KLOW Blend at a glance

KLOW is a fixed combination product rather than a new molecule. Each 80 mg vial holds four separately studied peptides: 10 mg BPC-157, 50 mg GHK-Cu, 10 mg TB-500 and 10 mg KPV. The name builds on GLOW, the three-peptide mix without KPV. Because the components keep their own structures, the blend is best described in terms of its parts, and the copper carried by GHK-Cu can give the powder a faint blue color.

Price and availability

A kit of 10 vials at 80mg each (800 mg in total) from BioPepta, shipped from China. $170.00 buys the whole kit, which is $0.212/mg. Of the 10 KLOW Blend listings on the marketplace, from 10 brands, this is the 2nd-lowest price per mg. Checkout goes into escrow first; the funds move to BioPepta once delivery is confirmed.

What it is studied for

Each component brings its own research profile. BPC-157, a stable fragment derived from a gastric protein, is studied in tendon, gut and blood-vessel models. GHK-Cu, a copper-binding tripeptide, is investigated for effects on collagen production and the expression of genes involved in tissue remodeling. TB-500 regulates actin and is associated with cell migration in repair studies. KPV, a short fragment of alpha-MSH, is examined for dampening inflammatory signaling through the NF-kB pathway. Combining them in one vial does not by itself establish any interaction between them.

Research and regulatory status

There is a preclinical literature for each peptide on its own, covering skin and wound models, gut inflammation, connective tissue and cell culture. The four-way combination, however, has not been studied as a formulation in controlled experiments, so any conclusions about KLOW as a whole are extrapolated from single-agent work. None of the components is an approved medicine for human use, and the blend has no regulatory status beyond research material.

Checking the lab data

A credible KLOW report identifies all four peptides separately. Expect mass spectrometry confirming BPC-157, GHK-Cu, TB-500 and KPV at their expected masses, and an HPLC trace in which each component is resolved and quantified against the stated 10/50/10/10 mg split. A single overall purity number is not enough for a blend. The cake may carry a pale blue tint from the copper complex; dark or patchy discoloration is worth questioning.

Storage and preparation

Freeze-dried peptide keeps best sealed, cold and dark. Once it has been dissolved, refrigerate it, avoid repeated warming and follow the stability limits in your study protocol.

Concentration arithmetic: one 80 mg vial dissolved in 2 mL gives 40 mg/mL, or 80 mg/mL in 1 mL. The Research Lab calculator in your dashboard handles any other volume.

Buyer questions

Why would a researcher choose a blend over separate vials?

Mainly convenience and a fixed ratio. A combined vial means one preparation instead of four, and the proportion of each peptide is set by the manufacturer. The trade-off is flexibility: the ratio cannot be adjusted, and if one component degrades or is underfilled, the whole vial is affected, which makes component-level testing important.

Is there research on the four peptides used together?

Not in a controlled, published form that we are aware of. Each peptide has its own preclinical literature, and the blend is a commercial combination of those individually studied materials. Claims that the four work better together are not supported by direct evidence, so the combination should be treated as a convenience format.

How much KLOW Blend is in this listing?

10 vials of 80mg each — 800 mg in all. Where a lab report exists, the testing panel above shows what the brand's tested sample actually measured.

When does BioPepta get paid?

Only after you confirm delivery. Until then the payment is held in escrow, and you can open a claim if anything is wrong with the order.
