N-large is inadequate as a gainer, for a couple of reasons. 1: a low carbrotein ratio. 2: under 1000 calories per serving. 3: it tastes like shit. N-large is a very effective post workout supplement with a great carb/protein ratio for that purpose, and also a nice combo of complex, and simple carbs.
Looks like Serious Mass has 50g protein, 260 (or so) carbs per serving, 1,250 calories, and it is enriched with vitamins, and a great amino acid profile, 5 creatine per serving, and 5 glutamine for 30 bucks.
