No doubt! In a previous thread I posted early in my first run of Alphamine (3rd day maybe? I was still at 1 scoop in the morning) that I was so juiced that I needed to do dips at my desk at work or else I felt I was going to explode! I can't ever remember having that much energy. As with anything, my body soon adapted but I still look back at that and laugh....plus, the increased body temp helped out during those days it was still bitter cold here! I'm almost done my alphine run of eight weeks. While it's worked well, I don't think I've gotten the results I have from the good ol' reliable ECA stack. That's purely based on recollection - didn't do any logs. On the plus side for Alphamine, though, when I'm at ECA 3x a day, I feel pretty "Zombified". I never felt that way using Alphamine - always alert and focused (more-or-less). Plus, I really like the Raspberry Lemonade flavor and aroma.
