UK peptide blends explained: what is actually in "Wolverine", "Glow" and "KLOW"
By Jamie, Editor · The Peptide Watch · updated 11 July 2026
Sellers often list research peptides under blend nicknames rather than their components. Here is what the common blends contain, and why a certificate of analysis for a blend has to identify each compound, not just the mixture.
| Blend name | Components | Notes |
|---|---|---|
| Wolverine | BPC-157 + TB-500 | The most common repair blend: two tissue-repair research peptides in one vial. |
| Glow | GHK-Cu + BPC-157 + TB-500 | A copper-peptide plus the two repair peptides. |
| KLOW | GHK-Cu + BPC-157 + TB-500 + KPV | Glow plus KPV, an anti-inflammatory fragment. |
| CJC-1295 + Ipamorelin | CJC-1295 + Ipamorelin | A growth-hormone-secretagogue pairing, often sold pre-mixed. |
| KPV / Copper blends | varies | Marketing names vary between sellers; always read the component list, not the nickname. |
Why blends make verification harder
A blend is several peptides in one vial, so a single purity figure tells you nothing about the ratio or the identity of each component. A genuine certificate should report each compound separately; if it shows one number for the mixture, or names a lab you cannot check, you cannot verify what you have. See how to verify a Janoshik COA, or check the single-compound pages for BPC-157, TB-500 and GHK-Cu.
