Test Results Back: 470ng/dl 21yr Old Male

I just got my test back and the results came in at 470ng/dl. I am 21 years old 6,1 and 205lbs. Im concerned that while this is in the “normal range” its still pretty low given my age, I lift heavy and eat pretty well. With these numbers should I follow up with my doctor?

Some extra info: The day I got the blood work done I had a big meal before hand and was feeling a little sluggish, not sure if this makes a difference.
