Glow Blend

Glow Blend is Signal Labs' comprehensive three-component tissue biology research preparation containing BPC-157 (10mg), TB-500 (10mg), and GHK-Cu (50mg) co-lyophilised in a single vial. Each component is independently HPLC-verified to greater than or equal to 98% purity before combination. The preparation provides simultaneous coverage of three mechanistically distinct but complementary biological pathways — nitric oxide and VEGF-mediated vascular signalling, actin cytoskeletal dynamics and cell migration, and copper-dependent extracellular matrix biology — in a single reconstitution.

BPC-157 (Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val, MW 1419.56 g/mol, 10mg per vial) contributes eNOS/NO signalling, VEGF and EGR-1 expression changes, FAK-paxillin pathway modulation, and gastrointestinal cytoprotection biology to the preparation. The triple-proline sequence at positions 3-5 forms a polyproline II helix providing exceptional protease resistance — BPC-157 maintains activity in biological media where most peptides would be rapidly degraded. Over 100 peer-reviewed publications document BPC-157 biology across gastrointestinal, musculoskeletal, neurological, and vascular research contexts.

TB-500 (synthetic Thymosin Beta-4, 43 amino acids, MW 4963.5 g/mol, 10mg per vial) contributes G-actin sequestration through the LKKTET hexapeptide motif, regulating the G/F-actin equilibrium and driving lamellipodia-dependent cell migration. TB-500 also activates integrin-linked kinase (ILK) through a second, actin-independent mechanism connecting it to PI3K/Akt cell survival signalling. Published research in cardiac biology (Smart et al., Nature, 2007) established Thymosin Beta-4 as a mediator of epicardial progenitor cell mobilisation — connecting TB-500 to cardiac tissue research beyond wound healing.

GHK-Cu (Glycine-Histidine-Lysine copper complex, MW 403.45 g/mol, 50mg per vial) contributes copper-dependent biology: stimulation of collagen type I, III, and IV synthesis in fibroblast models; regulation of MMP/TIMP balance through SP1-mediated transcription; antioxidant signalling; and broad gene expression effects documented by Pickart and Margolina (IJMS, 2018) spanning several thousand differentially expressed genes in treated fibroblast models. The higher GHK-Cu mass (50mg versus 10mg for each peptide) reflects the compound's much lower molecular weight — at 50mg GHK-Cu provides approximately 124 nmol, comparable on a molar basis to the 7 nmol BPC-157 and 2 nmol TB-500 from their respective 10mg masses.

The GHK-Cu component produces the preparation's characteristic blue-green colour upon reconstitution — a quality indicator confirming correct copper coordination. A clear, colourless reconstituted Glow Blend solution would indicate GHK-Cu copper loss and should not be used for research.

Research requiring mechanistic dissection of individual component contributions should use the separately available individual products: BPC-157 (10mg), TB-500 (10mg), GHK-Cu (50mg, 100mg). The BPC+TB Blend (without GHK-Cu) covers the two peptide mechanisms for research where copper biology is not required. Full factorial experimental design (vehicle, BPC-157 alone, TB-500 alone, GHK-Cu alone, pairwise combinations, full Glow Blend) enables rigorous attribution of any observed effects to individual pathway contributions and identification of additive versus synergistic interactions.

Total vial content: 70mg (10mg BPC-157 + 10mg TB-500 + 50mg GHK-Cu). Reconstitute in bacteriostatic water. Avoid reducing agents (DTT, BME, TCEP) which would disrupt the GHK-Cu coordination. Store lyophilised at -20°C. For laboratory and analytical research purposes only.

Reconstitution protocol: add bacteriostatic water to the lyophilised powder; the GHK-Cu component will produce the characteristic blue-green colour confirming correct copper coordination. A clear, colourless reconstituted solution indicates GHK-Cu copper loss and should not be used. Avoid reducing agents (DTT, BME, TCEP) which disrupt GHK-Cu coordination. At the 10:10:50mg ratio, the molar content of each component is: BPC-157 approximately 7 nmol, TB-500 approximately 2 nmol, GHK-Cu approximately 124 nmol. Total vial: 70mg. Store lyophilised at -20°C. For laboratory and analytical research purposes only.
