Absolutely love this protein, difficult to choose a favourite flavour as they’re all beaut but my go to is cookies and cream. Mixes well, no lumps and most importantly no dodgy tummy like you can get with some protein shakes 🙌🏻 X4RI also make lovely overnight oats 👌

I love this recovery powder. I feel like it gives me everything I need to bounce back after long runs and intensive training.
I also took it with me to the Marathon Des Sables where it helped me turn around for multiple days of running across the Sahara desert.
The raspberry flavour tastes really yummy and was in fact one of the only things I could stomach in the heat.
Can highly recommend. Huge thanks Fission Nutrition 🙏

I have been using X4Ri Protein for many years now (probably 7+) as my post recovery drink. Having tried a few different brands, I can say that this is the best one I have tried hands-down.
It has a good mix of both protein and carbohydrates, whilst the added vitamins and BCAA’s make this a great all-round recovery drink. It mixes great and keeps me full for a while after a workout. I add in 5g of creatine into mine which also mixes in great with no effect on the taste.
My go to flavour is Banana, although I have also had Raspberry which is equally as good.

I’ve used the X4Ri Protein and the Strength Volume Protein and both have been fantastic additions to support my training. I marginally prefer the SVP as it’s better catered to my personal needs. I’d strongly recommend Fission Nutrition products to anyone out there as each one seems to be tailored for gaining or maintaining your performance level. Get involved, people.
