A plain-language, continually updated guide from Dr. Matt Chalmers’ clinical reference on hormones and peptides.
KLOW is not a single peptide. It is a combination of four peptides used together for tissue repair, skin and inflammation: KPV, BPC-157, TB-500 and GHK-Cu. Each one signals a different part of the healing process, which is why they are often combined.
Patients consider KLOW for injury recovery and tissue repair, skin, hair and collagen, gut health and inflammation, and healthy aging. Because it combines four signals in one protocol, it is used when several of these goals overlap. Whether KLOW fits your plan is decided individually by our providers after your consultation.
Repair peptides tell the body to rebuild tissue, but the body still needs the raw materials. Adequate protein and amino acids, vitamin C for collagen, copper and zinc balance, and good hydration all matter when your goal is healing.
None of the peptides in KLOW are FDA-approved as drugs, and the combination has not been studied as a single product in human clinical trials. Most of the research on its components comes from laboratory and animal studies. Active or suspected cancer is treated as a reason not to use it. This page is educational and not an offer to prescribe KLOW outside an individualized evaluation.

No. None of the peptides in KLOW are FDA-approved as drugs, and the blend has not been tested as a product in human clinical trials.
BPC-157 is one of the four peptides in KLOW. KLOW adds TB-500, GHK-Cu and KPV, so it targets cell migration, collagen and inflammation as well as tissue repair.
