GLOW

Each GLOW vial contains 70mg of lyophilised powder made up of BPC-157 10mg (pentadecapeptide GEPPPGKPADDAGLV, 1419.53 g/mol), TB-500 10mg (thymosin beta 4, 43 residues, 4963.4 g/mol) and GHK-Cu 50mg (glycyl-L-histidyl-L-lysine copper(II) complex, 403.9 g/mol). The current batch is UKPL-262, with a per-component content assay against a 98.0% specification published on the product page.

One vial. Some suppliers sell GLOW as a kit of five or six separate vials that the researcher reconstitutes and combines individually; the material here is a single pre-blended vial containing all three components co-lyophilised, so there is one reconstitution step and one container to store and label. That is a product format difference rather than a chemical one. The trade-off runs the other way for anyone who needs independent control of each component's concentration, which a blend cannot give.

No. There is no published in-vitro or in-vivo study of BPC-157, TB-500 and GHK-Cu co-administered together, at this ratio or any other, and no synergy between the three has been demonstrated. Every mechanistic finding cited for a glow stack comes from work on one component in isolation. Researchers should treat the blend as three separate compounds in one container and design controls accordingly, rather than assuming combined behaviour that has not been tested.

Individually, and only individually. BPC-157 is studied for local angiogenic signalling, Hsieh et al. (J Mol Med, 2017, PMID 27847966) reported VEGFR2 upregulation and receptor internalisation in human endothelial cells, and Chang et al. (J Appl Physiol, 2011, PMID 21030672) reported FAK and paxillin phosphorylation in cultured rat tendon fibroblasts. TB-500 is thymosin beta 4 and is studied for G-actin sequestration and cell motility, with Philp et al. (FASEB J, 2003, PMID 14500546) showing the LKKTETQ site alone promotes endothelial migration and Bock-Marquette et al. (Nature, 2004, PMID 15565145) reporting integrin-linked kinase and Akt activation. GHK-Cu is studied as a copper delivery ligand and matrikine, with Pickart et al. (Nature, 1980, PMID 7453802) reporting facilitated cellular copper uptake and Siméon et al. (Life Sci, 2000, PMID 11045606) reporting MMP-2 upregulation in fibroblast culture.

Because mass is not molar equivalence. GHK-Cu has a molecular weight of 403.9 g/mol against 1419.53 for BPC-157 and 4963.4 for thymosin beta 4, so on a per-milligram basis GHK-Cu contributes roughly 3.5 times the molar quantity of BPC-157 and 12 times that of TB-500. The 50:10:10 mass split therefore does not describe a 5:1:1 molar ratio, and any molar calculation must be done component by component from the individual molecular weights. This is the single most common arithmetic error made when working with multi-peptide blends.

Every GLOW vial is supplied from batch UKPL-262, which was assayed by Janoshik Analytical on 26/10/2026 with the content of each component (BPC-157, TB-500 and GHK-Cu) reported individually. The certificate of analysis for this batch is published on the product page and can be independently checked at /verify. UK delivery is free on orders over £69, and orders placed before 3pm UK time on a working day are dispatched the same day.

No. Once the co-lyophilised powder is dissolved, the three compounds are in one solution at a fixed ratio and cannot be separated or independently varied. That makes the blend format unsuitable for any design needing a single-compound control arm, a dose-response curve on one component, or attribution of an observed effect to a specific molecule. For those designs use the individual BPC-157, TB-500 and GHK-Cu vials, which carry their own batch numbers and their own certificates of analysis.

UK Peptide Lab sells the GLOW 70mg pre-blended vial from UK stock. Orders placed before 3pm (UK time) on a working day are dispatched the same day, and UK delivery is free over £69.

Yes. Janoshik Analytical, an independent lab, quantified each component of batch UKPL-262 on 26 October 2026: BPC-157 11.41mg, TB-500 11.05mg and GHK-Cu 58.68mg per vial. The test measures content per component and does not report a single purity figure for the blend. The full certificate is published on this page, so you can check it before ordering.

It can be bought in the UK for in-vitro laboratory research. It is not a medicine and is sold for research use only, to buyers aged 18 or over.

Buy the GLOW stack for all three at a fixed ratio from one vial and one reconstitution. Buy the individual vials to run a single-compound control, vary one concentration or attribute an effect to one molecule. Each comes with its own batch and certificate.
