Aaron Marino of alpha m. addresses two questions.
Question 1: Should you keep your men’s suit jacket when the suit pants don’t fit?
Take the pants to the tailor and see if they can let the pants out. Typically, pants can be let out by 2 inches. You may get more wear out of the suit. If you can’t do that, then definitely save the jacket and wear it as a sport coat.
Question 2: What are some supplements for a 16 year old who is trying to get buff?
Creatine, CLA, and other supplements are not advised. Your body is like a testosterone producing factory with the perfect conditions for progress with proper nutrition and workouts alone. Take a good quality multivitamin from whole foods concentrates.
