Energy for Study

By Martin reviewed on 4/09/2021

I use this for pre-excercise and during basketball games.
My son relies on it to give him the boost he needs to maintain focus and provide the energy while studying for his engineering degree - he was very concerned when we ran out! Thank you for the prompt delivery!

I gave Amino Z a look after my regular supplier had run out of stock, and not only was the item a cheaper price, but the delivery was super quick and packaging was perfect for the item. I enjoyed the process a lot, hassle free and fast, and will continue to use Amino Z for future purchases

Good pick me up

By Jacob reviewed on 10/12/2020

Verified buyerA verified buyer is someone who has purchased this product from Amino Z

Nice to have instead of a coffee for a bit of a pick me up. It is a mild effect - but better than coffee and of course has a decent amount of amino acids included.

Best amino acids

By Olivia reviewed on 19/06/2020

Verified buyerA verified buyer is someone who has purchased this product from Amino Z

Optimum Nutrition makes the best Amino Acids. There's a little caffeine, so it's replaced my daily coffee; it's cheaper, more refreshing and easier on-the-go. There's such a good range of flavours, my favourite is blue raspberry.
