I bought this to help me with muscle recovery after a stay in ICU. It definitely helped me recover muscle strength and gain some weight.

Mix it with either oat and soy milk until thick consistency and leave it to chill in the fridge. Taste almost like alternative chocolate mousse!

Have been using casein in my yoghurt and overnight oats to provide that thicker texture and has been great. Would honestly prefer the flavourless stuff though.

Tried the chocolate : tastes good, helps curb my snack cravings. Thick texture : I mix with water which helps thin it without compromising flavour.

Love this casein...took a little bit to get used to as it is such a different consistency to whey when I mix it with oats but great for staying a bit fuller. Def recommend!!
