## Questions & Answers

**Q: The label looks different compared to the previous one I got, is it still the same OPTIMUM NUTRITION product?**
A: As you evolve, so do we. The part of our mission is to help active individuals better understand OPTIMUM NUTRITION products. Now choosing the right product for you is easier with more visible product benefits, features and flavours on each tub.

**Q: Why my tube is not full to the brim?**
A: Due to vacuum packing some of the tubs may appear to be two thirds full when opened. This is normal as the powder settles and does not impact on or decrease the weight or number of serves listed on the label.

**Q: What is the best way to prepare my sport nutrition drink?**
A: For optimal use, follow serving instructions on pack.

### ⭐⭐⭐⭐⭐ This is not fake !
*by R***A on 28 November 2019*

This isnt fake at all . All of the people complaining that there isnt any safety seal ( The white circular foil seal once opening the lid ).........there is ! It's just came off with the lid . Look under the lid and the seal is there and must of came off when unscrewing as mine did . Very common and happens with lots of supplements but it is sealed and have got batch numbers so dont worry about it being fake it's not . Great powder
