Key Findings
- Thymalin intensifies fibrin polymerization (promotes clot formation)
- Other regulatory peptides like interleukin‑1 and thymoptin break down fibrin and increase fibrinolysis
- Diphen‑sin infusion blocks fibrinolysis, while repeated thymoptin boosts fibrinolytic activity in rats
Practical Outcomes
- There’s no actionable protocol for biohackers; thymalin could increase clot risk rather than aid health, so it’s not recommended for routine use without medical supervision.
Summary
The study found that the peptide thymalin speeds up the formation of fibrin clots, meaning it may promote blood clotting, but it doesn’t show any clear health‑boosting benefits for longevity or performance.
Abstract
It is shown that preparations of regulatory peptides (RP): interleukin-1, thymoptin, and the endogenous nonpeptide opioid salsalinol produce a marked depolymerization effect on the fibrin-monomer and display nonenzymatic fibrinolytic activity in relation to unstabilized fibrin. Preparations of regulatory peptides thymalin and diphensin of rabbits intensify fibrin polymerization. A single intravenous infusion of diphensin preparation inhibits nonenzymatic fibrinolysis of blood plasma in vivo and in vitro. Repeated intramuscular injections of the immunoactive preparation thymoptin intensify the fibrinolytic properties of blood plasma in rats.
