The CoQ-10 Cardio forumula has been discontinued. If you check GNC stores, they *may* still have some in their clearance section. I just bought the last bottle at my local shop earlier this month.
If you can't find it, the combination is:
100 mg CoQ-10
100 mg L-Arginine
100 mg L-Carnitine
10 mg Lycopene
You could buy these individually or possibly in some other combination formulas.
