Alpha Lion Burn2O — Stim-Free Liquid Thermogenic
Most fat burners solve the wrong problem. They stack caffeine on top of caffeine until you're wired, jittery, and still capped at one dose a day because a second one means you're awake at 2 a.m. Burn2O (also written Burn 2O, Burn 2.0, or Burn20 depending on where you're reading) skips stimulants entirely and works on the metabolic side instead — a zero-calorie liquid shot you can take alongside your pre-workout, on a rest day, or before evening cardio without touching your sleep.
What's actually in the shot
L-Carnitine — 2,000mg
Fatty acids can't cross into the mitochondria on their own. Carnitine is the shuttle that carries long-chain fats across that membrane so they can be oxidized for fuel. Without enough of it, fat gets mobilized but never fully burned. At 2,000mg, Burn2O sits at the top of the range used in research, and the liquid format gets you there in one tablespoon instead of six capsules.
Practical note most brands leave out: carnitine uptake into muscle is insulin-mediated. Taking it with a small amount of carbohydrate — or alongside a pre-workout that contains some — improves how much actually lands where you want it. Taken fully fasted, absorption is lower.
MitoBurn® (L-BAIBA) — 500mg
BAIBA is a myokine — a signaling molecule your muscles release during exercise. It's part of how training tells fat tissue to behave differently, including the shift of white adipose toward a more metabolically active, brown-like state. MitoBurn is a standardized form of that molecule, which is why it gets described as an "exercise mimetic": it delivers a signal your body would otherwise only produce by training hard.
GBB (Gamma-Butyrobetaine) — 25mg
GBB is the direct precursor your body converts into carnitine internally. So while the 2,000mg above raises circulating carnitine directly, GBB nudges your own production up alongside it. It's also the ingredient responsible for the sweat. Twenty-five milligrams is a deliberate dose — enough that most people notice the thermogenic effect within 15 to 20 minutes.
CaloriBurn GP® — 10mg
Grains of Paradise (Aframomum melegueta), standardized for 6-paradol. Studied for its effect on brown adipose tissue activation and daily energy expenditure — the "burn more at rest" half of the equation rather than the training half.
Why stim-free is the point, not a compromise
If you already take a pre-workout, you're likely at 250–400mg of caffeine before you touch a fat burner. Adding a stimulant thermogenic on top doesn't double the effect — it just moves you past the dose where caffeine stops helping and starts costing you sleep, appetite regulation, and recovery.
Burn2O is designed to layer underneath whatever you're already running. Zero caffeine means:
- Stack it with any pre-workout — no stimulant math required
- Take it in the evening — 5 p.m. gym sessions don't have to cost you sleep
- Use it on rest days — the carnitine and MitoBurn side doesn't depend on training to matter
- Run it through a full cut — no stimulant tolerance to cycle off from
How to take it
Shake well. One serving is 1 tablespoon (15ml), taken 15–30 minutes before training or first thing in the morning. You can take up to two servings per day, together or split. Thirty-one servings per bottle.
Expect to sweat more than usual — that's the GBB doing what it's dosed to do, and it typically shows up 15 to 20 minutes in. Zero calories and zero sugar, so it won't break a fast if you're training fasted.
Who this is for
Good fit: anyone already running a pre-workout who wants to add a thermogenic without more caffeine; evening trainers; people in a cut who want something they can take twice daily; anyone who hates swallowing capsules.
Not the right pick if: you want energy and focus from your fat burner — that's a stimulant product's job, and Alpha Lion's Superhuman Burn is the one built for it. Burn2O has no energy component by design.

Burn2O FAQ
Is Burn2O the same as Superhuman Burn?
No — they're different products that people mix up constantly. Superhuman Burn is a stimulant pre-workout powder with caffeine, built for energy and training intensity. Burn2O is a caffeine-free liquid shot with no energy component. Alpha Lion sells them together as a stack because they do different jobs.
Is it "Burn2O," "Burn 2.0," or "Burn20"?
Same product. The name is a water pun — Burn-two-O, like H₂O, because it's the liquid thermogenic. You'll see all three spellings across retailers.
Can I take it with my pre-workout?
Yes — that's what it's designed for. There's no caffeine or stimulant in Burn2O, so it layers on top of any pre-workout without adding to your stimulant load.
Will it break a fast?
Zero calories and zero sugar, so it won't interrupt a fast in any meaningful sense. Worth knowing: carnitine absorption into muscle improves with a small amount of carbohydrate, so fully fasted use gets somewhat less uptake than taking it with food.
Why am I sweating so much?
That's the GBB. It's a deliberate part of the formula, it shows up 15–20 minutes after your dose, and it's the most common thing people notice first.
How many can I take per day?
Up to two servings (2 tablespoons / 30ml) daily, either together or split into two doses. One bottle is 31 servings.
Do I need to cycle off it?
There's no stimulant to build tolerance to, so it doesn't require the on/off cycling a caffeine-based burner does.
