What is Thymalin?
Thymalin (Thymus gland polypeptide complex (natural extract)) is a Natural polypeptide complex from calf thymus. Natural polypeptide complex from calf thymus glands containing multiple immunoregulatory peptides. Promotes T-cell maturation, immune competence, and thymic hormone-like activity. Predecessor to synthetic Thymosin Alpha-1 — contains the bioactive AEDG-like components alongside other thymic factors.
