10 Sep 2019 --- It might be possible to reverse the body’s epigenetic clock – the measure of biological age – according to a small clinical study published in Aging Cell. Nine healthy volunteers who took a cocktail of a growth hormone and two diabetes medications for a year shed an average of two and a half years from their biological ages, as well as having a rejuvenated immune system. Although the findings are preliminary, they could pave the way for new aging interventions, as well as showcasing how one form of medication could be used to treat multiple diseases.
