Sermorelin- 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.
- Sermorelin is a bioidentical synthetic peptide comprising the first 29 amino acids of naturally occurring GHRH. It is FDA-approved for diagnostic use and widely prescribed off-label for anti-aging, stimulating growth hormone production in a natural pulsatile pattern that mimics the body's own rhythm.
- Half-Life
- Short half-life (~15–30 minutes), but effects persist longer due to receptor-level anti-inflammatory cascades
- 10–20 minutes
