Model: C57BL/6 mice
Dosage: 500 mg/kg/day of SRN-901 via oral gavage for six days per week starting at 18 months of age; 14.4 ppm of rapamycin mixed in food starting at 18 months of age; 300 mg/kg/day of NMN via oral gavage for six days per week starting at 18 months of age; and 300 mg/kg/day of NR via oral gavage for six days per week starting at 18 months of age

Seragon Publishes Record-Breaking SRN-901 Longevity Data, Demonstrating 33% Lifespan Extension in Mice

In a newly published mouse study, SRN-901 extended remaining lifespan by 33%, slowed frailty progression, and lowered tumor incidence.

Seragon’s SRN-901 extended the remaining lifespan of adult mice by 33%, attenuated frailty progression by 70%, and reduced tumor incidence by 30.53%, according to a newly published preclinical study.

Changes to Bryan Johnson’s updated 2026 supplement stack include taking NMN or NR six days a week instead of seven and removing rapamycin.

Participants: Older adults with elevated HbA1c
Dosage: Nicotinamide (250 mg), palmitoylethanolamide (600 mg), oleoylethanolamide (400 mg), and spermidine (8 mg)

Supplement Combo that Mimics Fasting Counters Aging

In older adults, the combination of nicotinamide, palmitoylethanolamide (PEA), oleoylethanolamide (OEA), and spermidine counters cardiovascular and metabolic aging.

Clinical Trials

Model: 14- to 15-month-old male C57BL/6J mice
Dosage: 50 mg injection of 3′-deoxyadenosine (cordycepin) because it was shown not to be absorbed if administered orally

Mushroom Compound Prolongs Lifespan If Taken At Correct Time

In mice, cordycepin—a molecule found in cordyceps mushrooms—prolongs lifespan and improves memory, strength, cardiac function, hormone levels, and metabolism.

Model: 11-month-old male C57BL/6J mice 
Dosage: 30 mg/kg/day of NTX-748 (based on a small molecule called 78c) for 4 months, administered orally

Blocking NAD+ Breakdown Improves Cognitive and Physical Performance

Buck Institute scientists find that blocking the CD38 enzyme, which elevates NAD+ (nicotinamide adenine dinucleotide), counteracts age-related cognitive and physical decline in mice.
