Work for longer periods,quicker muscle recovery, and quicker muscle repair when damaged, I also noticed better muscle tone when using White-E with vitamins B and C.That sounds an excellent thing for a lamping lurcher then sl.but what I meant was, how many rabbits, foxes and so on does it have the edge over a dog that's not taking it likeI think that's impossible to work out.but it apparently increases the speed of the fast twitch muscles and aids muscle recovery and other things.That's only going on what I've read up on it.
