Here is one in Las Vegas. 
I thought I would provide the name of my Doctor who does prescribes rapamycin but his practice  is different from Dr. Green in New York. 

I have found him to be very knowledgeable and extremely helpful as he is versed and prescribes bio-identical  hormones, PRP, peptides and other healing modalities. See below.
