KLOW: Quadruple Peptide Research Blend Research Use Only | ≥99% Purity
KLOW is a four-compound synthetic research peptide blend combining GHK-Cu, BPC-157, TB-500, and KPV in a single lyophilized formulation. Each component has been independently studied in laboratory settings for distinct cellular signaling properties, and their combined presence in a single formulation offers researchers a comprehensive vehicle for investigating overlapping and complementary signaling pathways in controlled in vitro and animal model research protocols.
GHK-Cu (50mg) : Glycyl-L-histidyl-L-lysine copper complex; a naturally occurring copper-binding tripeptide researched for its interactions with tissue remodeling signaling, antioxidant pathways, and gene expression regulation in laboratory models.
BPC-157 (10mg) : Body Protection Compound-157; a pentadecapeptide sequence derived from a naturally occurring gastric protein, widely studied for its interactions with growth factor signaling pathways in controlled research settings.
TB-500 (10mg) : A synthetic peptide derived from the actin-binding domain of the naturally occurring Thymosin Beta-4 protein, researched for its role in actin regulation and cellular migration pathways.
KPV (10mg) : Lysine-Proline-Valine; a C-terminal tripeptide fragment of alpha-melanocyte stimulating hormone (alpha-MSH), researched for its interactions with melanocortin receptor pathways and inflammatory signaling mechanisms in laboratory models.
All USA Made Peps KLOW is tested by an independent laboratory on every shipped lot (chromatographic purity by UPLC with area normalization, and identity by mass spectrometry); every lot we have published has tested at 99% or higher, our written guarantee is 98.0% (see the specification block), and each shipped lot is supplied with a full Certificate of Analysis.
