Do you take them,  dextrose, waxy maize starch, Vitargo etc? - Dextrose
How much do you take?   30 grams of dextrose and 30 grams of WPI in 250-300ml full cream milk
Where did you buy it?   Big W home brew section
How much did you pay?   $2 or so for may be 1 kg or similar can't remember exact details, it was Brigalow brand. 
What are/were the results?   Put on 6-8kg of solid muscle in a month while shedding every last ounce of visible body fat......only kidding, made no difference that I could tell, but made the shakes taste nice and sweet.
