— About this compound
KLOW Blend.
Class · Merit co-formulation: BPC-157 + GHK-Cu + TB-500 + KPV
Origin. KLOW is a Merit-specific four-component co-formulation. It extends the GLOW blend with KPV, the C-terminal tripeptide (lysine-proline-valine) of alpha-melanocyte-stimulating hormone (α-MSH).
KLOW combines four peptides recurrent in repair and immune-signaling research: BPC-157, GHK-Cu, TB-500, and KPV. KPV is the C-terminal fragment of α-MSH and is studied for anti-inflammatory signaling that appears, in some models, to act independently of the melanocortin-1 receptor.
As a co-formulation, KLOW has no separate published record; the literature belongs to each component. Merit supplies it as a single research preparation for laboratory use only.
— Common research applications
- Tissue-repair and remodeling research (component-based)
- Inflammation-pathway models (KPV)
- Extracellular-matrix studies
- Comparative peptide co-formulation research
— Mechanism
How it's been studied.
Component-level: BPC-157 (cytoprotection / angiogenesis), GHK-Cu (matrix remodeling), TB-500 (actin / cell migration), and KPV (NF-κB-pathway modulation in inflammation models). No combined mechanism is established for the blend.
Mechanism descriptions reflect findings reported in the preclinical and basic-research literature. They are not clinical conclusions and not statements of therapeutic effect.

— Why Merit
The supplier difference.
How Merit compares to the two alternatives most research buyers consider for KLOW Blend.
Comparison reflects published facility status and standard industry practice. Compounding pharmacy availability of research peptides varies by jurisdiction.

— Common Questions
Got questions.
What is KLOW Blend?+
KLOW combines four peptides recurrent in repair and immune-signaling research: BPC-157, GHK-Cu, TB-500, and KPV. KPV is the C-terminal fragment of α-MSH and is studied for anti-inflammatory signaling that appears, in some models, to act independently of the melanocortin-1 receptor.
How does KLOW Blend work?+
Component-level: BPC-157 (cytoprotection / angiogenesis), GHK-Cu (matrix remodeling), TB-500 (actin / cell migration), and KPV (NF-κB-pathway modulation in inflammation models). No combined mechanism is established for the blend.
What class of compound is KLOW Blend?+
KLOW Blend is classified as merit co-formulation: BPC-157 + GHK-Cu + TB-500 + KPV.
What is the reported half-life of KLOW Blend?+
Component-dependent (see the individual component records).
Why does Merit ship lyophilized?+
Lyophilized format gives ≥24 months sealed stability at -20°C — significantly longer than pre-reconstituted, which has a 30-day shelf life once in solution. You reconstitute at the moment of use, when potency is at its peak.
How do I verify my lot's COA?+
Your vial label carries the lot number. Use that number to pull the COA on our site at any time — the COA for your specific batch lives at /coa/[lot-id] and stays accessible for the life of the product.
What does "pharmacy-verified" actually mean?+
A US-licensed pharmacist on our team reviews every batch before release. They sign off on the lot's purity, identity, and release. No batch ships without that sign-off — and that's what separates Merit from a reseller catalog.
Will my bank flag this purchase?+
Statements show as Merit Sciences LLC. Standard merchant descriptor — does not trigger category-code flags. All major cards and PayPal accepted at checkout.
How fast does it ship?+
48 hours from order to dispatch, Monday through Thursday. UPS Ground, tracked + insured. From Dallas, TX, most US addresses receive within 3-5 business days.
