I love my oats and whey in a shaker cup,never used a blender though,if it is thick i just add more water and some raisins.. yum yum

when i was a young lad trying to put weight on to join the army i used to ad a whole raw egg to my shake. noy that was hard graft. work out was childs play compaired to that. give it a go and oats will seem like an easy option. when your starting any new diet its hard to begin but time goes but and you begin to enjoy it. i never used to like tuna, in fact theres probaly a huge post by my old name Deano waffleing on about how i hated the stuff. know i look 4ward to it.

My post morning workout drink is 60gm protein and 80gm oats, in a blender, and its full ! I love it, its easy to consume and takes care of breakfast!
The amount of water doesn't make any difference, if its too thick add more, it just prolongs the pleasure of drinking it !

I tell you what you could try,soak your oats overnight in your shaker cup with water or milk,then when you go round to drink it just add your powder and the oats wont be as thick then,trust me.
