I haven’t read all the comments, but I think you considered using a lot of audios to produce more testosterone but didn’t consider improving or supplement your nutrition or did you?
Take a break from the fields and improve your nutrition, get a multivitamin supplement, especially you need vitamin D, vitamin C, zinc and magnesium.
Get tongkat ali (Longjack) or Maca root suplements, They are adaptogens and It will help you with hormone production, energy and mood, do your research. Consume in moderation, Start Small
also ensures that you have a good sleep schedule, if you don’t have it currently after trying what I have suggested you should sleep better.
Without good nutrition, hormone-inducing fields do nothing, it’s like trying to start an engine without gas.
