Four peptides side by side in one vial: BPC-157, GHK-Cu, TB-500 and KPV. That makes KLOW the extended sibling of the well-known GLOW blend, with KPV as the added component. Each of the four is studied separately in research, around repair, tissue, inflammation and skin; here they sit together in fixed ratios. We supply the combination ready-made as a research-grade vial at ≥99% HPLC purity, dispatched the same working day from the Netherlands.
Why this blend gets picked so often
That KLOW ranks among the most popular blends has a simple reason: four peptides that all turn on repair and tissue sit here in one vial. Instead of placing four separate compounds side by side, you work with one balanced mix. The components are thought to complement one another across tissue repair, inflammation and skin. Researchers therefore use the blend to study that combined route. At BasePurity you buy it purely as a research raw material, not for use in humans.
The four components at a glance
One 80 mg vial holds four peptides in fixed ratios. BPC-157 is known from research around the repair of connective tissue and the gut lining. GHK-Cu is the copper peptide studied around collagen, skin and cell renewal, and makes up by far the largest share of the mix. TB-500, the research fragment of thymosin beta-4, is tied to cell migration and to the repair of muscle, tendon and ligament. KPV, finally, is a small anti-inflammatory peptide, the tail end of α-MSH. If you would rather study one on its own, all four also sit separately in the range; the exact ratios are listed under the ingredients.
The difference from GLOW
Online you will run into two names that differ by a single letter. GLOW is the three-part blend of BPC-157, GHK-Cu and TB-500. KLOW is that exact base with KPV added, and that fourth component brings in the anti-inflammatory side. In short, KLOW is GLOW plus KPV. We carry the four-part version; if you want the three-part one, you build it yourself from the separate components.
Four sides of the same theme
The thinking behind the blend is that each peptide covers a different corner of the same subject. BPC-157 and TB-500 are tied mainly to tissue and muscle repair, GHK-Cu to skin, collagen and cell renewal, and KPV to dampening inflammatory signals. The four together are thought to give a broader picture than a single peptide alone. Most of what is known about this comes from studies on the individual components.
Converting the blend as a whole
We deliberately leave the amount open: this is a research compound, and we give no human dosing advice with it. In the literature the individual components are studied per protocol in small amounts, after dissolving with bacteriostatic water. Because the ratios in the vial are fixed, you convert not per component but the blend as a whole; our calculator is ready for that. Keep the dissolved peptide refrigerated and use it within the recommended window.
Which reactions are reported?
The individual components are each known in research for a mild profile; studies mostly note mild reactions, such as irritation at the injection site. Little is yet known about the blend as a whole, since four peptides are in play at once, and large-scale long-term data in humans is lacking.
The legal side
In the Netherlands you may buy and sell this blend for experimental laboratory research that is not applied to humans or animals. An approved medicine it is not: these are four research peptides, and nowhere is the combination prescribed for human use. For athletes it matters that several of these peptides are on the WADA prohibited list and so banned in competitive sport. We supply strictly as a research-grade compound.
Four components, four checks
With a blend of four peptides, purity counts all the more, because every component has to be right. Every batch therefore goes through HPLC for ≥99% purity and for identity, with a certificate of analysis per lot, and leaves freeze-dried so it reaches you stable. The full specifications are in the table at the bottom of this page.
