Why buy KLOW Peptide Blend from TrueBond Labs
Four peptides, one certificate
An independent third-party lab tested our published KLOW lot. The certificate names all four peptides, reports identity as confirmed for the vial and reports HPLC purity of at least 99%. Read the KLOW certificate and check it against the lot code on your vial.
80mg, sold by total
KLOW comes in one size: 80mg of combined freeze-dried powder in a sealed 3 mL vial. It's labeled and sold by that total, without an amount listed per component. The certificate is where you'll see GHK-Cu, BPC-157, TB-500 and KPV named one by one. BPC-157 is also sold alone as a 10mg vial.
GLOW plus KPV
KLOW is the three peptides in our GLOW blend with KPV added. GHK-Cu is also sold alone as a 100mg vial. If KPV is all you need, there's a standalone KPV vial. All of our multi-peptide vials, including the Wolverine blend, are on the peptide blends page.
What is KLOW Peptide?
KLOW is a four-peptide blend of GHK-Cu, BPC-157, TB-500 and KPV, freeze-dried together in one fill. Each of the four is a different molecule. GHK-Cu is a copper-binding tripeptide (glycyl-histidyl-lysine) first isolated from plasma. BPC-157 is a synthetic 15-amino-acid peptide taken from a sequence in a gastric protein.
TB-500 is a synthetic peptide related to thymosin beta-4, an actin-binding protein, and the certificate lists it as thymosin beta 4. KPV is the tripeptide lysine-proline-valine, the last three amino acids of alpha-MSH, and it appears in published research on melanocortin receptor biology. With all four in one vial, there's one lot code to record and one document to read.

KLOW Peptide Blend: frequently asked questions
What is KLOW peptide?
KLOW is a four-peptide blend of GHK-Cu, BPC-157, TB-500 and KPV. Ours is a single 80mg vial of freeze-dried powder, made in the USA. It's sold for laboratory research only, not for human or animal use, to buyers 21 and over.
How much of each peptide is in KLOW?
KLOW is labeled and sold as 80mg of combined peptide, and we don't list a separate amount for each component. The certificate for our published lot names all four individually.
How is KLOW different from GLOW?
The GLOW blend has three peptides: BPC-157, GHK-Cu and TB-500. KLOW has those three plus KPV, for 80mg in total. They're separate products with separate lot codes and certificates, tested the same way. Our KLOW vs GLOW page compares the two vials row by row.
How do I check the certificate for my KLOW vial?
Find the lot code on your vial label and look it up on our lab reports page, where certificates are filed by lot code. You can browse the published certificates before you order, then check your vial's code once it arrives. If it isn't listed yet, email support@
How should I store KLOW?
Freeze it. A sealed KLOW vial kept at −20°C (−4°F) holds for 24 months or more as lyophilized powder. Keep it in the dark, and don't let it thaw and refreeze over and over.
