Product Uses
Recommended Usage

Consume 1 shot 30 minutes before exercise for high intensity, short duration events to ensure the body starts with elevated caffeine levels. In longer duration events consume no more than 2 shots per day. Ensure you keep hydrated. This product is not intended for children, under 16's or pregnant women. Where hydration is important, SiS GO Caffeine Shot can also be consumed with SiS GO Hydro or GO Electrolyte to ensure a combination of energy, caffeine and fluid delivery during exercise.


SiS's advanced Caffeine Shot provides 150mg of caffeine, which is sufficient to improve specific aspects of mental and physical performance, while Citrulline Malate is increasingly requested by top-level athletes.

Magnesium is included to help maintain normal muscle and nerve function and the addition of vitamins B6, B9 and B12 help reduce tiredness and fatigue. This is exactly what's needed for concentration and focus, which is particularly important when you are pushing to the limit.

The GO Caffeine shot will help you get the most from every training session and perform at your best in games. It can take 30-60 minutes after consumption for caffeine levels to peak in the blood, so consume pre training or match-play or at half-time.

The GO Caffeine shot is ideal to help you prepare for a workout or tough match.

When do I use the caffeine shot ?

Use the caffeine shot 30-60 minutes before playing football or at half time during a match for a rapid surge of energy.

How quickly does the caffeine shot work?

Research shows the caffeine used in SiS products is very fast acting, it will take approximatley 30-60 minutes before it has a desired effect.

What kind of benefits can I expect?

After taking the Caffeine Shot you'll soon feel improved concentration and alertness. You'll be ready to tackle hard sessions and perform at your best, no matter what time of day you're training.

Can I add the shot to GO Energy or GO Electrolyte drinks?

Yes - the SiS GO Caffeine Shot can be added to GO Energy or GO Electrolyte drinks so that you get the benefits of both products.

How many shots can I take each day?

The SiS GO Caffeine Shot contains high strength ingredients, so you should take a maximum of 2 Caffeine Shots per day. They are so effective there really is no need to take more! For shorter workouts you only need one shot 30 minutes before exercise, as the effects last for several hours. For endurance events, it can be beneficial to have a second caffeine shot during the event.

Why is Magnesium included?

The SiS GO Caffeine Shot includes Magnesium as this contributes to normal functioning of muscles and nerves, so is essential for attaining top performance. Scientific research shows magnesium is lost in sweat and that many athletes struggle to maintain optimal body magnesium stores during training.

Is it legal for drug tested athletes to take caffeine?

Yes. Caffeine is permitted in all sports and is not on the WADA banned list.

What is Citrulline Malate and how can it benefit me?

Citrulline is an amino acid which delays the onset of fatigue during intense exercise. For example Suzuki and co-workers gave 2.4g of L-citrulline (equivalent to 4.3g of Citrulline Malate) to cyclists and found that during a time trial speed and power were significantly increased. In addition, feelings of muscle fatigue and concentration were improved after exercise.

Tasty product that gets me up for training on those days when motivation is a little below 100%!! It also seems to increase my drive - even on 'going' days:-).

Quick and easy to take with you when you need a quick wake up, or if your favourite coffee take away outlet is closed. Small enough to just pop one in your pocket or bag for when needed. I carry one with me on my way to work.

John Warburton

Works for me when I'm a bit tired!


Excellent, but preferred the citrus variety.


Really helps with long and hard interval training. It takes about 30mins to kick in but they do seem to help me push through and complete the training session

Gives a much needed boost in the closing stages of a race.


Not entirely a satisfactory way to deliver fuel during cycling but I do find them emminently suitable during weights. Easy to down and a lovely kick! Even gave one to a female friend. Never stopped talking about it.
