Our peptide range is built on biomimetic peptides rather than copper peptides

While systemic dihexa half life remains one to two hours, CNS concentrations may persist for four to six hours because the peptide is delivered to the target site without requiring blood-brain barrier penetration

Pineal Melatonin Rhythm in Elderly Humans Korkushko et al., Bulletin of Experimental Biology and Medicine (2004) Korkushko and colleagues at the Institute of Gerontology in Kiev evaluated the effect of the related pineal peptide preparation epithalamin (the longer parent compound from which Epithalon was derived) on circadian melatonin secretion in elderly human subjects

This helps to maintain its stability and prevent degradation
