Molecule Reverses Muscle Aging
in Mice. This from geneticist David Sinclair who, along with his team, injected NMN into mice and: " we fed ... the old mice - the equivalent about a 60-year-old human - we fed them a molecule that's called NMN and this reversed ageing completely within just a week of treatment in the muscle, and now we're looking to reverse all aspects of ageing if possible."
Its worth noting that one of the mice prematurely aged, and how do you prematurely age an old mouse anyway? Sinclair kinda avoids talking about that point here.
