What is it—and why does it matter?
Thymalin is presented as a peptide bioregulator derived from (or associated with) the thymus (i.e., a thymic peptide regulator). A distinct cohort receiving combined Thymalin and Epithalamin annually over 6 years is reported to have a 4.1-times lower mortality rate than control.
