What is GLOW?
GLOW is one pre-blended vial holding BPC-157 10mg, TB-500 10mg and GHK-Cu 50mg: 70mg of lyophilised powder in total. One reconstitution puts all three into solution. The powder is blue, from the copper in GHK-Cu.
Full description
BPC-157 is the 15-residue pentadecapeptide GEPPPGKPADDAGLV (1419.53 g/mol, CAS 137525-51-0). TB-500 is synthetic thymosin beta 4, 43 residues (4963.4 g/mol, CAS 77591-33-4). GHK-Cu is the copper(II) complex of glycyl-L-histidyl-L-lysine (403.9 g/mol, CAS 89030-95-5).
The blend itself has not been studied as a combination. Each finding cited here comes from work on one component alone.
GLOW Research Applications
- BPC-157: Hsieh and colleagues (J Mol Med, 2017) linked its angiogenic effect in chick membrane and endothelial tube assays to VEGFR2 activation and up-regulation.
- BPC-157: in cultured rat tendon fibroblasts it increased migration and FAK and paxillin phosphorylation (Chang et al., J Appl Physiol, 2011).
- TB-500: the seven amino acid actin-binding motif of thymosin beta 4 matched the whole molecule in endothelial migration assays at about 50 nM (Philp et al., FASEB J, 2003).
- GHK-Cu: raised MMP-2, TIMP-1 and TIMP-2 in dermal fibroblast culture. Copper ions alone reproduced the MMP-2 effect, GHK alone did not (Siméon et al., Life Sci, 2000).
Study details
Bock-Marquette and colleagues (Nature, 2004) found thymosin beta 4 forms a complex with PINCH and integrin-linked kinase, activating Akt in cardiac cells. Pickart and colleagues (Nature, 1980) showed GHK readily binds copper(II) and increases copper uptake into cultured hepatoma cells. These findings come from different systems and cannot be added up into a prediction for the blend.
GLOW vs KLOW vs Individual Vials
KLOW holds the same three components at the same masses plus KPV 10mg, 80mg in total. KPV adds a gut epithelial and PepT1 uptake literature. Individual BPC-157, TB-500 and GHK-Cu vials are the only format that allows a single-compound control, independent concentrations or attribution of an effect to one molecule. Some suppliers sell GLOW as a kit of five or six separate vials; ours is one pre-blended vial.
Research Overview
Chang and colleagues (J Appl Physiol, 2011) grew tendon fibroblasts from rat Achilles tendon with BPC-157. It sped up outgrowth from tendon explants and raised survival under hydrogen peroxide stress, while cell proliferation was unchanged. Philp and colleagues (FASEB J, 2003) found that peptides lacking any part of the thymosin beta 4 actin motif were inactive, and that soluble actin blocked adhesion and sprouting.
Pickart and colleagues (1980) first isolated GHK with roughly equimolar copper, and saw maximal effects on hepatoma cells when copper and iron were added with the peptide. Siméon and colleagues (2000) described GHK-Cu as an activator of both connective tissue production and extracellular matrix remodelling.

Storage and Reconstitution
Store GLOW powder at -20°C, away from light and moisture, for up to 24 months. After reconstitution, keep the solution at 2-8°C in a light-protected container and use it within 4 weeks. For longer storage, freeze single-use aliquots at -20°C and avoid repeated freeze-thaw cycles.
Vials are sold on their own, without bacteriostatic water for mixing or other supplies.
How to reconstitute and handle
Let the vial and the bacteriostatic water reach room temperature and swab both stoppers with alcohol. Add the water slowly down the inside wall of the vial and swirl gently until dissolved. Do not shake or vortex. Expect a blue to blue-violet solution from the Cu(II) in GHK-Cu. A colourless or green-tinged solution suggests the copper complex has broken down. Use glass or good-quality polypropylene labware and avoid long contact with stainless steel.
- Strong chelators, phosphate-rich buffers and reducing agents in a medium compete for the copper and change the species present.
- Work away from direct light and use amber or foil-wrapped tubes for aliquots.
For the full method, see the peptide reconstitution guide and the reconstitution calculator.

Frequently Asked Questions
What is in a GLOW 70mg vial?
70mg of blue lyophilised powder: BPC-157 10mg, TB-500 10mg and GHK-Cu 50mg, co-lyophilised in one vial.
Is GLOW supplied as one pre-blended vial or as a multi-vial kit?
One pre-blended vial, so there is one reconstitution and one container to store and label. Some suppliers sell GLOW as a kit of five or six separate vials that you reconstitute one by one.
Has the GLOW peptide blend been studied as a combination?
No published study has tested BPC-157, TB-500 and GHK-Cu together, at this ratio or any other, and no combined effect has been shown. Treat the blend as three compounds in one container and design controls to match.
What is each component of the GLOW stack studied for?
BPC-157 for angiogenic signalling and fibroblast migration, TB-500 (thymosin beta 4) for actin binding and cell movement, and GHK-Cu for copper transport and extracellular matrix remodelling. The cited studies each examined one component alone.
Why does GHK-Cu make up 50mg of the 70mg GLOW blend?
The mass split is 50:10:10, but the molar split is very different. At 403.9 g/mol, 50mg of GHK-Cu is about 124 µmol, against about 7.0 µmol for 10mg of BPC-157 at 1419.53 g/mol. Do molar calculations component by component.
Can the components of a GLOW blend vial be separated after reconstitution?
No. Once dissolved, the three compounds share one solution at a fixed ratio. For a single-compound control or a concentration series on one component, use the individual BPC-157, TB-500 and GHK-Cu vials.
Where can I buy GLOW peptide in the UK?
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.
What purity is your GLOW 70mg blend, and is it third-party tested?
Yes. Marfleet Analytical Services, an independent lab, confirmed by RP-HPLC that each component of batch UKPL-262, GHK-Cu, BPC-157 and TB-500, matches its reference standard. The full certificate is published on this page, so you can check it before ordering.
Is GLOW peptide legal to buy in the UK for research?
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.
Should I buy the GLOW stack or the individual peptides separately?
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.
