Hello, I would like to ask seriously to some doctor or experienced member here. What are possible reasons of "can't grow facial hair, have gynecomastia, lack confidence, have trouble verbalizing my thoughts, brain fog, low mental and physical energy, trouble concentrating, slight depression, anxiety" and so on? Is it always testosterone deficiety? What reason can cause this? My ideas: 1. Low testosterone levels. 2. Imbalances in testosterone/estradiol levels. 3. High testosterone but low free testosterone becouse of SHBG What are the others cousing this? Becouse once I did bloodwork done and my levels was ( I am 21 years old ) Estradiol 66 pmol/l <28-156> testosterone 13,44 nmol/l <8,64 - 29 > DHEAS 8,14 umol/l < 5,73-13.40 > Cortizol 482,5 nmol/l <171-536> My testosterone is not that low. Thank you very much and sorry for my broken english.
