Product Overview Signature Amino Boost

Amino Boost contains 8.5g branched-chain amino acids (BCAAs), which are building blocks of protein, in a 3:1:1 ratio of L-Leucine, Iso-Leucine, and L-Valine. We’ve also included caffeine, green tea extract, and electrolytes. It’s perfect during all stages of your gym session: Pre-, intra-, and post-workout. [1] Signature Amino Plus ENergy tub
  • 8.5g BCAAs
  • 100mg green tea extract
  • 100mg caffeine [1]

1Caffeine helps to increase alertness and to improve concentration. Do not exceed a daily intake of 300 mg of caffeine.

Caffeine contributes to an increase in endurance performance. The beneficial effect is obtained with caffeine consumption at doses of 3 mg/kg body weight at least one hour prior to exercise and only if any other caffeine consumption is avoided for at least 12 hours prior to consumption of the product in habitual caffeine consumers.

Pouch are no good once open can’t close them. Apart from packaging The Orange Mango is the best and Help During Workout Highly recommend. Blue Raz do not get that flavour the taste will effect you workiout.

I got the orange and mango flavour sample with an order I had gotten, the flavour wasn’t too bad, but by the end of it I had to hold my nose, and take it down. I decided to have this quite late at night a bit before I went to bed, the next morning I woke up feeling nauseous and the urge to go to the toilet. I spent 3 hours going back and forth to the toilet just feeling absolutely miserable. Finally after these long 3 hours, I managed to fall asleep. However, a few hours later I suddenly woke up with the urge to go to the toilet, feeling much worse and more nauseous, as soon as I approached the toilet, I started to vomit violently. My experience with this product is clearly not the best, in fact, one of the worst. I would not recommend this product, nor flavour.

Blue Raspberry is the best flavour - but for some reason it foams a lot. Takes a while to settle so you can add more water too.. Orange and Mango doesn't taste as nice, but it doesn't foam that much. I enjoy using this stuff. I drink it throughout my workout and it helps give me energy since I train in a morning with only a pre-workout whey in me. I'd rather the product came in a tub with a ***** lid. The seal isn't the best and is normally open again when I get the pouch from the cupboard.

Best flavor i have ever tried. It is very refreshing and tastes really good, makes you want to drink them. I'm not a fan of BCAAs, but I got several samples on the expo and used them in the next few days, and now ordering 2 packs of orange and mango, considering using them instead of coffee

Received a sample at one of the recent events and thought the orange and mango flavour tasted amazing...really refreshing! I would definitely recommend this product.

Better dose of ingredients compared to amino energy and cheaper, would recommend.
