recipe by strength using one 60ml longfill: 0mg = no shots plus 50ml VG base, 3mg = 1 shot plus 40ml VG, 6mg = 2 shots plus 30ml VG, 9mg = 3 shots plus 20ml VG, 12mg = 4 shots plus 10ml VG, 18mg = 5 shots and no VG base. Most UK vapers mix at 3mg or 6mg accounting for around 80% of Nixer mixing. 3mg suits sub-ohm devices plus high-volume vaping where efficient delivery means less nicotine needed. 6mg suits MTL pod systems plus former smokers transitioning to vaping. 9mg works for heavy former smokers (20+ daily) plus MTL pen-style devices. UK TPD 2016 caps finished e-liquid nicotine at 20mg/ml maximum so 18mg using 5 shots is the practical ceiling. Each 18mg shot adds 3mg/ml when diluted in 60ml. Match strength to device type plus vaping volume rather than chasing higher numbers. Easy to step down nicotine over months by mixing at progressively lower shot counts using syringes for partial-shot precision.

All strength options at a glance
Six standard strengths achievable with Nixer longfill plus 18mg nic shots. Each suits different vaping styles plus former-smoker profiles.
| Strength | Nic shots needed | VG base needed | Best for |
|---|---|---|---|
| 0mg | 0 shots | 50ml | Ex-smokers stepped down. Social vaping. |
| 3mg | 1 shot | 40ml | Sub-ohm devices. Light former smokers. Cloud chasers. |
| 6mg | 2 shots | 30ml | MTL pod systems. Moderate former smokers (10-20 daily). |
| 9mg | 3 shots | 20ml | Heavy former smokers (20+ daily). MTL pen-style devices. |
| 12mg | 4 shots | 10ml | Very heavy smokers. Niche use case. |
| 18mg | 5 shots | 0ml | Maximum legal UK strength. Specific therapeutic mixing. |
Reading the chooser table.
- Each shot adds 3mg/ml to the finished 60ml e-liquid since 10ml of 18mg diluted in 60ml gives 3mg/ml.
- Total components always equal 50ml in the mixing space. Combination of shots plus VG always sums to 50ml.
- Higher strength means less VG. 18mg uses no VG base since all 50ml of mixing space taken by 5 nic shots.
- VG affects vapour plus throat feel. Less VG means thinner liquid plus less cloud production.
- 3mg and 6mg are the practical sweet spot for most UK vapers across device types.
Each strength explained
Detailed breakdown of all five practical strength options plus the maximum 18mg ceiling. Match to your device, smoking history plus vaping volume.
Zero nicotine
For ex-smokers fully stepped down or never-smokers wanting to vape socially. Full Nixer flavour without nicotine effects. No throat hit. Useful for testing flavour profile before committing to nicotine strength.
3mg light – the popular sub-ohm choice
Most popular Nixer strength for sub-ohm devices plus high-volume vaping. Efficient nicotine delivery means less is needed. Comfortable all-day use without harshness build-up. Suits light smokers (under 10 daily) plus ex-smokers stepping down.
6mg medium – the MTL pod choice
Most popular for MTL pod systems plus former smokers transitioning to vaping. Higher per-puff satisfaction without excessive harshness. Common starting strength for new vapers replacing cigarettes. Balanced delivery suits dessert plus tobacco profiles particularly well.
9mg strong – heavy smoker transition
Suits heavy former smokers (20+ daily) plus pod system users wanting maximum satisfaction per puff. Higher throat hit plus stronger nicotine sensation. Less common than 3mg or 6mg but established user base. May feel harsh in sub-ohm devices so MTL pairs better.
18mg maximum – UK TPD ceiling
Absolute UK TPD legal maximum. Five 18mg shots in a 60ml longfill with no VG base. Loses VG benefits since base liquid replaced entirely by nicotine bottles. Niche use case for very heavy smokers transitioning to vaping where nic salts are not preferred. Significant throat hit.
Choosing your strength
Six profile-based recommendations to help you choose initial strength. Refine based on personal experience over first 1-2 weeks.
Light smoker
Under 10 cigarettes daily. Looking to switch but not heavily addicted to nicotine.
Moderate smoker
10-20 cigarettes daily. Established daily smoker wanting to quit.
Heavy smoker
20+ cigarettes daily. Higher nicotine dependence.
Stepping down
Existing vaper reducing nicotine over time. Health goal or budget reason.
Pod system user
MTL pod or pen-style device. Lower volume but higher per-puff delivery.
Cloud chaser
Sub-ohm tank user. High volume vaping with efficient delivery.
How to refine your choice.
- Start at recommended strength then evaluate after 3-5 days of normal use.
- Cravings between vapes? Step up one level (3mg to 6mg or 6mg to 9mg).
- Throat irritation or coughing? Step down one level.
- No cravings plus no harshness: you are at the right strength.
- Adjustments easy with longfill format – just remix at different shot count next bottle.
UK TPD legal context
Maximum nicotine strength is 20mg/ml
UK TPD 2016 caps finished e-liquid nicotine concentration at 20mg/ml. The practical maximum achievable using standard 18mg/10ml UK shots is 18mg/ml (5 shots in a 60ml longfill). Adding more nicotine than this is illegal under UK regulations regardless of physical capacity.
Specialist higher-strength nicotine bases exist for advanced mixers but require precise calculation plus careful handling. For standard Nixer mixing the practical maximum is 18mg using 5 shots and zero VG base.
What this means in practice.
- Most users never approach the 18mg legal maximum.
- 3mg, 6mg or 9mg suits 95%+ of UK vapers.
- If 18mg is not satisfying enough, nic salts deliver nicotine more efficiently.
- Higher concentrations available outside TPD framework but require specialist supplies plus calculation.
- UK retail nicotine supply is universally 18mg/10ml shots so calculations consistent.
Stepping down nicotine over time
One of Nixer longfill’s best features: easy nicotine reduction without buying new bottles. Perfect for gradual nicotine reduction strategy.
Typical step-down progression.
- Month 1-2: 6mg (2 shots). Standard transition strength for moderate smokers.
- Month 3-4: 4.5mg (1.5 shots). Gradual reduction. Use syringes for precision.
- Month 5-6: 3mg (1 shot). Light strength. Most users comfortable here for extended periods.
- Month 7+: 1.5mg (0.5 shots) or 0mg. Final reduction toward zero nicotine.
- Pace at your own comfort. Faster or slower than this is fine.
Tips for successful reduction.
- Keep flavour consistent during reduction. New flavours plus new strength is harder.
- Track cravings plus satisfaction in mixing notes.
- Reverse if reduction is too fast. No shame in going back up.
- Volume vaping often increases at lower strengths. Plan supply accordingly.
- Consider 0mg flavour-only vaping as final maintenance step.
Mixing partial shot strengths
For users wanting strengths between standard whole-shot levels (4.5mg, 7.5mg etc.) precise measurement is required.
Equipment needed.
- 10ml syringes (GBP 5-10 for set of 5).
- Optional: digital scales for weight-based mixing (GBP 15-25).
- Calculator or spreadsheet for non-standard ratios.
- Notebook for tracking results.
Calculation rule.
- Each ml of 18mg shot adds 0.3mg/ml to finished 60ml e-liquid.
- Target strength divided by 0.3 equals ml of nic shot needed.
- Example: 4.5mg target. 4.5 / 0.3 = 15ml of 18mg shot.
- Subtract shot ml from 50ml mixing space to get VG base needed.
- Example: 50ml – 15ml = 35ml VG for 4.5mg mix.
Common partial strengths.
- 1.5mg: 5ml shot (half shot) plus 45ml VG.
- 4.5mg: 15ml shot (1.5 shots) plus 35ml VG.
- 7.5mg: 25ml shot (2.5 shots) plus 25ml VG.
- 10.5mg: 35ml shot (3.5 shots) plus 15ml VG.
Practical approach
- 0-18mg range available using 0-5 standard 18mg/10ml UK nic shots.
- Each shot adds 3mg/ml to finished 60ml e-liquid.
- 3mg and 6mg cover 80% of mixes across UK Nixer customers.
- Match strength to device first: sub-ohm 3mg, MTL pod 6mg, MTL pen 6-9mg.
- UK TPD maximum is 20mg/ml so 18mg is practical ceiling using standard shots.
- Step-down for gradual reduction with easy partial-shot mixing using syringes.

What works for strength
vs what causes problems
Specific approaches give satisfying nicotine experience. Others cause harshness or under-delivery. Here is the side by side.
Smart strength choice
- ✓Start with recommended strength then refine 3-5 days at recommended level shows whether you need to step up or down.
- ✓Match strength to device characteristics first sub-ohm efficient delivery means lower strengths satisfy.
- ✓Use whole-shot strengths for simplicity 3mg, 6mg, 9mg cover most needs without precision equipment.
- ✓Track strength results in mixing notes personal preferences emerge over time and notes help.
- ✓Step down gradually for nicotine reduction 6mg to 4.5mg to 3mg to 1.5mg to 0mg over months.
- ✓Reverse if reduction is too fast no shame in going back up. Focus on sustainable practice.
Common mistakes
- ✗Adding more than 5 shots to one longfill exceeds UK TPD 20mg/ml maximum plus is illegal regardless of physical capacity.
- ✗Starting at 9mg or 12mg as first vaper strength harshness plus nicotine sickness risk. Start at recommended profile match.
- ✗Using 18mg max strength for sub-ohm devices dramatic harshness plus nicotine sickness from high volume vaping.
- ✗Mixing without counting shots aloud easy to lose track plus accidentally over-shoot strength.
- ✗Pursuing higher strengths to compensate for unsatisfying device often device or technique change works better.
- ✗Stepping down faster than 1 month per level rapid nicotine reduction risks falling back to smoking.
