@Tanya Oliver so far I really haven't noticed any results with NAD yet, I've been taking the dosage you had recommended to start with, 40 units 3x week. Should I increase that? As far as the 5-amino-1mq, I was very excited about that one, but I took the lowest starting dose(20 units) and immediately felt super light headed, to the point of worrying I would pass out .. so I haven't taken that one again yet. Have you ever had that experience with 5 Amino?
