KPV peptides have gained attention for their anti-inflammatory and tissue-protective properties in various experimental models. Despite promising therapeutic potential, there are documented concerns regarding hepatic safety that warrant careful consideration by researchers and clinicians alike.



Liver-related side effects associated with KPV peptide administration include transient elevations of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), indicative of mild hepatocellular stress. In rodent studies, repeated dosing at concentrations above 10 µg/kg per day led to histopathological changes such as fatty infiltration and periportal inflammation. Human case reports are sparse but have noted mild jaundice and pruritus in individuals who self-administered KPV without medical supervision. The mechanism is thought to involve off-target interaction with hepatic G protein–coupled receptors, leading to altered bile acid metabolism and oxidative stress within hepatocytes.



Patients exhibiting signs of liver dysfunction should discontinue use immediately and undergo comprehensive evaluation. Baseline liver function tests are recommended before initiating therapy, with periodic monitoring every four weeks for the first three months. If ALT or AST rise above twice the upper limit of normal, dose reduction or cessation may be necessary. In severe cases, imaging studies such as ultrasound or MRI can assess for steatosis or cholestasis, and a liver biopsy may be indicated to rule out other etiologies.

BPC-157, often referred to as the "Body Protection Compound," has been studied for its regenerative properties in muscle, tendon, ligament, and gastrointestinal tissues. While BPC-157 is generally well tolerated, it too can influence liver function. Clinical observations have reported mild increases in serum bilirubin and alkaline phosphatase after prolonged high-dose administration, suggesting a potential impact on bile flow. In animal models, hepatic steatosis was noted at doses exceeding 20 µg/kg per day over several weeks, though these effects were reversible upon discontinuation.



The therapeutic window for BPC-157 appears to be dose-dependent; lower concentrations (≤5 µg/kg/day) have not produced significant liver enzyme alterations in preclinical trials. Nevertheless, patients with preexisting hepatic conditions should exercise caution and consult their healthcare provider before starting therapy. Regular monitoring of liver enzymes is advisable, especially during the initial treatment period.



In summary, both KPV peptides and BPC-157 demonstrate potential hepatotoxicity at higher or prolonged doses. Vigilant monitoring of liver function tests, adherence to recommended dosing regimens, and prompt reporting of adverse events are essential strategies for minimizing hepatic risks while exploring the clinical benefits of these compounds.
