Research in plain language

KLOW

This product combines several research peptides. There are no separate studies on the blend itself; below is the published research for each component.

Components

GHK-CuGHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine, a small peptide that occurs naturally in human plasma, saliva, and urine and declines with age. It has been studied mostly in cell culture and animals as a signal that can stimulate collagen and growth-factor production by fibroblasts, support wound healing and angiogenesis, and reduce oxidative-stress and inflammatory markers.BPC-157BPC-157 is a synthetic stable gastric pentadecapeptide (15 amino acids), a fragment derived from a protein found in human gastric juice. In animal studies it has been tested for its effect on healing of tendon, ligament, muscle-tendon junction, nerve, and the stomach lining. All efficacy evidence to date is preclinical (rats); there is no published human efficacy trial and no established human dosing protocol.TB-500Thymosin beta-4 (Tbeta4) is a naturally occurring 43-amino-acid actin-sequestering peptide. In research it has been studied for tissue repair: dermal and corneal wound healing, cardiac protection after a heart attack, and dry eye. The clinical and animal-study evidence is built almost entirely on the full-length 43-amino-acid peptide (drug codes RGN-259 for the eye and RGN-352 for systemic/cardiac use). "TB-500" is the common research-market name for this peptide, and the material we supply is the full-length 43-amino-acid thymosin beta-4 (mass ~4963 Da, CAS 77591-33-4), independently confirmed by our third-party CoA: the same molecule used in the studies below. (The name "TB-500" is also sometimes used for a short Ac-LKKTETQ fragment, so a CoA matters; ours certifies the full 43-aa form.)KPVKPV is the C-terminal tripeptide of alpha-melanocyte-stimulating hormone (lysine-proline-valine, also called alpha-MSH 11-13). It is studied mainly as an anti-inflammatory agent: in cells and in mouse models of intestinal inflammation (DSS- and TNBS-induced colitis, a stand-in for inflammatory bowel disease) it dampens inflammatory signalling (NF-kB and MAP kinase pathways) and reduces tissue inflammation markers. Evidence is almost entirely in-vitro and in mice; there are no published human efficacy trials.
