What Is the KLOW Stack?
The KLOW Stack is a research blend that brings four separate research peptides together into one lyophilised vial. Instead of reconstituting and storing four individual compounds, a researcher working with all four prepares a single vial. North Peptides UK supplies it as an 80mg vial, listed with supplier-stated 99%+ purity.

The Four Compounds
The blend contains the following research compounds, each also stocked individually:
- GHK-Cu — a copper peptide research compound. Its solutions carry a characteristic faint blue-green tint from the copper.
- TB-500 — a Thymosin Beta-4 fragment research compound, studied in tissue-repair research models.
- BPC-157 — a synthetic 15-amino-acid peptide and a frequent subject of tissue-repair and gastrointestinal research.
- KPV — a short tripeptide research compound studied in inflammation-related research models.
| Component | Type | Also sold as |
|---|---|---|
| GHK-Cu | Copper peptide | 50mg vial |
| TB-500 | Thymosin Beta-4 fragment | 10mg vial |
| BPC-157 | Synthetic peptide | 10mg vial |
| KPV | Tripeptide | 10mg vial |
Why Combine Them?
The four compounds are combined for practical convenience in research workflows that involve all of them. A single blended vial means one reconstitution, one storage vial, and one preparation date to track, rather than four. For a research programme that works across these compounds together, that is a simpler handling setup.
Researchers who only need one of the four can buy that compound on its own — each is stocked individually.
Handling and Reconstitution
The KLOW Stack reconstitutes the same way as any single peptide. All four compounds are water soluble, so they dissolve together in bacteriostatic water; around 2ml per vial is a common starting volume. Add the solvent down the side of the vial, swirl gently, and refrigerate the prepared solution. Our reconstitution guide covers the full procedure.
