Fantastic stuff

Love this stuff has helped me put on the weight that was needed. Use it as part of breakfast and as a post workout

Not just for gaining weight

I use this for breakfast and pre training for fuel and with the high amount of carbs it’s an easy option pre training or pre race. Strawberry and chocolate flavours are great

A hurried purchase

Bought this in a hurry one day and regretted it since. Mixed poorly and doesn't taste great, one to avoid for me.
