The honest caveat: the only human results come from uncontrolled protocols that combine copper peptides with minoxidil and dutasteride, where the copper peptides independent contribution cannot be separated and the authors themselves note the lack of a control arm (Kuceki et al., 2025)

The brain ranks high in this hierarchy, being able to maintain relatively high selenoprotein expression under Se deficiency (Solovyev, 2015
