If you only took it five days, you probably didn't do much damage. I took it for about 6 weeks... which was a *huge* mistake! It overstimulated me, causing *severe* anxiety and heart palpitations for the following 3 months, after which I was tanked. Instead of boosting my adrenals, it demolished them. Prior to my HC debacle I was semi-functional. I haven't been the same since I took it five years ago. It is one of the worst substances I have ever willingly ingested.
