I still have 10 bottles left of the old MD6 formula (with the nor-ephedrine). I have some Ephedrine HCL caps (12.5 mg per cap), and was wondering if anyone has stacked Ephedrine HCL with the old formula of MD6? If so, how much Ephedrine HCL does everyone recommend to stack with the old MD6? I am not particular sensitive to these type of supplements. Thank you
