reports from the first wave.
From verified early-access testers.
Verified tester9/10 I could tell a difference from the start - more focused, and I wasn't getting stressed as easily. I regularly got into 2-3 hour deep work sessions without much distraction. A noticeable difference to my productivity.
Verified tester9/10 I used to pour over ingredients and formulas for a living. This syrup genuinely gives an edge to the day.
Verified tester10/10 Normally I'd look at fifteen tasks and get one or two done. With this I just ticked them off - none of that holdback of a really long day ahead.
Verified tester8/10 Being a train driver on shifts, staying focused all day is everything - this ticked all those boxes. I'd reach for it over a Red Bull or Monster.
Verified tester8/10 It rounds off the caffeine buzz into something more focused and long lasting. The sweetness is subtle and takes the edge off the bitterness.
Verified tester9/10 It takes the bitterness out and I feel more level - no peaks and troughs with energy. I add it to my morning protein coffee and can already see it being part of my routine.

cognizin® citicoline
The ProblemAttention has become a scarce resource. Most people spend the day switching between tabs, messages, meetings and emails. Something is always competing for your focus. The problem usually isn't a lack of stimulation. It's a lack of sustained attention. Coffee can make you feel awake. Staying focused on what actually matters is a different challenge.
Why It's HereCiticoline is why this formula costs what it does. It's the most expensive thing in the bottle by a distance. We could have used generic Citicoline at a fraction of the price, or used Cognizin® at 50mg so the label could carry the name without carrying the cost. We used the patented Kyowa Hakko form at 250mg, the dose used in human trials.
What Research ShowsCognizin® is one of the most studied forms of citicoline available, with human trials published in peer-reviewed journals. We're not going to tell you what those studies concluded. UK food law reserves that for a short list of authorised claims, and Citicoline isn't on it. The research is public and the links are below. Read it and draw your own conclusion.

electrolytes
The ProblemMost people blame caffeine. Almost nobody considers hydration. Picture your third or fourth coffee of the day, deep into work. Your energy and focus feel less reliable than they did that morning. Usually, more is going on than caffeine alone.
Why They're HereWe added Magnesium, Sodium and Potassium, the foundations that often get overlooked. They're not the most exciting ingredients in the formula. They're some of the most important.
What Research ShowsMagnesium contributes to electrolyte balance, normal functioning of the nervous system and normal psychological function.
Per serve: about 202mg Magnesium Bisglycinate (60.75mg elemental), 160mg Sodium, 70mg Potassium -
taste and the base
The ProblemMost functional products ask people to make a trade-off. Better ingredients. Worse experience. The result is often a product that gets used for a week, then slowly disappears into the back of a cupboard.
Our ApproachWe didn't believe performance and enjoyment had to be a trade-off. Most coffee syrups are pure sugar. Battle Syrup is built on prebiotic fibre and blue agave from Mexico instead. The fibre gives the syrup its body, the agave does the sweetening, and the salt arrives last. No artificial sweeteners.
Why It MattersConsistency compounds. The products that make the biggest impact are the ones people actually keep using, long enough for the benefits to add up. That's why we led with taste: to make Battle Syrup easy to use every day, so you get the most from it.

l-theanine
The ProblemEver finished a coffee feeling more stimulated than productive? More switched on than focused? Coffee is powerful. But for some people it comes with a trade-off: jitters, overstimulation, and a brain moving faster than you can steer it.
Why It's HereL-Theanine is the standard partner to caffeine in this category. Almost every stack includes it. Most include 100mg, because the good stuff isn't cheap. We use 200mg at 99% purity.
What We're Allowed to SayLess than we'd like. L-Theanine holds no authorised health claim in the UK, so we're limited to telling you what's in the bottle and how much. 200mg, 99% pure, in every 3-pump serve. What it's known for, you can look up.

b vitamins
The ProblemThe goal isn't just to feel switched on. It's to stay switched on. You know the feeling: you start the day sharp, then reach for another coffee a few hours later. The momentum didn't last.
Why They're HereWe included B vitamins to contribute to normal energy yielding metabolism. The goal wasn't just a stronger start to the day. It was consistency all the way through it.
What Research ShowsSeveral B vitamins contribute to normal energy-yielding metabolism, normal psychological function, and the reduction of tiredness and fatigue. They play an important role in turning food into usable energy.

asked + answered.
what does reserving commit me to?
Nothing. Reserving holds your place in Batch 001 and places no order. When production is complete you get a link to buy before anyone else, and you decide then. Delivery is 2 to 3 days from order.
who is it for?
Coffee drinkers who want their ritual to work harder. It was built for people who feel the spike and pay for it later.
does it replace my coffee?
No. Battle Syrup contains no caffeine of its own. It rides with your coffee, it does not replace it.
what is battle syrup?
A salted caramel nootropic syrup for the coffee you normally drink: 3 pumps into your first cup for sharper focus and smoother energy.
how long does a bottle last?
500ml is approximately 3 weeks at 3 pumps once daily. Heavy coffee drinkers using it in more than one cup will get through it faster.
what does it taste like?
Salted caramel, and restrained with it. You get the caramel off the steam before you taste it. The first sip is sweet without being sugary. It rides with your coffee instead of sitting on top of it, then the salt arrives on the finish. 3 pumps sweetens a standard cup about as much as any syrup would. It tastes like something a barista made, not something you added.
why £49.95?
Most of the price is the formula. Every active in Battle Syrup is the studied form at a proper dose, the kind most brands quietly shrink to protect margin. It works out at £2.50 a serve. And most of that you already spend, on the syrups, the extra afternoon coffees you buy to keep going, and a focus app. Battle Syrup just folds it into one.
what if i don't keep it up?
That is the whole point of building it into your coffee. There is no new habit to maintain, no pills to remember, no powder to mix. You already make the coffee - 3 pumps and you are done. It is the supplement you will actually keep using.
when does the batch open?
Production is not yet booked. Battle Syrup will be at least 3 months away and may take longer. Everyone holding a place in Batch 001 will be notified first when timing is confirmed, before anyone is asked to buy.
