Sources

Nutrition from the brand's Chocolate Fudge Supplement Facts image: 1 scoop (33 g), about 28 servings (2 lb), 130 kcal, 2 mg cholesterol, 50 mg sodium, 1 g carbs, <1 g sugar (recorded as 1), 30 g protein; fat is not listed on the panel, so fat_g is null. The same values appear on NIH DSLD 4043 (Chocolate Fudge 2 lb, entered 2011-12-23, marked off-market as that UPC record), which also gives the typical amino profile per serving (leucine 3210 mg, isoleucine 1860 mg, valine 1680 mg; used for leucine_g and bcaa_g), 'Contains Milk, Soy and Wheat', and 'Naturally and Artificially flavored'. Neither source lists the full ingredients, so sweeteners is null. Formula also contains the brand's glutamine complex, SI complex (alpha-lipoic acid, d-pinitol, 4-hydroxyisoleucine) and D complex (protease, lactase) per brand page; the glutamine complex includes N-acetyl L-glutamine and Glutapure (L-glutamine), so added_amino_acids is true.
