mass builder or whey after workout

I am currently on a bulk and would just like some help - I am using nutritech anabolic mass 45g protein 60g carbs post workout so my question is would a whey protein or the mass builder be best post workout and adding would adding bcaa into the intra/post workout make any change or difference

Not the biggest fan of mass gainers, but use it for now. Next time just use some whey and dextrose/vitargo. Take BCAA intra 20g. I just use them(+-20g) if I do a lot of cardio or trying to lose weight.

I think nutri tech anabolic mass contains vitargo.

Also not a fan of mass gainers.
If you aren't gaining mass and muscle, then you are not EATING enough.
Most mass gainers are too full of crap i have found. Too many sugars and flavourants. Just goes and sits right on your stomach. So for mass gainers are not really an option.

Eat clean, eat lots, get all you amino acids in, all of your omega oils in, pure whey and pre workout! What I live on!
