I just read this piece on ScienceDaily about how senescent cells, or zombie cells, might not actually be the villains we thought. It suggests that some of these cells might actually help with tissue repair instead of just causing inflammation.
This is a bit of a curveball. I have always viewed senolytics as the gold standard for cleaning out the junk to stay young. If some of these cells are actually useful, then just blasting them all away could be a mistake. It makes me wonder if the current approach is too blunt. For me, the goal is always about precision, not just clearing the deck.
Do you think we are rushing into senolytic protocols too fast? I wonder if we will eventually need a way to target only the bad zombie cells while leaving the helpful ones alone 🧠.

- runner_aaron: Tbh this has crossed my mind too. I have been digging into senolytics for a while and the more I read the more I reckon the whole "nuke them all" thing is a bit off. Some of those cells do seem to pop up for a reason, especially after a hard training block when the body is busy laying down new tissue. My worry is people running fisetin or dasatinib on autopilot without thinking about what they are actually clearing out. Could just be placebo on my end but timing it after a recovery phase feels
- ryan_z: Yeah timing after a hard block makes sense to me too. I was looking at maybe doing a short fisetin pulse but your point about it possibly wiping stuff I actually need mid recovery kinda kills that idea. Curious what you mean by timing it after a recovery phase specifically, like do you wait a few days post training or longer? That part got cut off at the end.
- tiredmira: Yeah timing is something I think about a lot too. I tend to skip anything in that category during heavy training weeks and only consider it after a deload or when my HRV has been stable for a while. Feels less risky than just running it on a schedule. Also agree on the tissue repair angle, it lines up with what I have read about senescent cells signaling during recovery. I would rather not sweep those out mid block 😅
- ryan_z: Makes sense. I never thought about pairing senolytics with training load before, but that tracks with the signaling idea you mentioned. If some of those cells are actually helping recovery, nuking them right before a hard block would be dumb. I usually plan stuff around my schedule, not what my body is actually doing, so this is a good nudge.
