I am finishing a 3kg tub of ISO Whey Chocolate. Great for oats in the morning. It's a fine powder so it mixes easily with no lumps.
Price : 5 out of 10 ( I think it was R540 +/-)
Taste: 8 out of 10 when added to oats
5 out of 10 with water (same as any other lean protein powder)
7 out of 10 with milk or a milk/water mix (It has a unique choc flavour, hard to describe, doesn't taste as artificial as other supps to me)
I can't comment of effectiveness, as I do not use it to bulk, simply to replace the other crud in my diet. I would expect any Biogen powder with higher carbs to taste as good if not better than ^this^
