The honest answer is that it depends entirely on your goals
These are short synthetic peptide sequences from families studied in laboratory research, including a copper-binding tripeptide (GHK-Cu), a tripeptide fragment of alpha-melanocyte-stimulating hormone (KPV), and two peptide fragments (BPC-157 and TB-500)
While other peptides may be more potent anti-inflammatory agents, few match GHK-Cu dual functionality
Researchers report changes that map to what users actually want to see: skin that looks thicker, firmer, smoother, and less crinkled ranking it among the best peptides for skin tightening
