Performance Caffeine

Performance Caffeine from The Protein Works™ is a premium grade, 100% pure caffeine supplement in tablet form. It’s used to address the central nervous system (CNS) and to help boost energy levels therefore enabling you to maximise absolute power output during your workout. Performance Caffeine is used by both strength and endurance athletes and is the most widely used single pre-workout ingredient in sports nutrition today based on its ability to produce a more favourable ionic environment within the working muscle.


Performance Caffeine & Sports Performance

As well helping to positively improve both the central nervous system and the environment within the working muscles, the pure caffeine content in TPW™’ Performance Caffeine has also been shown to enhance the production of certain neurotransmitters and in turn boost sports performance. Specifically researchers found as little as 200 milligrams of caffeine when taken pre workout can increase ‘strength endurance’ and reduce an athlete’s perception to fatigue and pain by stimulating the production of the neurotransmitters. Ultimately, this means TPW™ Performance Caffeine can help improve training and work output of any kind, whether strength, speed or endurance based.


Performance Caffeine & Fat Loss

TPW™’s Performance Caffeine is also commonly used by those looking to lose body fat. This is because not only does the pure caffeine content help to speed up the metabolism but it also puts the body in a state where it is better able to burn fat as a fuel supply. This coupled with the positive influence it has on neurotransmitters as previously mentioned means Performance Caffeine is the ideal supplement for those feeling lethargic and needing a little help when losing fat.

Caffeine is a powerful product so always follow the suggested usage.

Order game quickly and was well packaged, able to fit through the letter box. I use these for school/ personal studies and they are very effective.
This is a great value quality caffeine product which i have used in the past to provide an energy boost either mid-morning or mid afternoon in work to keep going, i would rather use 1 to 2 of these than drink the coffee.

They also stack well with any non-stim pump based pre-workout to provide you with the best of both the extra strength, endurance and reduced perception of exertion from the caffeine and the pump from the pre-workout.

It also helps to cycle of caffeine after 1-3 months usage for 2-4 weeks to allow for the adrenal glands to recover from being fatigued other wise tolerance builds to the product and you require a greater dose to get the same effect.

5/5 good value high quality caffeine provides a quick boost in energy and eliminates sleepiness / fatigue.

Does what it is supposed to. Easy to take and get lots of tablets for the price. Will last me a long time but will get these again when I run out. Take pre-workout with my Nitro Works and notice a difference during training -I don't tire as easily and can push through two sessions with this.
Helping to wake up, but sometimes I have headache
Bought these for my better half, and ended up taking them myself on days when I can train during the day (not after 5pm). Definite energy boost and increased endurance felt by both of us. Would recommend.
I wont take a tablet after 6pm again haha but these are very good. Description is very accurate and they definitely prevent you from feeling tired at the gym.
This definitely gives you the extra boost you need in the mornings

Usually i don't really feel too much different during the workout when i take a pre-workout supplement. This though helped me focus a lot more and saw me through some big PB lifts. I use this before a track session too and the difference is phenomenal.
