The Keeps and Elite hormone therapy studies
The KEEPS Study
The Kronos Longevity Research Institute, a nonprofit organization in Phoenix devoted to aging research, is sponsoring the Kronos Early Estrogen Prevention Study (KEEPS).
The randomized, placebo-controlled study is scheduled to last five years.
The researchers plan to enroll 720 recently menopausal women. Participants must be age 42–58 and healthy. They can not have had a hysterectomy. And "recently menopausal" means having had a menstrual cycle in the last three years, but not having had one in the last six months.
