I need to get strong and look like i have some m in my body i dont care how long it takes.?

Im a Young male turning 19 this May im 5 foot 7 and weight 116 i ate lots of junk food and never gain weight because of my metabolism. I cant really lift that much weight at the most 80lbs and my arms are really skinny. I wanna start getting some m in my arms i dont care what it takes i will follow any regimen. i got a pair simple 10 lbs dumbbells and a pull up bar. i have some protein i recently bought idk what else to say but im sure this stuff will help
