Glow Blend Research Peptide Set | BPC-157, GHK-Cu and TB-500 for Canadian Researchers

Description

The Glow Blend is a three-compound research set containing BPC-157, GHK-Cu and TB-500, three peptides frequently studied side by side in cell migration and extracellular matrix research. Prometheus Labs supplies the Glow Blend as three separate lyophilized vials (BPC-157 10mg, GHK-Cu 50mg and TB-500 10mg), shipped from within Canada for laboratory research use only. This page covers what each compound is, why the set is supplied as separate vials rather than a pre-mixed blend, and how to reconstitute and store each one.

What is in the Glow Blend research set?

The Glow Blend contains three chemically distinct peptides, each in its own vial: a 15-residue synthetic peptide (BPC-157), a copper-binding tripeptide complex (GHK-Cu) and a 7-residue acetylated fragment of thymosin beta-4 (TB-500).

All three are supplied as lyophilized powder. Because the compounds differ so much in size and chemistry, the way they are packaged matters, which the next section explains.

Why is the Glow Blend supplied as three separate vials?

Supplying BPC-157, GHK-Cu and TB-500 in separate vials lets researchers treat each compound as an independent variable. Most “Glow” products on the market are a single pre-mixed vial of all three peptides. A pre-mixed vial fixes the ratio between the compounds and makes it impossible to run single-compound controls from the same material. Separate vials allow researchers to:

• Run single-compound controls. Each peptide can be tested alone, in pairs or as the full set, so any combined effect can be compared against the individual ones.
• Set the ratio. The 10:50:10 ratio in the set is a starting point, not a fixed formulation; each vial can be reconstituted at its own concentration.
• Store each compound appropriately. A reconstituted vial that is used quickly does not force the other two to be reconstituted at the same time.
• Verify identity per compound. GHK-Cu, for example, can be checked visually on its own (see below), which is not possible once mixed.

Working with three vials does mean three reconstitutions, so concentration planning is covered next.

How is each Glow Blend compound studied in laboratory research?

Each peptide in the set is studied in a different area of cell biology, which is why the three are often examined together in the same experimental models.

BPC-157

BPC-157 is a synthetic 15-amino-acid peptide based on a partial sequence of a protein identified in gastric juice. Laboratory research has examined its relationship with angiogenic signalling, including vascular endothelial growth factor (VEGF) pathways, in preclinical models (Seiwerth et al., 2018).

GHK-Cu

GHK-Cu is the copper(II) complex of the tripeptide glycyl-L-histidyl-L-lysine, first identified in human plasma. Research has focused on its copper-binding chemistry and on gene-expression data showing GHK can influence the expression of a large number of human genes in cell studies (Pickart and Margolina, 2018).

TB-500

TB-500 is a synthetic, acetylated seven-residue peptide (Ac-LKKTETQ) corresponding to the central actin-binding region of thymosin beta-4, a 43-amino-acid protein that sequesters G-actin. It is studied in actin dynamics and cell motility research (Goldstein et al., 2012). TB-500 is a fragment, not full-length thymosin beta-4.

With each compound’s research context established, the practical step is preparing stock solutions.

How do you reconstitute the three Glow Blend vials?

Reconstitute each vial separately in sterile water at a defined volume, then label each stock with its concentration in both mg/mL and mM. Because the molecular weights differ by more than three-fold, the same mg/mL gives very different molar concentrations:

Molarity is calculated from the molecular weights in the table above. At equal mg/mL, a TB-500 stock contains about 1.6 times as many molecules as a BPC-157 stock, which matters when comparing the compounds in the same assay.

GHK-Cu identity check: because GHK-Cu is a copper complex, both the powder and its solution have a distinct blue colour. A colourless GHK-Cu solution is a sign the material is not the copper complex. BPC-157 and TB-500 solutions should be clear and colourless.

Once reconstituted, the three stocks have different handling needs.

How should the Glow Blend vials be stored?

Store all three vials lyophilized, sealed and frozen until use; once reconstituted, refrigerate each stock and use it within its own working window. Keeping the vials separate means only the compound being used needs to be reconstituted. Allow each vial to reach room temperature before opening to limit moisture uptake, and avoid repeated freeze-thaw cycles by freezing single-use aliquots. For full handling guidance, see the peptide reconstitution and storage guide and lyophilization science.

Glow Blend research FAQ

Is the Glow Blend a single pre-mixed vial?

No. The Glow Blend is supplied as three separate vials: BPC-157 10mg, GHK-Cu 50mg and TB-500 10mg. This allows each compound to be reconstituted and tested independently.

What is the difference between TB-500 and thymosin beta-4?

Thymosin beta-4 is a 43-amino-acid protein. TB-500 is a synthetic seven-residue fragment (Ac-LKKTETQ) corresponding to its actin-binding region, with a molecular weight of 889.01 g/mol.

Why is the GHK-Cu solution blue?

GHK-Cu is a complex of the GHK tripeptide with copper(II), which gives the powder and its solution a blue colour.

Is the Glow Blend shipped from within Canada?

Yes. Every Glow Blend set is fulfilled domestically by Performance Peptides Canada, with no cross-border customs clearance.

Is the Glow Blend intended for human or animal use?

No. All three compounds are sold strictly for in vitro laboratory research. They are not drugs, natural health products, cosmetics or supplements, and are not for human or animal consumption.

The individual compounds are also available on their own: BPC-157, GHK-Cu and TB-500.

Key takeaways

• The Glow Blend is three separate Prometheus Labs vials: BPC-157 10mg, GHK-Cu 50mg and TB-500 10mg.
• Separate vials allow single-compound controls and researcher-defined ratios, unlike pre-mixed “Glow” vials.
• The three compounds differ more than three-fold in molecular weight, so equal mg/mL stocks have very different molarities.
• GHK-Cu solutions are blue; a colourless solution indicates the copper complex is absent.
• TB-500 is the Ac-LKKTETQ fragment of thymosin beta-4, not the full-length protein.
• Shipped within Canada, for laboratory research use only.
