Best-Of Lists for Your Second Act
Physician-informed best-of lists for adults over 45: what to measure, how to train, eat, sleep and recover, and how to buy peptides safely.
20 lists
Short, sourced lists for adults in midlife and beyond. Each one is written by the ACT 2 Health team from published guidelines and research, says where the evidence is thin, and links to the sources it relies on. A list carries a physician review line only after a named physician has read and confirmed it, as described in our editorial and medical review policy.
These lists are educational and are not medical advice. If something here applies to you, the next step is a conversation with a clinician, and measuring first.
Clinics and programs, compared
