Great little Amino

Posted by 5552397129101064109 on Sep 28, 2016

Great for a mental hangover, whenever I used to drink alcohol I would have a few days following where my brain just did not work right/feel right which could last for an entire week, now I just take a few of these before I have a drink and at the end of the night and they have pretty much eliminated the alcohol related brain fog... now I just need to find something for my general non alcohol brain fog :).

I took 2 tablet with Magnesium ( 320mg) also before exercise, After a few days, I begin to feel good against fatigue and started fat loss and muscle gain on the 3nd week after exercise. One advice is do not load yourself with too much carbohydrate food ( bread, swiss roll, rice)
