Overview
In plain English
GLOW is three peptides in one vial: GHK-Cu 50mg, TB-500 10mg and BPC-157 10mg.
It is the standard blend for skin and recovery together — firmness and tone from GHK-Cu, tissue repair from the other two. People typically run it as a defined 8–12 week block rather than continuously.

How it works
What it actually does
GHK-Cu carries copper to the enzyme that cross-links collagen and elastin. Without that step you build collagen that never properly sets.
TB-500 manages the internal scaffolding repair cells use to move into damaged tissue.
BPC-157 is associated with new blood vessel growth into that tissue. Three separate jobs, no shared pathway — which is the reason for combining them.
The science in detail
GLOW places three separately characterised peptides in one vial. Their mechanisms do not intersect, and the rationale for combining them is that separation rather than any shared pathway.
GHK-Cu is the tripeptide glycyl-L-histidyl-L-lysine complexed with copper(II). Its defining chemistry is copper coordination: the N-terminal amine, the deprotonated amide nitrogen of the first peptide bond and the histidine imidazole form a square-planar chelation site with affinity comparable to serum albumin. GHK does not sequester copper inertly — it accepts Cu2+ from albumin and passes it to cellular transporters and cuproenzymes, lysyl oxidase among them, the copper-dependent enzyme that cross-links collagen and elastin into mature fibrils. Pickart and Margolina (Int J Mol Sci, 2018) additionally reported broad transcriptional modulation favouring controlled matrix turnover.
TB-500 is based on thymosin beta-4, the principal G-actin sequestering peptide in mammalian cells. It binds actin monomer in a 1:1 complex, holding it unpolymerised as a reservoir that permits rapid localised F-actin polymerisation at a migrating cell's leading edge; the activity localises to the LKKTETQ motif. Malinda et al. (Journal of Investigative Dermatology, 1999) reported accelerated dermal repair in rodent models. Its theme is intracellular — cytoskeletal remodelling and cell motility.
BPC-157 is a 15-residue fragment of a protein isolated from human gastric juice, with no identified high-affinity receptor. Hsieh et al. (Journal of Molecular Medicine, 2017) associated its pro-angiogenic activity with VEGFR2 activation and downstream Akt–eNOS signalling, attenuated by VEGFR2 blockade. Its theme is extracellular and vascular.
Matrix maturation, cell migration and perfusion are three separate constraints on tissue repair, and the blend addresses one apiece. Two caveats belong on the record. No controlled study of this three-compound combination has been published; the evidence base is preclinical work on each constituent. And co-formulating a redox-active copper complex with two copper-free peptides in one vial is not a characterised system.
Evidence
What the research shows
Collagen that matures, not just collagen
Copper delivery supports the enzyme that turns new collagen into mature, load-bearing fibre.
Repair covered from two angles
Cell movement and blood supply are handled by different constituents.
Fixed manufacture ratio
Quantities are set at manufacture; you cannot vary one constituent from a single vial.
Combination itself is untested
Each of the three has its own research base; the three-way blend does not.
Mixing & dosage
How to mix and dose it
These are the mixing and dosage instructions supplied by Purist Peptides and the manufacturer for this product.
A 3ml vial of bacteriostatic water is included free with every peptide vial you order, so you have what you need to mix this on arrival.
GLOW Stack — BPC-157 10mg + TB-500 10mg + GHK-Cu 50mg
Step 1 — mix your vial
- Draw up 3ml of bacteriostatic water into a syringe
- Wipe the rubber top of your vial with an alcohol swab and let it dry
- Insert the needle then slowly and carefully push the water down the inside wall of the vial — do not inject water straight onto the peptide powder
- Gently roll the vial between your palms until the powder dissolves completely
- Do not shake
- Allow to settle in the fridge for 5–10 minutes. The liquid should look clear
Step 2 — draw & inject your dose
Use a 1ml insulin syringe to draw and inject your dose. A 1ml syringe = 100 units.
With 3ml of water added, each 0.1ml (10 units) you draw = 2.33mg of the total blend.
| Stage | Dose | On the syringe |
|---|---|---|
| Starting | 1.17mg daily | 5 units (0.05ml) |
| Standard | 2.33mg daily | 10 units (0.1ml) |
Vial duration at standard dose: 30 days
When to inject: Once daily, morning or evening, at a consistent time. Inject subcutaneously into the abdomen or near the area of concern.
Cycle length: 8 to 12 weeks, then reassess.
How to inject
- Wipe your injection site with an alcohol swab and let it dry
- Pinch a small fold of skin on your abdomen or inject near the area of concern
- Insert the needle at a 45-degree angle into the pinched skin
- Slowly push the plunger down until empty
- Pull the needle out and apply gentle pressure with the swab
- Dispose of the needle safely in a sharps container — never recap or reuse
Storage
Keep refrigerated at 2 to 6 degrees Celsius at all times after mixing. Do not freeze. Protect from light and label the vial with the date you reconstituted it. Discard any solution that is hazy, discoloured or contains particles.

Questions
Frequently asked questions
What is in the GLOW blend?
Three peptides in one lyophilised vial: GHK-Cu, TB-500 and BPC-157, totalling 70mg of peptide content. The individual mg split between the three is not stated on the product page and should be confirmed against the batch documentation before it is quoted anywhere.
Is there published research on the blend itself?
No. No controlled study of these three compounds administered together has been published. The evidence base consists of separate preclinical work on each constituent. The combination is a formulation convention grounded in mechanistic non-overlap, not a validated protocol, and should be described that way.
Does the copper in GHK-Cu affect the other two peptides in a shared vial?
This is not characterised in the published literature. Copper(II) is redox-active, and its behaviour alongside two copper-free peptides in one solution has not been studied to our knowledge. The practical implication is conservative handling: protect from light, avoid reducing agents and chelators, and observe the solution's colour.
How does GLOW differ from KLOW?
KLOW contains the same three peptides plus KPV, the C-terminal tripeptide of alpha-MSH, at a higher total peptide content. The addition is an inflammatory-signalling component rather than a fourth repair mechanism of the same type.
How is purity verified?
Every batch is assayed by Bioindustrial Services in Boksburg, an independent biotechnology laboratory, using HPLC. We do not self-certify. The signed certificate of analysis for each batch — lab number, method and assayed result — is published on our quality standards page.
How long does delivery take?
Orders are dispatched from within South Africa with tracking. Timelines by region and courier are set out on our delivery process page.
What is the returns policy?
Unopened vials in original condition may be returned within the stated window; full terms are in our refund policy.
