About Reflex One Stop Xtreme

All-in-one protein shakes are designed to pack all the ingredients needed to help improve training performance and recovery. Instead of buying separate products such as BCAAs and creatine, these supplements already contain suitable doses.

The list of ingredients for Reflex Nutrition’s One-Stop Extreme is – well – extreme! Maybe “exhaustive” is a better word, as you would probably need a recovery shake to revitalise after reading them and researching them all.

At the end of the day, if you’re looking for a protein powder that contains just about everything you’ve read about in fitness magazines – this is it.
