I did see that he is now taking testosterone ( pills were in his car) I have not been spying.
Testosterone is not usually given as pills (sometimes sublingual lozenges from a compounding pharmacy). The usual methods of delivery are gels, creams, patches or injections. This makes me question whether what he has is legitimately prescribed, or whether perhaps he has been buying something off the internet or if it's just some kind of supplement touted as a testosterone booster. Did you get any more information off of the label?
Your H is relatively young, correct? (under 45?). Testosterone deficiency in this age group is uncommon (not impossible). Undiagnosed hypothyroidism is one possible cause of low testosterone in men.
