Juice Head iFlex Nixodine: 100mL vs Salts vs Disposable
Nicotine Alternative Guide • November 2026
Quick answer: Juice Head iFlex Nixodine comes in three formats at Vapor Empire. The 100mL bottle comes in 3mg or 6mg. The 30mL salts come in 30mg or 50mg and are made for pod systems, not sub-ohm devices. The iFlex Disposable holds 18mL and is rated up to 50,000 puffs. All three use Nixodine instead of conventional nicotine, but that does not make them risk-free.
What Is Juice Head iFlex Nixodine?
iFlex is Juice Head's Nixodine line. Instead of conventional nicotine, these products are formulated with Nixodine, which our product pages describe as "a nicotine alternative designed to provide a nicotine-like experience."
At Vapor Empire, iFlex comes in three formats: a 100mL e-liquid, a 30mL salt e-liquid, and a ready-to-use disposable. They share a name, but they are not interchangeable. Each one is built for a different kind of device.
Want the background on Nixodine itself, including what researchers have found so far? Our guide Seeing "Nicotine Alternative" on Vape Products? Here's What It Actually Means covers it in depth. This post focuses on the iFlex products and how to choose between them.
iFlex Nixodine at a Glance
| Format | Size | Strengths | Flavors | Made for |
|---|---|---|---|---|
| 100mL | 100mL bottle | 3mg or 6mg | 10 | Refillable tanks (typical use) |
| Salts | 30mL bottle | 30mg or 50mg | 10 | Refillable pod systems (not sub-ohm) |
| Disposable | 18mL pre-filled | Not listed | 9 | No refilling; up to 50,000 puffs |
Sizes, strengths and flavor counts are taken from our product pages. The mg numbers are the strengths listed for these Nixodine products. Don't assume they compare directly to the mg on a regular nicotine bottle.
iFlex Nixodine 100mL
The 100mL bottle is the largest format and comes in two strengths: 3mg and 6mg. Our product page doesn't name a device type, but low-strength 100mL bottles like these are typically used in refillable tank devices, which go through more liquid per puff.
It comes in 10 flavors: Apple Watermelon, Arctic Menthol, Cool Mint, Fruity Cream, Mango Strawberry, Pineapple Guava, Raspberry Lemonade, Strawberry Cream, Tobacco, and Watermelon Strawberry.
iFlex Nixodine Salts 30mL
The salts come in a 30mL bottle at 30mg or 50mg. Our product pages mark them not for use in sub-ohm devices, so they're meant for small, low-wattage refillable pod systems.
The salts come in the same 10 flavors as the 100mL line, so you can keep a favorite flavor if you move between a tank and a pod system.
iFlex Nixodine Disposable
The disposable is the no-setup option. It holds 18mL of pre-filled e-liquid and is rated up to 50,000 puffs. Puff ratings are estimates, and longer draws mean fewer real puffs.
Juice Head lists these hardware features for the iFLEX device:
- Three mesh coils: two for flavor and vapor, and a separate third coil for the cooling effect
- Adjustable ice level: turn the cooling up or down without changing the flavor coils. The box and Juice Head's flavor description also mention strength control, but Juice Head doesn't explain how that setting works.
- Adjustable airflow: a tighter or looser draw
- Rechargeable battery
- Display: shows battery life, puff count and ice level
It comes in 9 flavors: Cherry Bomb, Meta Moon, Mexico Mango, Miami Mint, Raspberry Limeade, Sour Apple, Sour Fab, Strawberry Banana, and White Peach Raspberry.

Which iFlex Format Should You Get?
- You use a refillable tank device: choose the 100mL in 3mg or 6mg.
- You use a refillable pod system: choose the 30mL Salts in 30mg or 50mg. Don't use salts in a sub-ohm device.
- You don't want to refill anything: choose the iFlex Disposable.
Shipping to California: every iFlex flavor except Tobacco is restricted from shipping to California addresses, and that includes all disposable flavors. Tobacco 100mL and Tobacco Salts can ship to California.
If you refill a pod system, the pod or coil will wear out over time. Here's when to replace your vape pod or coil.
Is "Nixodine" the Same as Nicotine-Free?
Juice Head describes the iFLEX device as nicotine-free, meaning it doesn't use conventional nicotine. That is not the same as having no active ingredient. Nixodine products are designed to give a nicotine-like experience.
Research has linked products sold under the Nixodine name to 6-methylnicotine, a lab-made compound similar in structure to nicotine. Independent research on how these products affect health is still limited, so don't assume Nixodine is safer than nicotine.
The University of Wisconsin Center for Tobacco Research and Intervention notes that the FDA has not authorized Nixodine products for sale. Our nicotine alternative guide goes through the research in more detail.
