What is the GLOW Pen?
A breakdown of the GLOW Pen's three-component formulation, how it compares to KLOW and WOLVERINE, and what the certificate of analysis actually records.
Key takeaways
- •GLOW combines three separately studied compounds in one cartridge: GHK-Cu, BPC-157 and TB-500.
- •The total mass per cartridge is 105mg, dispensing 0.350mg per 0.01ml click across 300 clicks.
- •GLOW, KLOW and WOLVERINE share overlapping components but differ in exactly which compounds, and how much of each, are included.
- •A certificate of analysis records chemical quality for a batch as tested, not a claim about combined effects. The GLOW certificate is being re-issued and is not yet published.
- •GLOW is a market name, not a regulated or standardised term, and Celyfe states the exact per-component mass rather than relying on the name alone.
What is in the cartridge
The GLOW Pen contains a single 3ml cartridge formulated with three compounds: GHK-Cu (a copper tripeptide) at 75mg, BPC-157 (a pentadecapeptide) at 15mg, and TB-500 (a synthetic fragment related to thymosin beta-4) at 15mg, for a combined total of 105mg per cartridge. Each 0.01ml click of the pen dispenses 0.350mg of this combined formulation, and one cartridge provides 300 clicks.
Each of these three compounds is also studied individually in the published literature, and each has its own dedicated guide on this site covering its structure and the research areas it appears in: see our guides to GHK-Cu, BPC-157 and TB-500 for detail on each component.
Why these three compounds are combined
GHK-Cu, BPC-157 and TB-500 come from different research literatures (extracellular matrix and gene-expression studies for GHK-Cu, gastric-derived peptide research for BPC-157, and actin-binding and cell-migration research for TB-500), and combining them into a single cartridge is a formulation and market decision rather than a claim that the literature has established a combined effect. Suppliers group compounds like this for the convenience of researchers who want to study more than one compound without managing several separate vials, not because the combination itself has been the subject of dedicated published trials.
GLOW compared with KLOW and WOLVERINE
These three Celyfe pens share overlapping components at different combinations and total masses, which is worth checking carefully rather than assuming from the name alone.
| Pen | Components | Total mass | Per click |
|---|---|---|---|
| GLOW | GHK-Cu 75mg, BPC-157 15mg, TB-500 15mg | 105mg | 0.350mg |
| KLOW | GLOW formulation plus KPV 15mg | 120mg | 0.400mg |
| WOLVERINE | BPC-157 15mg, TB-500 15mg | 30mg | 0.100mg |
What the certificate of analysis records
The GLOW certificate is being re-issued and is not yet published, so no GLOW purity or content result is claimed here. When it is published in the COA library, it should report results for each of the three components separately. A certificate of analysis is a chemical quality record for the formulation as manufactured; it does not represent, and should not be read as, a statement about any combined biological effect of the three components together.
A market name, not a regulated term
GLOW, like KLOW and WOLVERINE, is a naming convention used across the research peptide market rather than a standardised or regulated term, and different suppliers may use similar names for different formulations. This is why Celyfe states the labelled mass of each individual component on every listing, so researchers can verify precisely what a cartridge contains rather than relying on the product name alone.
Research use only
The GLOW Pen is supplied for laboratory and research use only. Nothing in this guide describes or implies administration to a human or animal body, and none of the components are licensed medicines or supplements.
