Overview
KLOW is a 4-compound injectable peptide blend designed for people dealing with more complex healing challenges - particularly those involving immune dysregulation, chronic inflammation, gut issues, or musculoskeletal injuries. It builds on the GLOW stack (GHK-Cu + BPC-157 + TB-500) by adding KPV, a tripeptide derived from alpha-MSH (alpha-melanocyte-stimulating hormone) that has potent anti-inflammatory and immune-modulating properties. KPV is particularly well-studied for inflammatory bowel conditions, skin inflammation, and systemic immune regulation. Together, the four compounds in KLOW address tissue repair (BPC-157), systemic recovery (TB-500), collagen and skin health (GHK-Cu), and immune/inflammatory control (KPV) - making it one of the most comprehensive healing stacks available.
Key Benefits
Mechanism of Action
KLOW works through four synergistic pathways. KPV acts on melanocortin receptors (MC1R and MC3R) in immune cells and gut epithelium to suppress pro-inflammatory cytokines like TNF-alpha, IL-6, and IL-1beta - essentially turning down the volume on runaway inflammation. GHK-Cu activates over 4,000 genes involved in skin repair, collagen synthesis, and anti-inflammatory signaling. BPC-157 promotes angiogenesis, upregulates growth hormone receptors in connective tissue, and modulates nitric oxide pathways to accelerate local repair. TB-500 upregulates actin to improve cell migration and systemic recovery. The addition of KPV to the GLOW stack is what makes KLOW particularly effective for immune-related conditions and gut health.
Dosing Protocol
Typical Dose
KPV 500 mcg-1 mg + GHK-Cu 1-2 mg + BPC-157 500 mcg-1 mg + TB-500 2.5 mg per injection
Dose Range
KPV 250 mcg-2 mg | GHK-Cu 1-2 mg | BPC-157 250 mcg-1 mg | TB-500 2-5 mg
Frequency
3-5x per week (loading phase), 2-3x per week (maintenance)
Route
Subcutaneous injection; for GI conditions, oral KPV may be used alongside injectable components
Cycle Length
8-12 week cycles with 4-week breaks
CLINICAL NOTES
For inflammatory bowel conditions, some practitioners use oral KPV separately while injecting the remaining three compounds. Reconstitute each component separately unless using a pre-blended vial. Rotate injection sites. Medical supervision is strongly recommended given the immune-modulating effects of KPV.
