This is more realistic.
You can't get 20 lbs of muscle in 4 months and only 5 lbs of fat unless you're juicing. Maybe 50/50 if you're super serious.
If you're planning to put on muscle mass you need to also eat at a calorific surplus to maximize muscle gains. If you're a body builder (which he's not) you would put on the mass and shed the fat after.
Anyway he looks more like a horse (solid), you can definitely tell he put on some solid mass. Like it!
