Was the study conducted in cells, rats, mice or humans

There is no controlled human trial showing that Epithalon extends lifespan, prevents age-related disease or produces a clinically meaningful reduction in biological age

This early cosmetic enhancement proves encouraging but shouldn't be mistaken for actual dark circle reduction requiring substantially longer peptide treatment duration as described in SeekPeptides timeline guides

The FDA has established guidance documents specific to peptide drug development, addressing topics such as analytical characterization, manufacturing controls, and clinical development strategies
