Muscle is okay protein -- not the best, not the worst. MonsterMilk is pretty good for bulking. I get the feeling they were trying to copy BIG BLAST with that one, but, no super plamsa serum, so it's not quite in the same league.
I'll confess, I use the MM banana now and then because they really got that flavor down. Other than that, the Tropical orange, double chocolate, Fruit punch, banana and upcoming "Cinnamon Coffee Cake Flavor, BIG BLAST keeps me more than happy in the taste department.
I used to like the Weider Mega Mass chocolate but it was like 20 grams of protein and 135 grams of carbs from sugar!. LOL!
I'm a big believer that something can't just be good stats, it has to taste good. But there's no sense getting good tasting crap. The name of the game is protein, and not just cheap junk. You might as well make it something special. with BIG BLAST I get the best of both. If you're going to use a standard whey protein, I recommend adding some GEAR to kick it up a few notches.
