Rehana Liyakat using these buster Plenish energy drink since good time.I had seen those tins I had ordered and receive within 48bhours at my home. This is work. Calories wise few products are really great and it's work. But as I can remember during check up my doctor told me one product is good and suitable for some one but not necessary second will get similar results. So get few one from Plenish,see how it work in your body system.
