This is a reply about dr Morris in Southlake Texas.  He has a website called The Private Practice.

His main business is hormone replacement.

He prescribes Rapamycin on request unless it is against his medical judgement. 

He charges me around 300 $ for a 30 minute FaceTime visit twice a year.

his prices may have gone up.  My insurance pays for most of my prescription.

he is not a quack or a dr feel good.

This is an experimental regimen.  It is not magic. I think the benefits are real.  I know that they are modest. At my age 70,

in 6 weeks, I will take what I can get.
