KGLOW (also spelled KLOW) is four popular peptides blended into one vial, so you don’t need to buy them separately. One 80 mg vial contains GHK-Cu (50 mg), BPC-157 (10 mg), TB-500 (10 mg) and KPV (10 mg). As a majority copper-peptide preparation it develops a blue colour, must not contact acidic liquid or a chelating agent, and is best kept in the dark.
KGLOW, supplied to Canadian researchers by Popular Peptides. One 80 mg vial, ≥98% purity. Tested by an independent lab for purity and content (HPLC); the lab report (COA) for your batch is available on request. Ships tracked and insured from Vancouver by Canada Post Xpresspost, usually 1 to 4 business days, with no customs step and no brokerage fee.
Sold as a laboratory research material only, for in vitro use. It isn’t a medicine and isn’t meant for people or animals.

KGLOW — compound background
Four-component dermal research blend — GHK-Cu 50 mg / BPC-157 10 mg / TB-500 10 mg / KPV 10 mg (80 mg total)
KGLOW is GLOW with a fourth component added: KPV, a tripeptide (Lys-Pro-Val) corresponding to the C-terminal fragment of alpha-melanocyte-stimulating hormone. The other three amounts are unchanged — GHK-Cu 50 mg, BPC-157 10 mg, TB-500 10 mg — with KPV at 10 mg bringing the vial to 80 mg. KPV is studied primarily for anti-inflammatory activity in preclinical models, notably retaining that property of the parent hormone without its pigmentation-related effects.
Solubility & reconstitution
All four components are freely water-soluble and reconstitute together. As with GLOW the solution is blue, since GHK-Cu is still the majority component at 62.5% by mass. KPV is very small and highly water-soluble, adding no dissolution difficulty. The same pH constraint applies: never use acidic diluent, because it dissociates copper from the GHK-Cu component.
An 80 mg vial in 3 mL gives roughly 27 mg/mL combined (≈16.7 mg/mL GHK-Cu, 3.3 mg/mL each of the other three).
Storage
Sealed at -20 °C, dry and dark. Refrigerate at 2–8 °C, protected from light — driven by the TB-500 methionine and the photo-reactive GHK-Cu copper complex.
Commonly worked with for 2–3 weeks at 2–8 °C, set by the TB-500 and GHK-Cu components.
Stability
Adding KPV does not change the handling profile. GHK-Cu still dominates and still dictates the rules: neutral pH, no chelators, light protection.
Reading the Certificate of Analysis
A meaningful KGLOW COA resolves all four components with a stated ratio approximating 50:10:10:10 by mass. Copper content should be confirmed separately for the GHK-Cu component. KPV is small and elutes early on RP-HPLC, so confirm the method actually resolves it rather than losing it near the solvent front.
