Peptide stack guide
The GLOW Stack: GHK-Cu, BPC-157 & TB-500 explained
GLOW is the most searched skin-research peptide blend — three compounds with complementary research profiles, combined in a single pre-mixed pen. This guide covers the exact composition, how GLOW differs from KLOW, and what published research says about each component.
Three-compound blend
GHK-Cu, BPC-157 and TB-500 at research-standard ratios in one pre-mixed pen — no separate vials, no manual mixing.
Third-party tested
Independent laboratory verification of identity and purity on every batch, with certificates of analysis available.
Cold-chain shipped
Temperature-controlled packaging and tracked delivery across the UK, EU and UAE.
What's in the GLOW stack?
The GLOW blend brings together three peptides that dominate the skin-repair and tissue-research literature:
| Compound | Class | Primary research focus |
|---|---|---|
| GHK-Cu | Copper tripeptide | Collagen and elastin synthesis, skin-remodelling and anti-ageing research models |
| BPC-157 | Synthetic pentadecapeptide | Tissue repair, tendon and gut-lining research models |
| TB-500 | Thymosin beta-4 fragment | Cell migration, angiogenesis and recovery research |
Why researchers combine these three compounds
Each compound in GLOW is studied for a different mechanism: GHK-Cu in copper-dependent enzyme activity and collagen synthesis, BPC-157 in cytoprotection and repair signalling, and TB-500 in actin regulation and cell migration. Blended formulations exist because research protocols frequently examine these pathways together — particularly in skin-aging, wound-model and tissue-repair study designs. Our peptide synergy research article covers the published literature on multi-peptide study designs.
