What we know about safety, and how little that is

The mouse studies reported no obvious toxicity, and that reassurance is far weaker than it sounds. Mouse tolerability is not human safety, only narrow doses were tested, and clearing senescent cells carries theoretical risks that a healthy young mouse cohort could never reveal.

This unit separates the genuine reassurance from the open questions, including a recent study where clearing senescent cells made a disease worse, and closes on the regulatory reality. Education only, never medical advice.
