Part 18
The Longevity Drugs

Picture a healthy man of 48 who gets rapamycin from an online clinic after a ten-minute video call. He takes it every Sunday. He has no idea what his cholesterol or blood sugar has done since. He tells me he is “playing the long game.” He may turn out to be right. He is also a volunteer in an experiment with no control group, no monitoring, and no one writing down the results.
Clinical scenes in this edition are explicitly labeled illustrations. They describe imagined situations used to explain medical decisions, not documented patients, diagnoses, conversations, or treatment outcomes. They should not be read as evidence that a particular intervention works. Personal recollections are recollections, not medical records.
Evidence grade (draft mapping). 10 questions; a question with mixed evidence counts under each grade.
- 258. What is rapamycin, and why are people so excited?It is a transplant drug that, at low doses, is the most reliable life-extending compound ever tested in animals.DPreclinical / mechanistic
- 259. What do the human studies show?Not much yet. Low weekly doses appear reasonably safe over a year, with only hints of benefit.BLimited or small human studies
- 260. What are the risks of rapamycin?Mouth sores, higher cholesterol and triglycerides, higher blood sugar, slower wound healing, and, at higher doses, a weakened immune system.EEstablished clinical knowledge
- 261. Should I take rapamycin?I do not recommend it for healthy people outside a clinical trial. If you choose to anyway, do it with a physician who monitors you.JClinical judgment / author synthesis
- 262. What are senescent “zombie” cells?Damaged cells that stop dividing but refuse to die. They release inflammatory chemicals that harm nearby healthy cells.EEstablished clinical knowledge
- 263. Do senolytic drugs work in people?Not yet proven. Early human trials are small, and results have been mixed.BLimited or small human studies
- 264. What are senomorphics?Drugs that quiet zombie cells instead of killing them. Rapamycin and metformin may partly work this way.DPreclinical / mechanistic
- 265. Are there other drugs being studied for aging?Yes, mostly old drugs being looked at in a new way.JClinical judgment / author synthesis
- 266. Why is it so hard to prove a longevity drug works?Because the outcome that matters, living longer, takes decades to measure, and “aging” is not an official disease that regulators recognize.JClinical judgment / author synthesis
- 267. If you had to rank today’s “accidental” longevity drugs, what would the order be?SGLT2 inhibitors first, GLP-1 medicines second, and everything else well behind. Both were developed for diabetes, and both turned out to protect far more than blood sugar.ARobust human trials
