Primary concern: Model organism only—no mammalian or human data. No baseline pharmacokinetics or bioavailability data reported. Zero citations to date …
Preliminary
Two-phase aging model reveals critical vulnerability period in flies and mice

This preprint offers an intriguing mathematical framework showing aging may involve a dangerous transition point—but it's early-stage work awaiting peer review and replication. If confirmed, it could refocus aging research …
