Beginner Senolytic Stack: Start Here With Evidence-Backed Basics

Expert Summary

The simplest evidence-backed senolytic protocol: (1) Fisetin 20 mg/kg × 2 days per month for senolysis, (2) Quercetin phytosome 200 mg/day continuous for anti-inflammatory maintenance. This covers senescent cell clearance and ongoing SASP suppression with two natural, well-tolerated compounds requiring no prescription.

Key Facts

• Month 1: Fisetin 20 mg/kg × 2 consecutive days (take with fat-containing meal). Quercetin phytosome 200 mg/day starting from day 1.
• What to expect: Some users experience mild fatigue or GI discomfort on senolytic burst days — this may represent the normal cellular response to dying senescent cells releasing their SASP contents. Typically resolves within 24 hours.
• Month 2: Maintain daily quercetin phytosome. Take second fisetin burst (same 2-day protocol). Begin to notice: improved energy, reduced post-exercise soreness, potentially lower inflammatory lab values.
• Month 3: Third fisetin cycle. Begin tracking: hsCRP, IL-6 (compare to pre-start baseline). Most users see measurable reductions by month 3.
• Scaling up: After 3 months, consider adding spermidine (2 mg/day continuous) as a third agent. After 6 months, optionally consult a longevity physician about D+Q evaluation.
• What not to do: Don't start multiple new supplements simultaneously. Don't exceed the 20 mg/kg fisetin dose seeking faster results. Don't skip the fat co-administration (absorption drops significantly without it).

Frequently Asked Questions

How long until I feel something from senolytics?

Some users notice improved energy and recovery within 1–3 cycles. Measurable biomarker changes typically require 3–6 months. Structural cellular improvements (reduced senescent cell burden) occur without necessarily being felt directly.

Should I tell my doctor I'm taking senolytics?

Yes. Inform your primary care physician of all supplements. Fisetin and quercetin are natural compounds with excellent safety records, but your physician should be aware for complete medical history.
