The first day I took it I had more energy, but then felt worse after taking it the next two days, however, I had a few other interfering factors. I stopped taking it for now and will go for a "round-two" once I can try to isolate it as the only change again. If I do end up getting good results I will let everyone know. One thing I did notice is that that my low-grade fevers, which I was having about 50% of the time, are down to about 20% of the time. I'm not certain this is due to the gcMAF, but it may be as it happened the day I started it and has held.
