Model: Male Wistar rats (4-month-old young rats and 24-month-old old rats)
Dosage: Oral administration of the trypsin inhibitor tranexamic acid in drinking water for 14 days at a minimum dose of 0.39 g/kg/day after consuming about 40 mL/day of water

Newly Proposed Aging Mechanism: Digestive Enzymes May Be Eating Us from Within

University of California, San Diego researchers show digestive enzyme leakage from the intestines contributes to organ damage in old rats, offering what may be a new way to explain aging.

Model: 16-month-old female C57BL/6 mice 
Dosage: 60 mg/kg/day of ABT-263 dissolved in drinking water for 7 days on, 7 days off, and 7 days on again

A senolytic compound and anti-cancer drug called ABT-263 accelerates ovarian aging in aged mice, suggesting it promotes infertility.
