KLOW is a quad-peptide research blend — GHK-Cu, BPC-157, TB-500 and KPV — co-lyophilized in a single 80 mg vial at 50 mg, 10 mg, 10 mg and 10 mg respectively.
The four components are structurally unrelated and are normally studied separately. GHK-Cu is a copper-binding tripeptide; BPC-157 is a 15-amino-acid sequence derived from a protein found in gastric juice; TB-500 is a thymosin β4 peptide (CAS 77591-33-4), associated with actin binding; KPV is a tripeptide corresponding to the C-terminal fragment of α-MSH. They are supplied as a blend rather than as a single molecule.
Co-lyophilisation matters practically: all four peptides reconstitute from one vial in one step, so the ratio between them is fixed at manufacture rather than by pipetting four separate stocks. Nothing on this page should be read as a claim that the combination produces any particular result.
Blend components
GHK-Cu
A copper-binding tripeptide (glycyl-L-histidyl-L-lysine complexed with copper(II)). CAS 89030-95-5. Supplied here at 50 mg per vial, HPLC-verified to ≥99%. It is the largest component of the blend by mass.
BPC-157
A 15-amino-acid peptide (a pentadecapeptide) derived from a sequence identified in gastric juice. CAS 137525-51-0. Supplied here at 10 mg per vial, HPLC-verified to ≥99%.
TB-500
A thymosin β4 peptide, CAS 77591-33-4, associated with actin binding. Supplied here at 10 mg per vial, HPLC-verified to ≥99%.
KPV
A tripeptide (Lys-Pro-Val) corresponding to the C-terminal fragment of α-melanocyte-stimulating hormone. CAS 67727-97-3. Supplied here at 10 mg per vial, HPLC-verified to ≥99%.
KLOW: published literature
The references below concern the individual components, not this blend. All four peptides have been studied principally in laboratory and animal models; none is an approved drug, and the GHK-Cu + BPC-157 + TB-500 + KPV combination has not been evaluated as a combination in published clinical trials. They are cited as literature — APEX 100 Research makes no claim about outcomes, efficacy or suitability for any purpose.

Common questions
What is in the KLOW blend?
One 80 mg vial containing GHK-Cu (50 mg), BPC-157 (10 mg), TB-500 (10 mg) and KPV (10 mg),
co-lyophilized together. Catalogue SKU A100-KBT80.
What does ≥99% HPLC purity mean?
High-performance liquid chromatography separates the sample into its components and measures each as a proportion of the total. ≥99% means the target peptide accounts for at least 99% of the material by that method. The chromatogram showing this is included in the lot’s COA.
Can I see the COA before ordering?
Yes. Sample documentation is on our COA page, and we will send the specific COA for any lot on request — before or after purchase.
Is this a drug product?
No. This material is supplied strictly as a research material. It is not a drug product and is not for human consumption.
How is this shipped?
Sourced and shipped within the United States, typically 2-day delivery. Lyophilized peptides are stable in transit; refrigerate on arrival.
Why are both peptides in one vial?
They are co-lyophilized, so the 10 mg : 10 mg ratio is fixed at manufacture and both reconstitute in a single step. It removes the pipetting error involved in combining two separate stocks.
KLOW Purity & COA
Every lot is tested before release and ships with its own certificate of analysis. We publish the COA unredacted — including the lot number, the test date and the actual chromatogram — rather than a summary figure.
HPLC purity
High-performance liquid chromatography establishes purity against the ≥99% specification. The chromatogram is included in the COA, not just the resulting number.
Mass spectrometry
Identity is confirmed by mass spectrometry against the expected molecular weight of each component (GHK-Cu 340.384 g/mol, BPC-157 1419.556 g/mol, TB-500 4963 g/mol).
Lot traceability
Each vial’s lot number corresponds to a specific COA on file. Request the document for any lot you have received at any time.

Handling and storage
Supplied lyophilized. Standard laboratory handling for peptides of this class applies.
| Lyophilized storage | 36–46 °F short term; −4 °F for extended storage, protected from light |
|---|---|
| Reconstitution | Bacteriostatic water is the common choice for laboratory reconstitution. Add solvent slowly against the vial wall; do not inject directly onto the powder. |
| Mixing | Swirl gently until dissolved. Do not shake or vortex — mechanical agitation can shear peptide chains. |
| After reconstitution | Refrigerate at 36–46 °F. Avoid repeated freeze-thaw cycles. |
| Light | Protect from light at all stages. |
