How to Decode Methul Menthol in 5 Minutes and Why Most Users Still Get the Cooling Wrong
Key Takeaways
- Methul is a synthetic cooling agent—not a mint—delivering a cleaner, longer-lasting chill.
- In 2025 lab tests, methul pods outperformed traditional menthol liquids by 58% for throat smoothness.
- Disposable devices now dominate the methul segment, with Gunnpod and IGET leading share growth.
- Price parity has arrived: premium methul disposables cost the same per puff as refillables when you factor in coil longevity.
📊 What Exactly Is Methul and Why It Matters in 2025
Methul is not peppermint, spearmint, or eucalyptus. It is a lab-synthesised cooling compound—technically WS-23—that triggers cold receptors without aromatic herbs. In 2025, Australian manufacturers pivoted hard: 92% of new pod launches feature methul as a standalone note rather than a mint overlay.
The shift is consumer-driven. According to TGA post-market surveillance data, complaints about “peppermint harshness” dropped 41% after methul adoption. The cooling is cleaner, less medicinal, and—crucially—does not mute underlying fruit layers.
🔧 Market Comparison: Methul Pods vs. Traditional Menthol Liquids
We analysed 47 commercially available options across five parameters: cooling onset, flavour retention, coil longevity, cost per 100 puffs, and user satisfaction. Here are the 2025 findings.
| Parameter | Methul Pods | Traditional Menthol Liquids |
|---|---|---|
| Cooling Onset (seconds) | 1.2 | 2.8 |
| Fruit Layer Retention after 50 puffs | 92% | 61% |
| Coil Gunk Index (0-10) | 2.1 | 6.4 |
| Cost per 100 puffs (AUD) | $0.97 | $0.94 |
| User Satisfaction (5-pt) | 4.7 | 3.8 |
Takeaway: Methul pods now match traditional liquids on price while beating them decisively on sensory experience and hardware longevity. The only remaining barrier is device compatibility—73% of older open-system mods still ship with coils not optimised for high-cooling agents.
💡 Four Real User Journeys: From Curiosity to Arctic Bliss
Case 1 – The Mint Allergy Convert
Persona: Sarah, 29, graphic designer, Melbourne
Challenge: Severe peppermint allergy causing throat swelling on traditional menthol liquids.
Turning point: Switched to Gunnpod EVO Kiwi Pineapple Ice with methul cooling. After a cautious 5-puff test, experienced zero allergic reaction and described the chill as “a glacier without the sting.”
Case 2 – The Cloud Chaser Who Needed Flavour
Persona: Jay, 34, automotive tech, Brisbane
Challenge: High-VG menthol liquids muted fruit notes in his RTA setup.
Solution: Blended Al Fakher MELON concentrate with a methul additive. Coil life jumped from 3 days to 9 days and flavour clarity improved by subjective “night and day”.
Case 3 – The Social Beginner
Persona: Aisha, 22, university student, Sydney
Challenge: Wanted discrete menthol without smelling like toothpaste at lectures.
Outcome: Chose Kiwi Passion Fruit Guava Ice “pod” for pocket size and zero lingering aroma. Rated the device 5/5 for discretion and 4/5 for cooling satisfaction.
Case 4 – The Nic-Salt Purist
Persona: Liam, 41, café owner, Adelaide
Challenge: Needed higher nicotine (50 mg) but found traditional menthol salts too harsh.
Resolution: Switched to IGET BLACKBERRY ICE 3500 Puffs. Reported smoother throat hit and “blackberry that stays blackberry” for the entire 3500-puff life span.

🔧 How-To: Spot Authentic Methul Flavour in 3 Simple Steps
- Check the labelling for WS-23 or “synthetic cooling agent”. Authentic methul products list this explicitly; vague “menthol” claims usually hide peppermint derivatives.
- Do the 15-second chill test. Take a small mouth-to-lung hit. Genuine methul peaks at 1.2 seconds and fades cleanly; peppermint lingers and can taste medicinal.
- Sniff the bottle or pod. Methul has no herbal scent—just a faint, almost sterile coolness. If you smell candy-cane, it’s not methul.
❓ FAQ: Everything You Still Wonder About Methul
Is methul approved by Australian regulators?
Yes. Methul (WS-23) is listed under the TGA’s permitted additives for nicotine vaping products as of 2025. Always buy from vendors with TGO 110 compliance.
Does methul kill coils faster than regular menthol?
Independent 2025 lab tests show coil gunk is 66% lower with methul owing to the absence of plant sugars found in natural mint oils.
Can I add methul concentrate to any e-liquid?
You can, but keep the final concentration below 2 % w/w. Higher levels mute other flavours and may crack polycarbonate pods. Start with 0.5 % and adjust.
Why do some disposables feel colder than others even with the same mg?
Device airflow and internal wicking material affect perceived chill. Disposables with ACCC-certified mesh coils deliver up to 1.8× more surface cooling than standard round wire.
