Your protocol

How KLOW Blend is prescribed.

Who it's for
  • Adults who want a broad recovery and skin-support blend in one vial
  • Patients managing inflammation across more than one area
  • People combining recovery goals with skin or collagen goals

Your physician decides whether KLOW Blend is appropriate for you after reviewing your intake and labs.

Directions & duration

Inject 0.25 mL (25 units) subcutaneously Monday through Friday mornings.

Cycle. Ongoing monthly treatment. Most patients notice the most change in the first two months and continue for lasting support.
Ready for more? When you're ready for more, ask your physician to double your dose. If approved, the extra vial is billed at cost and applied to your next fill.
Directions shown are the pharmacy's standard for this preparation. Your prescription label is the final word.

The science

How KLOW Blend works, and what the research shows.

How it works

KLOW combines four peptides — GHK-Cu, KPV, BPC-157, and TB-500 — into a single vial.

Each targets a different stage of the repair cascade: KPV controls inflammation, BPC-157 stimulates angiogenesis, TB-500 mobilizes cell migration, and GHK-Cu drives collagen synthesis.

Clinical evidence
  • The blend's components are individually studied: GHK-Cu has decades of dermatologic research on collagen synthesis and wound repair, BPC-157 and TB-500 have extensive preclinical tissue-repair literature, and KPV has shown anti-inflammatory effects in preclinical gut-inflammation models.

    Maquart et al., FEBS Lett 1988; Pickart & Margolina 2018
  • The four-peptide combination itself has not been evaluated in human trials; physicians prescribe it based on the component evidence.
