KLOW is a four-peptide research blend combining GHK-Cu, BPC-157, TB-500 and the tripeptide KPV, supplied as a lyophilised powder. It is supplied strictly for laboratory research use only.

What research area is KLOW Blend associated with?

Published preclinical laboratory work in this class concerns copper-transport, actin-binding and melanocortin-fragment signalling chemistry in vitro. We supply the material only; we make no representation as to any outcome, effect, or suitability for any purpose.

Is KLOW Blend approved for human use?

No. KLOW Blend is not a drug, supplement, food, cosmetic, or medical device, and has no approved human or veterinary indication. It is sold strictly for in-vitro laboratory research use by qualified professionals.

What purity is KLOW Blend supplied at, and how is it verified?

Each lot is assayed by HPLC and ships with its own lot-specific Certificate of Analysis, published in our COA registry. Purity figures are stated per lot - we do not publish a brand-wide specification in place of the actual certificate.

Proof, not promises. Every batch, tested by an outside lab.

Every batch of KLOW Blend is tested by an outside lab before it goes on sale — not by us. The one shipping now is lot 29UTZY: 99.78% pure by HPLC, tested by Freedom Diagnostics on 19 Oct 2026. The signed report is right here. Purity is the number the lab measured, never “at least 99” — and a batch that misses its spec never ships.

How KLOW Blend works

A multi-peptide blend studied for touching gene activity, repair and inflammation together.

Gene expressionGHK-Cu

Studied for GHK-Cu shifting human genes toward younger expression patterns.

Anti-inflammatoryKPV

Investigated for KPV easing inflammatory signalling without broad immune suppression.

Tissue repairBPC-157 / TB-500

Researched for the repair and cell-migration signalling contributed by BPC-157 and TB-500.

For research use only. Mechanisms described reflect published research literature.

What the studies found

Published findings on this compound, each linked to its source. Animal and lab results are context, not claims about this product.

Younger gene activityPreclinical

4,000+

In gene-expression analyses, GHK has been reported to shift the activity of at least 4,000 human genes, many of them toward a more youthful pattern.

Inflammation signalsPreclinical

KPV entered gut-lining cells through the PepT1 transporter and reduced inflammatory signalling in human intestinal and immune cells and in two mouse colitis models.
