I love that it does not cause a jittery effect while still giving me an extra boost of energy at the same time. HOWEVER, be aware that the product is placed into a much bigger tub making it look as if that how much you’re getting... it is only half full if even that. Serious case of false advertisement.

What is the difference between amino energy supplement like this versus a BCAA? Can you take both?
A shopper on Aug 28, 2018
BEST ANSWER: No need to take both. BCAA are just half (roughly) the aminos you need. This has both essential and branch chain aminos. This covers it which is why they just put general amino on the title and not bcaa which is just a portion of aminos.

How will prodcut affect my kidney and high blood pressure ?
