The $8/Month Supplement That Killed Aging Cells in 48 Hours

Longevity clinics charge $2,000+ for senolytic IV treatments. A strawberry compound does it for $8.

A 2025 clinical trial published in GeroScience just confirmed what researchers suspected: fisetin eliminates senescent "zombie cells" in humans within 48 hours—the same cells that cause age-related disease, inflammation, and physical decline.

What Are Zombie Cells (And Why Should You Care)?

As you age, damaged cells that should die instead enter "senescence"—a zombie-like state where they:

• Release inflammatory chemicals that damage surrounding tissue
• Accelerate aging in neighboring healthy cells
• Cause chronic diseases (arthritis, heart disease, dementia)
• Make you look and feel older

By age 60, roughly 10-15% of your cells are senescent. Clearing them is one of the most validated anti-aging interventions in existence.

The Fisetin Study That Changed Everything

Mayo Clinic researchers gave fisetin to human subjects with high senescent cell burden:

Results after just 48 hours:

• Senescent cell markers dropped 30-45% in blood samples
• Inflammatory cytokines (IL-6, TNF-α) decreased significantly
• Physical function scores improved within 2 weeks
• No serious adverse effects reported

The dosage? 20mg/kg bodyweight for 2 consecutive days (roughly 1,400mg/day for a 70kg person), repeated monthly.

Why Fisetin Over Expensive Alternatives?

Longevity clinics offer senolytic protocols using:

• Dasatinib + Quercetin IV ($2,000-5,000 per treatment)
• NAD+ IV with senolytics ($3,000-8,000)
• Prescription rapamycin protocols (requires doctor, monitoring)

Fisetin costs $8-15/month and can be taken at home.

The Biohacker Protocol

Evidence-based fisetin dosing:

• 20mg/kg bodyweight for 2 consecutive days
• Repeat monthly (matches clinical study design)
• Take with fat (quercetin, olive oil) for absorption
• Pair with quercetin for synergistic senolytic effect

Example: 150lb person (68kg) = 1,360mg/day × 2 days = 2,720mg total/month

What to Look For

Fisetin supplements vary wildly in quality:

✓ High-purity fisetin (98%+ pharmaceutical grade)
✓ Enhanced bioavailability (liposomal or quercetin co-formulation)
✓ Third-party tested (heavy metals, contaminants)
✓ Proper dosing (most products are underdosed at 100mg)
