— About this compound
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.
— Mechanism
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.
— How it’s made
Every Nexa batch follows the same documented path. Five steps, every one verifiable.
01
Sourcing
Active pharmaceutical ingredient sourced from FDA-registered manufacturers. Identity confirmed against reference standard before any compounding begins.
02
Compounding
Lyophilized in a cleanroom at our US facility. The powder format gives ≥24 months sealed stability — no cold-chain shipping required.
03
Verification
Reverse-phase HPLC-UV (UV/MS for higher-MW peptides) confirms identity and purity for every batch before it leaves the lab. The chromatogram is archived.
04
Release
No batch ships until an independent laboratory has returned its identity and purity results and the certificate is published in the COA library.
05
Dispatch
Sealed vials with a QR code on the label that opens the COA library. Order before 2pm CT Monday–Thursday for same-day dispatch. UPS Ground, tracked + insured.
