Ghrelin agonists
Pure substance principle Only active ingredients (without excipients, without colouring, by law without preservatives, no technological additives such as binding or anti-caking agents, no hidden additives)
Studies with aged mice demonstrated several improvements, including restoration of fur density, improved kidney function, increased physical activity (including running), and overall improvements in age-related frailty markers
