I want to push through my plateau…

Sounds like it's time to kick it up a gear or two.

Your training has been going great and you've been making progress. Then all of a sudden, you feel like you've hit a plateau and your progress has levelled off. When that happens, you need an extra push so you can take it up a notch and continue your progression. 

Meet The Power Booster. Creatine monohydrate is the most researched sport supplement on the market, recommended for athletes and recreational gym goers alike. Creatine is stored within muscle and plays a crucial role in the production of energy during high intensity exercise such as sprinting or weight-lifting, helping you break through your plateau to get to the next level.

How should I take it to see optimal results?

Studies have shown that a creatine loading phase where you double the daily dosage for a period of a week before reverting to the standard daily recommended dose could help maximise its effects so you notice the results more quickly.

Can I add this to my protein shakes?

Yes absolutely, you can enjoy The Power Booster with your shakes or any other liquid of your choice. It doesn't matter if you take it before or after your workout. As long as you take it daily, you'll notice the benefits.

What workouts does it help with?

The Power Booster is particularly beneficial for exercises that require explosive power, such as weight-lifting, HIIT workouts or sprinting.

Good product, could mix better

The flavourless powder is exactly how it sounds so is good for mixing into protein shakes you'd already be making.
The only issue I've had so far is that it doesn't mix so well so some residue of the powder is left in the shaker so I need swill with water to get all the grams I've put in.

Jeremy Stephens
Delicious, good quality protein shake.

I've been searching for the best shake that suits my needs for a while. I came across innermost and saw how you can mix most if not all other products they sell into one shake, kind of like creating the best concoction for your own gains. The chocolate strong is definitely the best tasting shake I've had in a long while. Definitely recommend with the power ( creatine ) mix.

Tom Owen
