Immune Support Peptides

Cathelicidin

The only human cathelicidin antimicrobial peptide, naturally produced by immune cells as a first-line defense. Has broad-spectrum antimicrobial, wound healing, and immunomodulatory properties.

Thymus polypeptide complex

A polypeptide complex extracted from calf thymus gland that broadly modulates immune function. Distinct from Thymosin Alpha-1 (a single purified peptide), Thymalin is a complex mixture of thymic peptides. Russian clinical trials show 2-2.4x reduction in acute respiratory infections and significant mortality reduction in elderly patients.

Tα1

A 28-amino acid peptide naturally produced by the thymus gland that modulates both innate and adaptive immunity. Approved under the name Zadaxin in some countries for hepatitis B, C, and as a vaccine adjuvant.

FTS

The only true thymic hormone (not a thymosin). A zinc-dependent nonapeptide naturally produced by thymic epithelial cells that directly matures T-lymphocytes. Levels decline ~90% between ages 20-60, making it a key driver of immunosenescence. Requires zinc coordination to be biologically active. Distinct from Thymalin (polypeptide extract) and Thymosin Alpha-1.
