I just started taking Designer Whey protein and I'm not sure how much to take. The packaging recommneds 3-9 scoops per day. I looked online and I've seen people recommend as high as 1g/lbs of bodyweight to as low as .8g/kg of bodyweight. Anyone know how much is optimal? I do weight training for about an hour 3 days a week and HIIT for about 20 minutes 2 times a week. Thx
