I haven’t felt this good in years. Usually I’ll be working on cars after working (my job requires me to walk/run around for at least five miles over the course of several hours). After all that I’ll fell like garbage; sore, tired, run-down and beat up. When I started taking this supplement, I felt different, in a good way. No rashes or side effects other than when I took my car down the road I felt like everyone was driving like a slug and they needed to get out of my way! When I wrapped up work and fixing my car I was only a little sore; usually I’ll wake up nearly cramped and in some pain and discomfort. There’s a lot of stuff in this supplement, and it does taste like a pet store coming down your throat two times either at once or throughout the day, but I still feel better. I haven’t felt this good since early high school!
