Naples Laser & Skin

Composition Profile

Klow Blend
Multi-peptide research compound

GHK-Cu	Copper-binding tripeptide Gly-His-Lys; typically the largest share by mass (e.g. 50 mg of an 80 mg vial)
BPC-157	Synthetic 15-amino-acid peptide, a fragment derived from a gastric protective protein
TB-500	Synthetic fragment corresponding to Thymosin Beta-4, an actin-regulating peptide
KPV	Tripeptide Lys-Pro-Val derived from the C-terminal sequence of alpha-MSH; the addition that distinguishes Klow from the base Glow blend
Typical form	Lyophilized (freeze-dried) powder in a multi-dose vial, reconstituted with bacteriostatic water before use
Vendor labeling	Almost universally sold as "for laboratory / research use only, not for human consumption"

HOW IT WORKS

Klow carries the same three claimed mechanisms as Glow — collagen/skin signaling (GHK-Cu), soft-tissue and gastric repair (BPC-157), and cell migration/angiogenesis (TB-500) — plus a fourth: KPV is marketed for anti-inflammatory signaling via NF-κB and cytokine modulation, positioned as adding an "inflammation control" layer on top of the other three's repair mechanisms. As with Glow, these claims rest almost entirely on in vitro and animal studies, not human trials of the combined blend.

WHAT TO EXPECT

Sold online through peptide/"research chemical" vendors, not pharmacies
Marketed as an extension/upgrade of the three-peptide Glow blend
Each individual component studied preclinically; the four-peptide combination itself is not

BEFORE YOU START

Differs from Glow by exactly one added peptide (KPV) — same base three-peptide backbone (GHK-Cu, BPC-157, TB-500)
KPV is the least-studied component of the four in human contexts, derived from a hormone fragment rather than a repair-signaling molecule like its blend-mates
Purity, dosing accuracy, and sterility vary by vendor and are not independently regulated the way pharmacy-dispensed drugs are
