It is usually not recommended to get top surgery at 13. One should atleast be 18 years of age to get top surgery. 

Usually, top surgery is suggested when you are 18 or above the age of 18. But you can get top surgery at 16 if you have your parents approval and after consulting with a qualified doctor. 

If you don't take testosterone or undergo top surgery, you can still build your pecs by lifting weights. Pecs, short for pectoral muscles, can grow with exercises like chest presses and push-ups, which target these muscles. Pace yourself, use the correct form, and be consistent with your workouts. Your pecs can still develop even without testosterone.
