Beware of the proprietary formula!
I didn't read further about the propietary formula, especially ginseng and the rhodiola. I found other helpful review on Amazon that these herbs potentially lower blood pressure and might interact with certain medications. Also it might be bad for those who have autoimmune conditions. I tried this for 2 days but I had to stop after reading this. So far I didn't feel anything yet, but I didn't use the patch for full 8 hours. Too bad cause I really like the idea of patch supplements and the B complex in this patch are good quality, but they need to keep it clean and basic without unnecessary ingredients that can be harmful for some people. Other than that, patches are good size, it sticks well.
