Thymalin is a research-grade synthetic polypeptide complex modeled after the natural thymic peptide mixture originally characterized from bovine thymus by Professor Vladimir Khavinson in the 1970s. It consists of a mixture of short peptides (mainly Glu-Trp, Lys-Glu, Glu-Asp-Gly, and others <5 kDa) that share structural characteristics with thymulin and related thymic factors. Documented extensively in the scientific literature since the 1970s, it remains one of the most-studied thymic peptide complexes globally (ncbi.nlm.nih.gov; link.springer.com). This research-grade lyophilized powder is produced under strict quality controls and accompanied by full analytical documentation, making it suitable for immunology and gerontology laboratory research.
