Thymopentin (TP-5)

Synthetic 5-residue active fragment of thymopoietin — pharmaceutical-grade immune modulator.

TP-5 is the five-amino-acid active core of thymopoietin, another thymic hormone — the smallest piece that still carries the immune-signalling effect. It's a pharmaceutical-grade immunomodulator used clinically for conditions where the immune system is misfiring or worn down: rheumatoid arthritis, severe eczema, chronic infection. More targeted and clinical in feel than the broad "tune-up" peptides — reached for when there's a specific immune dysfunction to correct.
