I've seen Malto in Health Options before, with Dextrose, go to those Chinese drugstores (like the ones in SM Hypermarket (near tiendesitas), greenhills, or those kiosk/booths and look for Dextrose (blue can, not Glucose)
Thanks for the reply Theveed. Have you had experience buying and using these products? Are they better than just using Gatorade together with whey as PWO drink ?
