AHK-Cu for Sale | Copper Peptide, 99%+ Purity | Nordiscience
What AHK-Cu Is
AHK-Cu (alanyl-L-histidyl-L-lysine copper complex) is a synthetic copper binding tripeptide structurally related to GHK-Cu, with the glycine residue in the original sequence replaced by alanine. Like GHK-Cu, it appears in the peer-reviewed literature on dermal fibroblast behavior, extracellular matrix signaling, and tissue remodeling research, and it is frequently discussed alongside GHK-Cu as researchers compare how substitutions in the peptide backbone may affect a copper complex's structural properties.
For researchers already working with copper peptides, AHK-Cu is typically evaluated as a related compound to GHK-Cu rather than a standalone discovery, which is why sourcing questions for the two compounds tend to look alike: can the supplier confirm what is actually in the vial, and can they back that confirmation with data.
Why Identity and Purity Verification Matter
A small tripeptide copper complex like AHK-Cu is straightforward to synthesize poorly and difficult to verify by appearance alone. Two checks matter most when qualifying a source.
Identity confirmation: mass spectrometry (MS) and/or HPLC data confirming the material matches the expected molecular structure, not just the label on the vial.
Purity quantification: a stated purity percentage backed by chromatographic data, not a bare claim on a product page.
Without both, a lab has no way to know whether a batch is research grade or whether it is introducing a confounding variable before an experiment even starts.
What a Real Certificate of Analysis Should Include
A Certificate of Analysis (COA) ties a specific batch to its test results. Before treating any COA as sufficient, check that it includes:
- Batch or lot number matching the product received
- Third-party (not just in-house) testing
- HPLC purity percentage
- Mass spectrometry identity confirmation
- Test date and testing laboratory name
A COA that is generic, undated, or not tied to a specific batch number is not a meaningful verification. It is marketing collateral.
Nordiscience's Sourcing Standards
Nordiscience sources AHK-Cu under GMP-following manufacturing protocols and independently verifies each batch through third-party lab testing. A Certificate of Analysis is available on request for every batch sold, including HPLC purity data and mass spectrometry identity confirmation, so researchers can verify what they are receiving before it reaches the bench.
AHK-Cu and GHK-Cu Side by Side
AHK-Cu and GHK-Cu are frequently sourced together by labs working across copper peptide research more broadly. For a closer look at GHK-Cu's own literature and sourcing considerations, see our GHK-Cu purity and sourcing guide. Both compounds sit in our Longevity and Anti-aging category, and both ship under the same purity and identity verification standard described above.
Built for Researchers Who Order Directly
Beyond the compound itself, Nordiscience is built around the practical friction points that slow down research procurement: standard credit card, Apple Pay, and Google Pay checkout with no crypto-only paywall, fast US shipping, and a support team reachable by email or WhatsApp for sourcing or documentation questions.
