What a strange question,

If it helps I mix mine in protein and water in a shaker, and the amount of water depends how thick I want or if I'm paying attention when filling my shaker, sometimes I get sidetracked and fill the large shaker, and it tastes very watery.....lol does that help in anyway, might I add if I'm having it before bed I will use less water so I don't have to get up in the middle of night...hope this helps

The amount of oats I use is completely dependant on time of day and macros for that given day/meal, typically either 50g-100g
