Bottom line
A two-component research-peptide combination pairing BPC-157 (cytoprotective/angiogenic pentadecapeptide) with KPV (Lys-Pro-Val, anti-inflammatory tripeptide derived from alpha-MSH). Often marketed as a GI-focused alternative to broader blends, and as a component of KLOW70 (which adds GHK-Cu without TB-500). No published combination study exists.
No established or recommended human dose.
Name and formulation variability
| Market context | Claimed composition | Claimed amounts | Verification limits |
|---|---|---|---|
| Marketed pair | BPC-157, KPV | Common listing: 10 / 10 mg | Seller-dependent; no formulation standard |
| KLOW70 observation | BPC-157, KPV, plus GHK-Cu | Observed listing: 10 / 10 / 50 mg | Seller-declared; not the same composition as the standalone pair |
This combination exists as a distinct pairing (especially in GI research contexts) or as KLOW70 (which adds GHK-Cu but omits TB-500). Composition varies.
Component evidence
| Component | Separate evidence | Combination evidence | Compatibility |
|---|---|---|---|
| BPC-157 | Evidence from in vitro or animal studies with no adequate human efficacy evidence — the atlas Grade D lane. Source de la définition: Evidence grading methodology · Glossaire stage: GI and repair models, VEGFR2/NO and nitric-oxide pathway hypotheses | Not identified for the pair; see shared caption below | No co-formulation stability data |
| KPV | Identity and preclinical stage: Lys-Pro-Val, an alpha-MSH C-terminal fragment; inflammation models and PepT1 transport findings, including the Dalmasso 2008 colitis-model results | Not identified for the pair; see shared caption below | Interaction and co-formulation evidence not identified |
Shared combination-evidence caption: these are separate preclinical domains. They do not establish combined efficacy, safety, or compatibility.
BPC-157 has separate evidence in GI models, repair models, and pathway hypotheses. KPV has a defined alpha-MSH fragment identity plus separate inflammation-model and transport findings. The labels meet only as a marketed pairing; efficacy and safety were not tested as a pair.
Combination-specific studies
No published study tests the BPC-157 + KPV combination. The rationale rests entirely on separate component evidence.
Safety and interaction uncertainties
KPV's NF-κB inhibition may theoretically delay resolution-phase inflammation
BPC-157's NO modulation may interact with anti-inflammatory pathways
No combination-specific safety data
Fixed-ratio blends prevent independent dose adjustment
Regulatory and product-quality notes
Neither component is FDA-approved
Both sold as "research use only"
KPV occasionally appears in cosmetic products
The World Anti-Doping Agency; its Prohibited List classifies many peptides as prohibited substances in sport. Source de la définition: WADA and sport regulation brief · Glossaire: BPC-157 is listed under S0. KPV is not explicitly named in the 2026 List; an athlete should obtain a case-specific determination rather than infer status from the blend or from KPV's peptide class.
Evidence gaps
No combination study of any kind
No co-stability data
No How a substance is absorbed, distributed, metabolized, and eliminated by the body; atlas pages report pharmacokinetic data such as half-life, metabolism, and clearance. Source de la définition: Neutral gloss; usage context: Routes, devices, and absorption primer · Glossaire interaction data
No dose-ratio optimisation
No human data for either component for GI repair claims
The KLOW70 analysis covers the observed three-component name without conflating it with this pair. For sample-level verification limits, see Product quality, authenticity, and testing.
