First dose was this morning, and began to get that "on" feeling about an hour later, like a rush of warmth over my body that stayed all day. I was a little hotter at work today so im inclined to believe that this may be good for fat loss. Hit the gym this afternoon and had a good pump thoughout. My arms swelled up nicely. Not much to be expected for a first day but we'll see how things go in the days to come.
