the infamous protein shake...
quick question...may be stupid...can u make large amounts of protein shakes..i mean..it would be easier to make a gallon of the stuff than 20 oz each time...does anyone know if u make a big batch in a gallon bottle or more that it will stay good...i want to suck down these things on my lunch break at work but already have them made in advance...combined with skim milk is it all good if it stays in a big jug for a while or what?...this way if i make large amounts I can get a HUGE amount of protein per day...stupid question i know...anyone know if its cool for protein shakes to sit around for a while???????
