KLOW is a four-component research blend combining GHK-Cu, BPC-157, TB-500, and KPV. This guide summarizes what the published scientific literature has examined about each component, their molecular profiles, and how the blend is handled in a research setting. It is written for researchers and is not medical guidance.
What is KLOW?
KLOW combines four peptides that are each studied individually in the research literature:
- GHK-Cu (CAS 49557-75-7) — copper-binding tripeptide studied in tissue-remodeling research. See our GHK-Cu research guide.
- BPC-157 (CAS 137525-51-0) — synthetic pentadecapeptide studied in soft-tissue models. See our BPC-157 research guide.
- TB-500 (CAS 77591-33-4) — fragment related to thymosin beta-4, studied in tissue-repair models.
- KPV (CAS 69630-60-0) — the C-terminal tripeptide (Lys-Pro-Val) of alpha-MSH, studied for anti-inflammatory activity.
Research-use note: This blend is supplied strictly for laboratory research. It is not an approved drug or supplement and is not for human or animal consumption. Findings below come from cell-culture and animal-model studies.
How the blend works (the mechanisms studied)
Each component is studied along a distinct pathway: GHK-Cu in extracellular-matrix and gene-expression research; BPC-157 in tendon, muscle, and gastrointestinal models; thymosin beta-4 (TB-500) as an actin-binding peptide associated with cell migration; and KPV as an anti-inflammatory tripeptide examined in intestinal-inflammation models. The blend is used to study these research pathways together.
What researchers have studied
- GHK-Cu — Pickart (2008) reviewed GHK and tissue remodeling.
- BPC-157 — Chang et al. (2011) examined tendon fibroblast outgrowth.
- Thymosin beta-4 (TB-500) — Goldstein et al. (2010) reviewed it as a tissue-repair peptide.
- KPV — Dalmasso et al. (Gastroenterology, 2008) examined PepT1-mediated KPV uptake and intestinal inflammation.
These findings describe research outcomes in laboratory models, not validated outcomes in humans.
Handling and reconstitution in the laboratory
The blend is typically supplied as a lyophilized powder for research use. Standard laboratory practice is to reconstitute it with bacteriostatic water, swirl (not shake) until dissolved, and store the reconstituted solution refrigerated (2–8 °C). The lyophilized powder is generally stored frozen and protected from light. (General lab-handling notes, not usage instructions.)
