Structural Composition
GHK-Cu (copper tripeptide complex) + BPC-157 (15-amino-acid synthetic peptide) + TB-500 (Thymosin Beta-4 analog peptide) + KPV (Lys-Pro-Val tripeptide)
Physical Properties
KLOW is a composite peptide blend combining GHK-Cu (a copper (II) coordination complex of Gly-His-Lys), BPC-157 (a 15-amino-acid synthetic peptide), TB-500 (a 43-amino-acid Thymosin Beta-4 analog), and KPV (a short Lys-Pro-Val tripeptide). Because the formulation contains multiple distinct peptide structures and a metal-bound peptide complex, overall molecular formula and molecular weight are inherently variable and depend on blend ratios and hydration state. Lyophilized presentation supports storage stability, while protection from moisture, light, and repeated freeze–thaw cycles helps maintain structural integrity and analytical consistency for laboratory and research applications.
Analysis & Documentation

Analytical Methods
Testing is carried out per lot by an independent laboratory. The methods measure what the material is and how much of it is the target compound:
- RP-HPLC — reverse-phase separation of the target from process-related impurities; purity is reported as area percent of the main peak
- Mass spectrometry — observed mass compared against the expected molecular mass above
- Retention time — compared against a reference standard run under the same conditions
- Chromatogram — reproduced on the certificate so the peak and any shoulders can be inspected directly
Material & Documentation
What arrives, and how to tie it back to its paperwork:
- Appearance as supplied — Blue-tinted to off-white lyophilized powder (blend-dependent)
- Solubility — Water, phosphate-buffered saline (PBS)
- Lot number — printed on the container label and used to look up the certificate
- Certificate — indexed by lot at Certificates of Analysis
Laboratory Handling and Storage Protocols
Lyophilized Powder Storage
- Store at –20°C to –80°C in the original, sealed vial
- Protect from light exposure and moisture
- A desiccated storage environment is recommended
- Stability data suggests extended stability when stored at −20 °C or below.
Reconstituted Solution Storage
- Short-term storage: Up to 7 days at 4°C
- Long-term storage: Store at –20°C in aliquots
- Use single-use aliquots to preserve peptide integrity
- Minimize freeze–thaw cycles; single-use aliquots are strongly recommended
Stability Characteristics
KLOW is a multi-component peptide research blend containing GHK-Cu, BPC-157, TB-500, and KPV. As a composite formulation, overall stability depends on proper cold storage, protection from light, and minimized mechanical agitation during preparation. When handled according to standard peptide laboratory protocols, the blend maintains structural integrity and solubility suitable for in vitro and analytical research applications.
Frequently Asked Questions
What is KLOW?
KLOW is a research peptide blend combining:
-
GHK-Cu (copper-binding tripeptide complex)
-
BPC-157 (synthetic gastric peptide fragment)
-
TB-500 (Thymosin Beta-4 fragment)
-
KPV (Lys-Pro-Val tripeptide fragment)
It is formulated for laboratory investigation of combined peptide pathway interactions.
Why combine these peptides in a single blend?
Blended peptide formulations allow researchers to evaluate:
-
Potential synergistic pathway interactions
-
Complementary signaling mechanisms
-
Comparative effects versus individual peptide controls
This approach may reduce experimental complexity compared to running separate preparations in certain models.
Is KLOW a single peptide?
No. KLOW is a formulated multi-peptide blend, not a single amino acid sequence. Each component retains its own structural and signaling characteristics within the formulation.
How is KLOW supplied?
KLOW is typically supplied as a lyophilized (freeze-dried) powder blend in sealed research vials to maintain stability during storage and shipment.
How should unreconstituted KLOW be stored?
Lyophilized KLOW should be stored:
-
Long-term: −20 °C to −80 °C
-
Short-term: 2–8 °C
Keep vials sealed and protected from light and moisture until use.
How should reconstituted KLOW be handled and stored?
Once reconstituted:
-
Store at 2–8 °C for short-term laboratory use
-
For extended storage, aliquot and freeze at −20 °C or below
-
Minimize freeze–thaw cycles using single-use aliquots
-
Protect from prolonged light exposure (especially due to GHK-Cu)
-
Gently swirl to mix; avoid vigorous agitation
Does KLOW require a Certificate of Analysis (COA)?
Yes. A Certificate of Analysis (COA) should be available for each batch, verifying the identity and purity of each peptide component within the blend to ensure research quality and traceability.
Is KLOW FDA-approved?
No. KLOW is not FDA-approved as a drug, supplement, or therapeutic product. It is sold exclusively as a research compound blend and must not be marketed or used for diagnostic, therapeutic, or consumption purposes.
