How long does FOXO4-DRI take to work?
In the first week of FOXO4-DRI, mouse-model markers (improved fur density, kidney function, fitness) emerged within 10 days. Around week 4, off-pulse. Effects in mice persisted for weeks. By week 8, no human long term data exists. Response varies between people, this is the commonly reported pattern, not a guarantee.
Week by week
- Week 1: Mouse-model markers (improved fur density, kidney function, fitness) emerged within 10 days.
- Week 4: Off-pulse. Effects in mice persisted for weeks.
- Week 8: No human long term data exists.
