Glow Blend 70mg

GLOW is a three-component lyophilized preparation supplied in a single vial and resolved by component on the certificate of analysis. GHK-Cu is the copper(II) coordination complex of the tripeptide glycyl-L-histidyl-L-lysine; BPC-157 is a synthetic pentadecapeptide of sequence Gly-Glu-Pro-Pro-Pro- Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val; TB-500 is the full-length 43-residue thymosin beta-4 sequence, which carries the LKKTETQ actin-binding motif. The three components are chemically distinct and are characterised separately.

GHK-Cu has no named receptor; its defining molecular interaction is square-planar coordination of copper(II) by the glycyl amine, the deprotonated backbone amide and the histidine imidazole nitrogen, characterised in vitro by UV-visible absorbance, circular dichroism and EPR spectroscopy, with conditional stability constants determined by potentiometric titration. For TB-500, the characterised molecular partner is monomeric G-actin; complex formation is quantified in vitro by pyrene-actin polymerisation assays, DNase I inhibition assays and isothermal titration calorimetry. For BPC-157, no high-affinity receptor has been established in the peer-reviewed literature, and in-vitro characterisation is reported at the level of defined enzymatic and immunoblot endpoints in cultured cell lysates rather than at a defined binding site.

Primary literature on the coordination chemistry of glycyl-L-histidyl-L-lysine copper(II), the actin-binding chemistry of the full-length thymosin beta-4 sequence, and the synthesis and analytical characterisation of BPC-157 is indexed in PubMed and in peptide and bioinorganic chemistry journals. Search results and cited literature do not establish the performance of a commercial lot or a use recommendation.
