Immune SupportAnti-Aging & Longevity
Thymosin Alpha-1
Summary
KPV is a naturally occurring anti-inflammatory tripeptide derived from the C-terminal of alpha-MSH. It powerfully suppresses intestinal and systemic inflammation via melanocortin receptors, making it valuable for IBD, gut healing, and wound repair.
Thymosin Alpha-1 is a naturally occurring 28-amino acid peptide derived from the thymus gland. It is a powerful immune modulator approved in many countries for treating chronic hepatitis B, hepatitis C, and as an adjunct in cancer immunotherapy.
Half-Life
Short half-life (~15–30 minutes), but effects persist longer due to receptor-level anti-inflammatory cascades
