Senolytics & senomorphics — clearing zombie cells for longevity.
Senescent cells accumulate with age, releasing inflammatory signals that damage surrounding tissue. Senolytics clear them. Senomorphics neutralize them. Here is everything you need to know.
- Senescent "zombie" cells accumulate with age and release inflammatory signals that damage nearby tissue.
- Senolytics clear senescent cells; senomorphics neutralize their harmful secretions instead.
- Fisetin and quercetin are the most studied nutraceutical senolytics; dasatinib is a pharmaceutical example.
- Intermittent "hit and run" dosing is the dominant senolytic strategy in current research.
What are senescent cells?
Senescent cells — often called "zombie cells" — are cells that have stopped dividing but refuse to die. They accumulate with age, after DNA damage, or after cellular stress. Rather than undergoing apoptosis (programmed cell death) they enter a permanent arrested state and begin secreting a toxic cocktail of inflammatory cytokines, proteases, and growth factors known as SASP (Senescence-Associated Secretory Phenotype).
SASP damages neighboring cells, promotes chronic inflammation, impairs tissue regeneration, and drives many hallmarks of aging: fibrosis, immune decline, metabolic dysfunction, and increased cancer risk. By the time you're 60-70, senescent cells may constitute a significant fraction of certain tissues.
Senolytics vs senomorphics
Kill senescent cells selectively. Target anti-apoptotic pathways that allow zombie cells to survive. Used in intermittent protocols (not daily) — typically one 2-day cycle per month.
Do not kill senescent cells, but suppress SASP — reducing the inflammatory signals they release. Can be used daily. Lower risk profile than true senolytics.
Key senolytic compounds
Connection to peptides
Several peptides on PeptideCompare work synergistically with senolytic protocols. BPC-157 supports tissue regeneration after senolytic clearance. MOTS-C improves the metabolic environment that drives senescence accumulation. Epitalon has shown telomere-stabilizing effects in research. GHK-Cu promotes tissue repair and has anti-inflammatory properties that complement senolytic protocols.
