in vitro testing is generally not recommended based on poor sensitivity
Its predictable degradation profile, stability, and reproducibility make it suitable for complex experimental designs
These models are validated by their ability to reproduce a diversity of new experimental results, and can be used as platforms for in-silico experimentation to determine the underlying mechanisms that give rise to the behavior seen in the clinic and experiments
The duration effect suggests GHK-Cu induces cumulative structural changes in dermal architecture where longer treatment allows more complete remodeling supporting ongoing enhanced function without continuous peptide presence
