Tasty

Mixed in with Greek yoghurt makes a perfect snack before bed

Good casein

Mixes well and tastes good (important stuff - it can’t work if you refuse to drink it)

The added glutamine is a nice gut health benefit. I don’t wake up quite so ravenously hungry during a cut with a scoop of this before bed.
