BPC-157 and KPV are compared because both are studied in gut-related research. BPC-157 is a synthetic 15-amino-acid peptide derived from a protein in human gastric juice, studied for tissue repair. KPV is a three-amino-acid fragment from the end of alpha-melanocyte-stimulating hormone (alpha-MSH), studied for anti-inflammatory activity. Neither is FDA-approved.
At a glance
| BPC-157 | KPV | |
|---|---|---|
| What it is | Synthetic 15-amino-acid peptide from human gastric juice, studied for tissue repair and gut healing | Tripeptide (lysine-proline-valine) from the end of alpha-MSH, studied for anti-inflammatory activity in the gut and skin |
| How it's thought to work | Studied for enhancing fibroblast activity, collagen synthesis, angiogenesis, and growth factor activity; also dopamine and serotonin systems | Studied for entering cells and reducing NF-kB inflammatory signaling, without the pigmentation activity of full alpha-MSH |
| Regulatory status | FDA Category 2 substance; WADA prohibited; not FDA-approved for any human use | Not FDA-approved for any human use; sold only as a research chemical |
| Strength of evidence | Extensive preclinical (animal and lab) data; human clinical trials remain limited | Preclinical (animal and lab) studies in colitis and skin inflammation; human clinical data is limited |
| Reported side effects | Minimal: occasional injection site redness or irritation, rare mild dizziness or nausea | Minimal; occasional injection site irritation. Long-term human safety data is limited |
| Common vial sizes | 5mg, 10mg | 5mg, 10mg |
| Mixing math example | 5 mg + 1 mL BAC water = 5,000 mcg/mL, 50 mcg per unit | 5 mg + 1 mL BAC water = 5,000 mcg/mL, 50 mcg per unit |
Key differences
BPC-157 is studied for enhancing fibroblast activity, collagen synthesis, angiogenesis and growth factor activity. KPV is studied for entering cells and reducing pro-inflammatory signaling through the NF-kB pathway, keeping the anti-inflammatory core of alpha-MSH without its pigmentation activity.
BPC-157 is an FDA Category 2 substance and is on the World Anti-Doping Agency's prohibited list. KPV is not FDA-approved for any human use and is sold only as a research chemical.
Both have minimal reported side effects, mainly injection site irritation. For KPV, long-term human safety data is limited.
What the research covers
Both evidence bases are mainly preclinical. BPC-157 has extensive animal and laboratory research on tissue repair with limited human trials. KPV's anti-inflammatory findings come from animal models of colitis and skin inflammation, and human clinical data is limited.
