I have had nice increased energy stacking my ALCAR 1.3 gms, Green Tea also 1.3 gms,1.3 gms and 100mgs of RALA. I take this stack 3 X per day. I believe it is helping me lower my bodyfat and it probably is doing me a ton of good for other health reasons. I cap the ALCAR and Green Tea at about 650 mgs/cap. I also throw in a Celery Seed, Garlic and Hawthorne Berry with each dose to keep my BP down. I do this stack whether I'm using SD, M4OHN or as now, a test boosting stack of Rebound XT and Blue Rhino.
