It's what I use after every workout! I use half a serving (2 scoops). Perfect post workout shake and it is pretty cheap too (not to mention it tastes decent).
Yeah, Its exactly what ive been using. What ive been doing though is having 1 shake (4 scoops) pre-workout and 1 shake (4 scoops again) post workout giving me a severe boost of carbs and protien!
I also have a shake of prolabs "advanced whey" (2 Scoops) just before I goto my bed at night. So from shakes im getting in the region of 140g Protien!
