Your results look perfectly fine my brother.. Your DHEA levels are a bit up, but nothing to worry about.
You can try different things to get better erections, like 5mg ciales daily. And your free T3 can be also go up a bit, by just taking iodine and selenium. Usually just a good multi vitamin does the work.
Anyway, there are some supplements plants based, that might help to. Like long jack, tribulus and so on. For me, while ago, just some test boost helped me when I had any ED issue. Although it didn´t change my T levels, it gave more libido and better erections.
I would do everything, but not jumping in TRT, with those labs results. Just see how many guys dont do well on it, with that of numbers you have, there is no way need it.
However, some guys have a really heavy life style, by working a lot, taking care of family and so. For those, that even dont like the kind up´s and down´s of being natty, and have all these things to take care about, I´ve seen they all would prefer the stability of TRT over any kind of natural levels. If you feel you might need some help, just see a specialist and have a talk. Number´s are not everything, and some times is better to go with TRT, then take some other pill´s to "help" go through a hard time in life.
