whats all this talk i here lately that the endocrine system of a young male is more likely to recover from exogenous testosterone administration than an older male?

saw it in a post here and another one on the am boards as well. also posted with a study to back it. but cant find them atm for some reason.

it makes sense, yet guys on here constantly parroting that the younger you are the worse you can **** up your HPTA.


any info on this?

thanks
