- 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.
