[Emergency Pod] Peptides - Part 2 with Dr. Jonathan Slotkin of Scrub Capital

In this special episode of Lifers, Christina Farr sits down with Dr. Jonathan Slotkin (neurosurgeon, CMO, and co-founder of Scrub Capital) for a timely conversation on peptides and what the latest HHS announcements mean for patients and the longevity industry. Jon breaks down his own protocol, makes the case that the longevity conversation has too often left women out, and closes with a watch-out for investors: the potential descheduling of testosterone and what it could unlock for telehealth.
