Beat me to it. Your body type doesn't affect what set/rep ranges benefit you the best, it only determines how a diet will affect you, and that's only vaguely. For instance, I used to think I was endo, which for many means little food = tons of fat gain, but as it turns out I can eat a decent load of food so long as it's not starch and not get fat. I'm probably just a meso with poor insulin sensitivity, lol, though I don't hold on to muscle easily (I gain it fast, lose it fast).
As Zir also said, muscle fiber type will largely determine what set/rep ranges work best for you. So that's something you'll have to play around with to figure out what's best for you.
I responded very well to 3-4 sets of 6 reps per exercise, with 3-4 exercises per body part max a day. Even though I followed a bodypart split I still designed my workouts by movements, so I worked all 3 big movements at least twice a week (one day per body part, 2 leg days, assistance exercises often hit some parts even more frequently). I do respond to 20 rep squats very well, though.
