Can you post the reference ranges that were used for your labs?
What other blood work can you post?
E1, E2, E3? Prolactin? SHBG? LH? FSH?
There are lots of good ideas in this thread about healthy habits for trying to "optimize" testosterone levels. It helps if you can paint a more clear picture as to why you are subclinically low for T levels. Being able to post more blood work will help. For instance, it may be able to be determined if you are secondary or primary hypogonadal. Whether you are over-aromatizing, or maybe have excess T bound to SHBG or protein albumin.
Optimizing T levels via ideas mentioned in this thread certainly won't hurt, but you may not notice any changes anecdotally or via blood work which can be frustrateing. That is when further investigation like I mentioned above is warranted.
