Life changer for competitive sports

Since taking Cordyceps I have seen a huge improvement in my endurance and time when it came to Hyrox training and competing. Furthermore, my recovery has been much quicker.

In the morning I mix this in my coffee with Lions Mane and I’ve found that I am more focused and energised throughout the day.

I’ve recommended both of these products to my friends.

That's amazing, Sarah!

Love that you've seen such a huge improvement in your endurance and time with your Hyrox training and competing - that's exactly what we hope to see with Cordyceps! So great to hear your recovery has been much quicker too.

Your morning routine of mixing it in your coffee with Lion's Mane sounds perfect - fantastic that you're feeling more focused and energised throughout the day!

Really appreciate you recommending both products to your friends - that means the world to us!

These are amazing. They give me the energy that I need to get through my days. I can definitely feel a difference when I don’t take them.
