29 is too early to consider a lifetime of trt.
Do try optimizing everything first, and see how you feel. Get your diet on point, take vita d3 I agree your test is low at your age, but I wouldn't consider trt until 40. Its low but not low enough where you couldn't turn things around by respecting your body, and giving it what it needs to flourish first.
Do you smoke, drink, nightclub, stay up late,drugs etc..?
