Mine doesn't seem to specify, but it's 110 calories per scoop, so we can infer from your cousin's 900 cal version that mine is either lean or average. I mix mine with whole milk more for taste value and thirst quench, than for benefits, but it works out well in that regard. I try and have two drinks a day. I wake up, I make coffee. I eventually have something to eat, and then I take my multivitamin. Later on, I take my first large protein mix. Cue dinner, maybe another snack, more coffee, etc, and then I go to the gym around 11pm. I get home and have another big mix - usually the last thing I drink before bed, which is often 3-4 hours later.
