Appreciate myself for taking only 2 capsules for the first time, I still felt like I had too much espresso. Like slightly shaking hands and heartbeat for about 10 hours after taking it... Had also a little chest pain when walked and climbed stairs and it's not normal for me. It did give me a lot of energy and sweat during my morning training though. Going to give it another try and take one capsule instead .
