A Caution to Some...
For the first two-three weeks, it worked well; I had lots of energy, no pain, and slept well.  Then, it seemed to affect my nervous system (I have multiple sclerosis) and I felt a fluttering in my throat as if my heart or blood pressure were off kilter.  I checked the ingredients and checked on the amino acid specifics on a medical site.  By this time, it was passed the return time and I will now have to pay for an unsatisfactory item.  Also, no return slip or address included in the material that I could see.  It may work well for most, but a note of caution to some.  Amazon may want to do some checking on this item before offering it to others.
