Why these vendors?
The vendors listed above have passed PeptiDex's rigorous verification standards. They provide transparent, third-party batch testing (COAs) utilizing both HPLC and Mass Spectrometry, ensuring that the GHK-Cu you receive is authentic and highly pure (>98%).
Because GHK-Cu is often sold as a research chemical, it is not subject to FDA manufacturing oversight. This means the market is flooded with under-dosed, impure, or completely fake products. We protect researchers by demanding transparency.
For a vendor to be listed on this page, they must provide a valid Certificate of Analysis (COA) from an independent, US-based analytical laboratory (like MZ Biolabs or Janoshik). This COA must prove that the GHK-Cu batch meets or exceeds 98% purity via High-Performance Liquid Chromatography (HPLC).
Amino Club and Bio Longevity Labs are highly rated sources for GHK-Cu, both offering independent COAs and fast shipping.
