Immune restoration
Anti-aging
Thymus function
T-cell regulation
Thymalin is a polypeptide extract of the thymus gland used extensively in Russian longevity research. It restores thymic function, improves T-cell immunity, reduces all-cause mortality in clinical trials, and has shown remarkable effects on aging biomarkers. Russian studies with 10-day courses showed significant increases in longevity.
Mild injection site reactions
Transient fatigue
Generally very well tolerated
Using oral preparations instead of IM injection — Thymalin requires intramuscular injection; oral preparations are not bioavailable
Running it continuously instead of in 10-day cycles — all the published Russian research used the intensive cycle protocol
Not combining with Epithalon — the combined longevity outcomes consistently outperform either compound alone
Immunosuppressants — directly antagonistic to Thymalin's immune-restoring effects; avoid in transplant patients
Corticosteroids — reduce thymic output and may blunt Thymalin's immune restoration
No known adverse drug interactions at standard research doses
Thymalin is the most studied peptide longevity compound in existence via Russian bioregulator research, yet nearly unknown in Western markets. The 10-day cycle twice yearly protocol showed significant reductions in all-cause mortality in clinical studies. Combined with Epithalon, it's the most evidence-backed longevity peptide stack available anywhere.
