Thymalin

Thymic peptide complex

Intramuscular 5–20 mg per injection (Russian label) Once daily for a 3–10 day course REGIONAL PRECLINICAL / CLINICAL-HISTORY

Overview

What is Thymalin?

Thymalin is a thymic peptide preparation from the Khavinson/Khavinson-adjacent immunogerontology literature. It is distinct from thymosin alpha-1 (a defined 28-mer). All catalog material is for laboratory research use only.

Key Benefits

Immune reconstitution, T-cell maturation from progenitors, modulation of pro-inflammatory cytokines, supportive use during/after immunosuppressive therapy in the originating literature.

Mechanism of Action

Papers describe immune-gerontology readouts (T-cell markers, infection models in older animals). Standardization differs from synthetic thymosin α1.
