i have no idea about hrt because i never had to research that but someone correct me here if i am wrong. his dr perscribed him 400mgs of test every week which obviously means that his levles were super freaking low so wouldnt doing the perscribed dose just bring your levles back to normal? if so then you would need 800mgs a week just to get that extra 400mgs. maybe im seeing this wrong but it definatly makes sense to me
