02Verify your vial
Every vial label carries a QR code. Point your phone camera at it.
The code opens that lot's certificate with every assay value. No phone? Type the lot from your packing slip on Verify a lot.
Each signed certificate links to the lab's own verification page, so the report can be confirmed independently of us.

Components
Each component is confirmed separately on the lot certificate.
GHK-Cu50 mg · 3 residues
KPV20 mg · 3 residues
Each component is built from its own sequence with ideal bond lengths and angles, so every connection is exact. They are separate molecules in the vial, not bonded to each other; the stack is for viewing only. Poses are idealised, not measured conformations. Each component is confirmed separately on the lot certificate.
Structure viewer04In the lab
GHK-Cu and KPV are each studied on their own pathways in laboratory research. This blend combines them in one vial; the map shows the best-characterized pathway reported for each.
Blend
GHK-Cu / KPVBlend of GHK-Cu and KPVMatrix remodeling
Endpoint studied
More MMP-2, its mRNA, TIMP-1 and TIMP-2; copper ions alone matched the MMP-2 rise, GHK alone did not.
Simeon 2000 · PMID 11045606Gut cell signaling
Endpoint studied
Taken up through PepT1; nanomolar KPV lowered NF-kB and MAP kinase activation and cytokine secretion.

05Research history
5 milestones, each linked to its PubMed record
GHK-Cu · Experientia
The growth-modulating tripeptide found in serum is identified as glycyl-histidyl-lysine.
PubMed · PMID 858356GHK-Cu · The Biochemical Journal
The tripeptide binds copper(II) strongly enough to compete with albumin, holding about 42% of it at equal concentrations.
PubMed · PMID 7340824KPV · Peptides
Lys-Pro-Val, alpha-MSH residues 11 to 13, lowers fever in a pyrogen model, though less potently than the full hormone.
PubMed · PMID 6333677GHK-Cu · FEBS Letters
GHK-Cu raises collagen synthesis by fibroblasts in culture from picomolar levels, without changing cell number.
PubMed · PMID 3169264KPV · FASEB Journal
The C-terminal tripeptide alpha-MSH [11-13] reduces swelling in a contact inflammation model.

About GHK-Cu / KPV, its certificate and your order.
Email [email protected], Monday to Friday. A person replies within one business day.
The current released lot, SA-GH2-2610. Scan the QR code on the vial label to open its certificate. The lot number is also on your packing slip, and the full certificate is here.
Every certificate is issued by an independent laboratory. Each lot has its own public record page with every assay value, and a link to verify the report on the lab's own site once the signed PDF is posted.
Vials are filled slightly over the labelled mass so that every vial meets it. Net content is measured on each lot and published as a number, not a pass.
Email [email protected] within 7 days with your order number and a photo and we will replace it.
Orders by 2 PM ET on a weekday ship the same day, with tracking emailed when the label prints.
