Description
Most people do not see significant weight loss during this phase

Best For: Serums, toners, and leave-on products

The concept of peptide stacking becomes particularly relevant here, though any such approach should be guided by research and medical supervision

When researchers need a well-characterized copper tripeptide with robust published literature, GHK-Cu is the clear choice

Researchers across multiple scientific disciplines explore peptides to better understand cellular processes, biological mechanisms, and other areas of study
