  • The table below compares research-grade GHK-Cu cosmetic to commercial GHK-Cu cream across formulation, regulatory, and practical use dimensions.
  • Molecular Active
  • Lyophilized GHK-Cu tripeptide, >95% purity verified by HPLC
  • GHK-Cu suspended in cream base with 10–20 additional ingredients
  • Same peptide; formulation complexity differs
  • Concentration Verification
  • Exact mg per vial documented; known molarity after reconstitution
  • Percentage listed on label without purity verification, or unlisted entirely
  • Research-grade provides dose control; commercial products often lack precision
  • Regulatory Classification
  • Research-use-only; not FDA-approved; no therapeutic claims permitted
  • Cosmetic product under 21 CFR 700; consumer-use intended
  • Different compliance pathways; research classification requires 'not for human use' labeling
  • Stability and Shelf Life
  • 24+ months at −20°C as lyophilized powder; 30 days refrigerated after reconstitution
  • 6–12 months from manufacture as sealed cream; degrades faster once opened due to multi-ingredient oxidation
  • Lyophilized form offers superior long-term stability
  • Documentation Provided
  • Certificate of analysis, HPLC purity, mass spec, endotoxin testing
  • Ingredient list; no batch-specific analytical data
  • Research-grade includes reproducibility data; consumer products do not
  • Typical Use Case
  • In vitro cell culture studies, ex vivo skin models, formulation development research
  • Direct topical consumer application for skincare
  • Research-grade supports experimental control; creams are finished consumer products
  • This comparison clarifies why the question 'is GHK-Cu cream same as GHK-Cu cosmetic' depends on context. For molecular biology, they're identical. For practical research use, they're not interchangeable.
