What's actually in a Geek Bar? Every Geek Bar device — Pulse, Pulse X, Meloso, Skyview, Slimor — uses the same base e-liquid formulation with four core ingredients: vegetable glycerin (VG), propylene glycol (PG), nicotine salt, and food-grade flavorings. This page breaks down each ingredient, what it does, and how the formulation differs between standard and zero-nicotine devices.
Core Ingredients — All Geek Bar Devices
| Ingredient | Role | Approx. Ratio |
|---|---|---|
| Vegetable Glycerin (VG) | Vapor production — creates visible clouds | ~50–60% |
| Propylene Glycol (PG) | Flavor carrier + throat sensation | ~30–40% |
| Nicotine Salt | Nicotine delivery (addictive substance) | 5% (50 mg/mL) |
| Food-Grade Flavorings | Flavor profile (proprietary blends) | ~5–10% |
Ingredient Deep Dive
Vegetable Glycerin (VG)
What it is: A clear, odorless, slightly sweet liquid derived from vegetable oils (typically palm, soy, or coconut). What it does: VG is the primary vapor-producing ingredient. Higher VG ratios produce thicker, denser clouds. It also adds a mild sweetness to the overall flavor profile. Other uses: Widely used in food manufacturing, cosmetics, and pharmaceuticals. Classified as GRAS (Generally Recognized as Safe) by the FDA for oral consumption.
Propylene Glycol (PG)
What it is: A synthetic, colorless liquid with a faintly sweet taste. What it does: PG carries the flavor compounds and provides the "throat hit" sensation that users feel when inhaling. Higher PG ratios create a stronger throat sensation and better flavor delivery but less visible vapor. Other uses: Used in food coloring, flavor extracts, medicines, and fog machines. Also FDA GRAS-classified for ingestion. Note: a small percentage of people have PG sensitivity — if you experience irritation, consult a physician.
Nicotine Salt
What it is: Nicotine combined with an organic acid (typically benzoic acid) to form a salt compound. What it does: Nicotine salt is absorbed faster and more smoothly than freebase nicotine, allowing higher concentrations (50 mg/mL) without harsh throat irritation. Standard Geek Bar: 5% (50 mg/mL). Zero Nicotine Edition: 0% (0 mg/mL) — nicotine is completely absent from the formulation. Important: Nicotine is an addictive substance regardless of its form.
Food-Grade Flavorings
What they are: Proprietary blends of flavoring compounds used in food manufacturing. Each Geek Bar flavor (Miami Mint, Meta Moon, Blue Razz Ice, etc.) uses a unique combination of these compounds. What they do: Create the distinct taste profiles — fruit, mint, candy, sour, dessert, etc. Geek Bar uses over 103 different flavor formulations across its product line. Note: The specific compounds in each flavor blend are proprietary and not individually disclosed by Geekvape, consistent with industry practice.
Standard (5%) vs. Zero Nicotine (0%) Formulation
| Component | Standard (5%) | Zero Nic (0%) |
|---|---|---|
| VG | ✅ Present | ✅ Present |
| PG | ✅ Present | ✅ Present |
| Nicotine Salt | ✅ 50 mg/mL | ❌ 0 mg/mL |
| Flavorings | ✅ Present | ✅ Present (same formulas) |
| Benzoic Acid | ✅ (used to form nic salt) | ❌ Not needed |
The zero-nicotine version uses the same VG, PG, and flavoring compounds — the only difference is the removal of nicotine salt and its associated benzoic acid. This results in a smoother throat hit but identical flavor and vapor production. For the full zero-nic lineup, see Geek Bar No Nicotine.
What Geek Bar Does NOT Contain
| THC | Zero. Geek Bar devices contain no THC, CBD, or any cannabis-derived compounds. |
| Vitamin E Acetate | Not present. Vitamin E acetate was linked to EVALI cases in 2019 — it is not used in Geek Bar products. |
| Diacetyl | Not used. Diacetyl (linked to "popcorn lung" concerns) has been removed from major e-liquid manufacturers' formulations. |
