Your free T is above 10 so I am surprised you are having low T symptoms. Seems like symptoms seem to start showing up when free T is below 10.
I am 52 and have about similar labs (see below in footer). Except my free T is below 10 measured and just barely above 10 calculated. So I am literally on the fence of T levels.
So far I have found nothing that has made a pinch of $hit of difference to increase T level naturally. However weight lifting is said to have some effect. I happen to dislike weight lifting so I have not gone to that....yet.
Also losing weight can help lower Estradiol and this can help some folks feel better. DIM supplement can help some folks but has been pretty inconclusive for me. Boron was a complete failure. Did nothing or even made T levels a bit worse.
If you find something that works please report it. Lots of folks would love to know and try something that might work.
Understand however that any “natural” method will probably only result in increases in the double digits. While most men at some point may need improvements in the triple digit increase.
So like you say. With your levels you may be abme to feel better with small natural increase. At least for a while. How long is anyone’s guess.
FlyingFool and Neal, would you consider trying Clomid, or HCG with an AI?
Since your balls seem to be working you could also look into Novadex for 2 months.
As far as I know all of these are prescription so maybe you don't consider them natural, like an OTC supplement?
Honestly fellas I've been at this TRT for 3 years and I am dialed in BUT TRT is nothing like natural T production. It feels way different and not in a good way. Do everything you can to get your own production going if possible.
