Model: Young C57BL/6J mice fed a high protein (56% of daily calories) diet for 20 weeks 
Dosage: Injection with either 400 mg/kg of NMN or 20 mg/kg of 78c for 4 weeks

High protein intake improves the body composition of aged mice, but it lowers NAD+ (nicotinamide adenine dinucleotide) levels and promotes metabolic aging.

Model: 24-month-old female Sprague Dawley rats
Dosage: Undisclosed doses of pig-derived exosomes were injected into the rats every-other-day for eight days starting at day 1 and recommencing at days 68, 181, 280, and 377

Nano-Sized Vesicle Infusions Break Rat Lifespan Record

Nano-sized vesicles called exosomes derived from pig blood plasma significantly extended rat lifespan and broke the record for the longest-living rat.
