GHOST Energy
A zero-sugar energy drink from GHOST — notable for two things: fully disclosed labels, and genuine flavour licensing partnerships.
Full disclosure on an energy drink is unusual
This is GHOST's genuine differentiator, and it matters more than it sounds.
Most energy drinks list an "energy blend" with a single combined total. You see 2,000mg of something and have no way of knowing how it splits — whether the taurine is at a meaningful dose or the tyrosine is a token inclusion.
GHOST publishes every dose. Which means you can actually check:
-
Exactly how much caffeine you are drinking, to count against your day
-
Whether the theanine is at a sensible ratio to the caffeine — roughly 1:2 theanine to caffeine is the researched pairing
-
Whether anything else is at a dose that does something, rather than appearing for the label
That transparency is the reason we stock GHOST, and it is the same reason we rate NutraBio and Centurion Labz. In a category where disclosure is optional, choosing to do it says something.
On the flavour licences
GHOST works with actual confectionery and drink brands rather than approximating flavours, which is genuinely unusual in this industry.
That sounds like a marketing note, but it has a practical dimension: the drink you enjoy is the one you will choose over something with sugar in it. Palatability is a large part of whether a zero-sugar option actually displaces anything.
⚠ Energy drink or pre-workout? The difference matters
People use these interchangeably, and they should not.
| Energy drink |
Caffeine and focus ingredients |
Alertness. All-day format |
| Pre-workout |
Caffeine plus 6–8g citrulline, 3.2g beta-alanine |
Training performance |
An energy drink typically carries similar caffeine to a pre-workout, but without the performance ingredients. No meaningful citrulline for blood flow, no full beta-alanine dose for muscular endurance.
The reason is volume. A can cannot hold 8g of citrulline and 3.2g of beta-alanine alongside everything else and still be drinkable. That is a physical constraint rather than a shortcut.
So using one before training is a perfectly reasonable choice — you are getting the stimulant half. Just know what you are and are not getting, and consider a stimulant-free pump product if pumps matter to you.
⚠ The daily-use problem
This matters more with energy drinks than with any pre-workout, precisely because they are designed to be drunk casually.
Tolerance builds with regular exposure. Drink one every day and within months you need more than one to feel anything — and people escalate to two or three without particularly noticing.
- The FDA cites 400mg daily for healthy adults
- That includes coffee, tea, pre-workout and any fat burner
- An energy drink plus a pre-workout plus two coffees exceeds it comfortably
And the sleep point, which is the one that actually matters: caffeine has a long half-life, so an afternoon can is still working at bedtime. Poor sleep undermines training, recovery and fat loss more than any energy drink improves them.

What is in it
-
Caffeine — the ingredient with by far the deepest evidence, for alertness, reaction time and perceived exertion
-
L-theanine — promotes alpha wave activity and smooths caffeine's edge without reducing alertness. One of the better-supported pairings in this space
-
L-carnitine L-tartrate, in GHOST's formulas. ⚠ Worth knowing carnitine uptake into muscle is insulin-dependent, so in a zero-sugar drink it is doing considerably less than the same ingredient taken with carbohydrate — see our carnitine page
-
Taurine — despite the reputation, taurine is inhibitory rather than stimulating
-
B vitamins, which are cofactors in energy metabolism rather than energy themselves
-
NooLVL or similar, an inositol-stabilised arginine silicate studied for cognitive markers
- Zero sugar

How to drink it
-
Morning or early afternoon. Not within six hours of bed.
- As a coffee alternative.
-
Before training if you want — but add a pump product if that matters to you.
- Not alongside a pre-workout.
-
Not every day indefinitely, or tolerance takes over.
Who this is for
- Anyone who wants an alternative to coffee
- People who want to know exactly what they are drinking
- Anyone who wants energy without a full pre-workout
- People replacing sugary energy drinks or soft drinks
- Anyone who cares about flavour enough for it to determine consistency
Who this is not for
Anyone expecting pre-workout performance. There is no meaningful citrulline in a can — that is a volume constraint.
Anyone already at their caffeine limit.
Anyone drinking several a day. Tolerance escalates and sleep suffers.
Anyone training in the evening.
Anyone with high blood pressure, a heart condition or anxiety, without speaking to a doctor.
Not for anyone under 18, pregnant or nursing.
Stack it with: a stimulant-free pump product before training. Not with another stimulant.
Frequently asked questions
Why does full disclosure matter?
Most energy drinks list a combined "energy blend" total, so you cannot tell whether any ingredient is at a meaningful dose. GHOST publishes every dose, so you can check.
Can I use it as a pre-workout?
You get the stimulant half only. A can cannot physically hold 8g of citrulline and 3.2g of beta-alanine and remain drinkable.
Does the carnitine do anything?
Less than you might hope. Carnitine uptake into muscle is insulin-dependent, so in a zero-sugar drink it is doing considerably less than the same ingredient taken with carbohydrate.
What does theanine do?
It promotes alpha wave activity and smooths caffeine's edge without reducing alertness. The researched ratio is roughly 1:2 theanine to caffeine.
Is taurine a stimulant?
No. Despite the reputation, taurine is inhibitory rather than stimulating.
How much caffeine is in it?
Check the can — and because the label is fully disclosed, that number is straightforward to find.
Can I drink one every day?
Tolerance builds. Better used deliberately than by default.
Will it affect my sleep?
Caffeine has a long half-life, so an afternoon can is still working at bedtime.
