Try (I have never been to this doctor and I copied this info from a post he made here.):
Howard Chipman MD
"My name is Howard Chipman MD and I have been treating patients with young plasma for anti-aging, dementia and other age related disorders for over a year with good results. " "My clinic is the Atlantis Clinic in Oldsmar (Tampa) Florida. "
A year ago, I was told by someone who has gone to him that he prescribes rapamycin.
There is also Richard Gains MD at https://lifegaines.com/ . I got a script from him , filled at Tailormade. I've since gotten some from India, Biocon, but I've been reading that maybe this isn't a good source. I have not been taking this consistently lately. Was doing it, per Dr. Gains, at 3 mg per every 10 days. I did try going up, starting with shortening the time to weekly, but seem to get Herpes breakouts when I do that.
