Compound reference
KLOW, GLOW and Wolverine peptide blends: what is in each vial and what a certificate must show
By Vitality Chems · Published · updated · vendor-authored explanatory note
Short answer
These are trade nicknames, not compound names. In our catalog "Wolverine" is a label used on some lots of our BPC-157 / TB-500 10 mg / 10 mg blend. "GLOW" adds GHK-Cu to those two (our listing is labeled 10/10/50 mg). "KLOW" adds KPV as a fourth component (our listing is 80 mg total). Because the name says nothing about amounts, a buyer should rely on the label's per-component figures and a certificate that reports a quantity and identity for every component, not one purity number for the vial.
Catalog materials discussed on this page
| Blend name | Components | Listing label | Component identities |
|---|---|---|---|
| Wolverine (BPC/TB blend) | BPC-157, TB-500 | 10 mg / 10 mg | BPC-157 C62H98N16O22, 1419.5 g/mol; TB-500 Ac-LKKTETQ C38H68N10O14, 889.0 g/mol |
| GLOW | BPC-157, TB-500, GHK-Cu | 10/10/50 mg | adds GHK-Cu (copper complex of Gly-His-Lys) |
| KLOW | GHK-Cu, BPC-157, TB-500, KPV | 80 mg total | adds KPV (Lys-Pro-Val, PubChem CID 125672, C16H30N4O4, 342.4 g/mol) |
Why blend names need care
A nickname tells you which peptides a seller put in the vial, not how much of each. Two sellers can use the same name for different ratios. Read the per-component amounts on the label, and if the label gives only a total (as with an 80 mg KLOW vial), ask the seller for the split and for the lot report that measured it.
None of these blends is an approved drug. They are laboratory research materials only, not for human or animal use, and nothing here describes effects or uses.
What the certificate should report
Each extra component multiplies the work. A four-component vial needs four labeled HPLC peaks, four measured quantities and identity for each peptide. GHK-Cu adds a copper-complex question: whether the report measured the peptide, the complex, or both.
For the two-component blend we publish one report: Vanguard Laboratory, reported 2026-02-26, HPLC-UV/VIS, quantities BPC-157 11.26 mg · TB-500 12.10 mg, sample identified as "Orange Cap" rather than a lot number, with no mass-spectrometry identity. We have no published report yet for our GLOW or KLOW listings; ask for the exact-lot report before relying on either.
- One labeled, resolved peak per component.
- A measured mg value for each component, not just a total.
- Mass-spectrometry identity for each component, or a plain statement that it was not run.
- Lot on the report matches the vial; the lab confirms the report.

Frequently asked
What is in a KLOW peptide blend?
KLOW is a market name for a four-peptide research blend of GHK-Cu, BPC-157, TB-500 and KPV. Our listing is 80 mg total; ask for the per-component split and the lot report.
What is the difference between GLOW and KLOW?
GLOW combines BPC-157, TB-500 and GHK-Cu. KLOW adds KPV as a fourth component.
What is the Wolverine blend?
A market name for a BPC-157 / TB-500 two-peptide vial. In our catalog it appears on some lots of the BPC-157 / TB-500 10 mg / 10 mg blend.
Are these blends drugs?
No. They are research materials only, not drugs, and not for human or animal use.
