Be very careful
When I received the Quantumind it made me feel awake for an hour and tried it for 3 or 4 days and every day it made me very irritated and I crashed after 90 minutes every time……There’s way to much caffeine….Quantumind said there’s no crash but that’s not true…. Don’t take it if you are going on the road because you might fall asleep….. That’s my experience but maybe different for other people…..It takes forever for them to give you your money back….
