I've had a few on occasions, some sort of choc variety, not bad. I prefer protein drinks more though. Always try to pick 'em up when they are reduced in holland and barrett, from 20 to 10 quid. They can help to take away the pian you feel after getting back into more intense exercises. I could do with one as i'm trying new exercise on back and neck and save to say i'm slightly sore to say the least
