What is in this blend
- 50 mg GHK-Cu + 10 mg BPC-157 + 10 mg TB-500 or TB4 + 10 mg KPV
Compositions vary by vendor. The price table compares whole-vial totals, not the amount of any one component.
Why people stack them
KLOW extends the GLOW ingredient set by adding KPV. Vendors therefore position it around overlapping skin, tissue, and inflammation research themes represented by the four separate component literatures.
That ingredient overlap is not clinical proof for the mixture. Research on KLOW as a fixed four-component combination is not established, so each component guide is the better place to assess evidence.
What to check before you buy
- Confirm every named ingredient. PeptidePub matches blends by composition, not by the marketing name on the vial.
- Look for a lot-specific COA that identifies and measures each component.
- Separate the whole-vial total from the milligrams assigned to each component.
- Remember that price per mg in the table is calculated from the whole vial.
Handling and storage
Because the vial contains GHK-Cu, use the stricter light-protection guidance in the GHK-Cu guide. Review the BPC-157, TB-500, and KPV guides as well, then follow the vendor's lot documentation.
No published stability standard was found for the four-component mixture itself.

GO DEEPER
This guide covers one compound. We wrote the book on all 45.
The Peptide Handbook takes everything we know from testing vendors for a living and turns it into five readable books: what each compound actually does, what the evidence really says, and the honest call when the answer is "skip this one." Plus the dosing tables, calendars, and trackers that make it usable.
