Figures are structural data from our specification and certificates, or are drawn from published third-party literature about the compound, and are provided for orientation only. Nothing here is a claim about what this material does. Supplied for laboratory research use only.
KLOW is a four-component research blend: GHK-Cu (50mg), KPV (10mg), BPC-157 (10mg) and TB-500 (10mg), documented per component on its certificate of analysis. Each component has its own published literature; no study covers the blend as a whole.
Signalling pathways examined in preclinical models. Descriptive of published research directions, not claims of effect.
Studied for how inflammation in the gut is switched off. Interest centres on the fact that KPV is only the tail end of a larger hormone, yet appears to carry the anti-inflammatory activity on its own.
Studied for skin remodelling and wound closure, centred on its ability to hold a copper ion that several of the enzymes rebuilding skin require.
Studied for how connective tissue, tendon in particular, recovers after injury.
Studied for its role in how cells move and reorganise their internal scaffolding, the process underlying wound closure and tissue remodelling.
Reduced across both independent models.
Isolated from human plasma as a naturally occurring factor affecting how cells grow.
Tendon tissue grew outward faster in the source work.
The parent protein was established as a major regulator of the cell's actin supply.
Reference class characteristics for orientation. Half-life figures are typical literature values, not lot measurements.

This material is supplied as a reference standard for in-vitro laboratory research only. It has not been evaluated by the FDA, is not a drug, and is not intended for human or veterinary use. Handling should follow your institution's chemical hygiene plan, including appropriate PPE and documented disposal.
Each component is documented separately at 99%+ by RP-HPLC with identity confirmed by LC-MS. Released lots have measured between 99.613% and 99.76%. The certificate reports measured content for all four peptides individually rather than a single blended figure.
Yes. Every lot ships with its own signed certificate, and all three are published in the COA library, including for lots no longer in stock.
A single 80mg vial — GHK-Cu 50mg plus KPV 10mg plus BPC-157 10mg plus TB-500 10mg.
There is no single sequence for a blend. It contains GHK-Cu (Gly-His-Lys with copper(II), three residues), KPV (Lys-Pro-Val, three residues), BPC-157 (GEPPPGKPADDAGLV, fifteen residues) and TB-500 (Ac-LKKTETQ, seven residues), which is why the formula, weight and CAS fields read per component and the certificate carries the per-component figures instead.
GHK-Cu at 50mg, KPV at 10mg, BPC-157 at 10mg and TB-500 at 10mg, for an 80mg total fill. Measured content per lot is in the certificate table above.
KLOW is GLOW plus KPV. GLOW carries GHK-Cu, BPC-157 and TB-500; KLOW adds KPV, a tripeptide studied in gut inflammation models, taking the fill from 70mg to 80mg.
No. Each of the four components has its own published preclinical literature, but no study covers this combination. The research directions above belong to the individual peptides.
Store the sealed vial at −20°C for long-term stability and 2–8°C for short-term handling. Protect from light and avoid repeated freeze-thaw cycles. Compound-specific stability data is printed on the certificate of analysis supplied with the lot.
