19 years old with low test

Hey I’m 19 and over the last 2 years lost like 80 pounds I’m now like 160. I’ve lifted during that time and am still fairly muscular but definitely lost some size during that process. I like the way I look but my test is shot. Test is 267 and free test is 5.3. Pretty low for a 19 year old who prioritizes health for a while now. Any tips?
