I would take it all after, but then again, it matters how lean u are.
The perfect post workout shake is about 60grams of waxy maize and 40g of protein ( isolate)
you cant just generalize like that..... for some this might be a horrible shake.
some people need much less carbs than that... some people much more...for two reasons, one is the differences in metabolic rate between dif. bodybuilders...and the second reason being styles of training. a guy like jay cutler who does massive amounts of volume and depletes huge amounts of glycogen... 60 g's would be too little, but for a h.i.t. trainer like mentzer 60 would be far above whats needed to replenish what was used during training.
some people need more protein than that, some people need a different kind of protein than that. the higher lean body weight you get the more protein is needed..the larger tha muscle hit, the more protein that is needed. and some people are lactose intolerant..while some people would benefit from a non-isolate that contains the small amount of added fats and sugars..some people would need a whey/casein mix...
