  • To make this clearer, our team put together a quick-reference table. This summarizes the key differences you'll encounter when evaluating GHK-Cu quality real vs fake.
  • Appearance
  • Fine, solid, crystalline powder. A distinct, vibrant deep blue.
  • Clumpy, off-color (pale blue, grey, or white), moist, or overly voluminous.
  • Solubility
  • Dissolves readily and completely in proper reconstitution fluid, creating a clear, deep blue solution.
  • May not dissolve fully, leaving behind sediment, cloudiness, or floaters. Solution may be pale or colorless.
  • Vial & Labeling
  • Medical-grade glass, secure crimp cap, professional and clear labeling with batch number.
  • Cheap glass, loose cap, flimsy or poorly printed label with misspellings. Often lacks a batch number.
  • Documentation
  • Provides current, batch-specific Certificate of Analysis (CoA) with verifiable HPLC and MS data.
  • No CoA provided, or offers a generic, outdated, or doctored report. Refuses to provide testing details.
  • Supplier Reputation
  • Established presence, transparent sourcing, positive reviews from the research community, responsive support.
  • Anonymous website, untraceable origin, negative reviews (or suspiciously perfect reviews), no customer support.
  • Price
  • Priced in line with industry standards for high-purity synthesis.
  • Significantly and suspiciously cheaper than all reputable competitors. Price seems too good to be true.
