How much time would it take a 18 year old who is 5, 8 & 165 pound to build muscle mass?

Activity helps: anyone can start building muscle mass with a throughtful, appropriate workout plan. Building cardiovascular fitness is even more important (and useful for long term health). Muscle mass will start showing up if a teen has appropriate levels of testosterone (hair on face & body, perhaps history of acne, deepening voice). Muscle mass can start showing up in weeks
