In this episode of Biohacking Superhuman Performance with guest Dr. Amy Killen, we explore the world of stem cells - what they are, how they perform in the body, and how they work to increase longevity. Stem cell therapy is still being researched and regulated, but there is an amazing amount of potential for healing and increasing longevity with these powerful cells.    We also dive into exosomes - the small molecules that can penetrate places that stem cells can’t. Aesthetic procedures are popular with exosomes- they have the power to restore hair and rejuvenate skin, and are used in many skincare products. We even go over ovarian rejuvenation and Rapamycin, a potential prescription drug for delaying menopause.     Overall, this episode offers guidance on stimulating stem cells right in your own home. We talk through different tips such as supplements, fasting, and getting sun in a healthy way for those who aren’t in a place to budget for stem cell therapy.    Dr. Amy Killen is an outspoken advocate for empowering people to look and feel their best by merging lifestyle modification, integrative medicine, body-identical hormones, energy modalities, and stem cell therapies. She is the founder and CEO of the Human Optimization Project (HOP), a longevity-based subscription supplement company that stays on top of the science and constantly updates its ingredients for customers who can’t devote their lives to reading the latest research sourcing the best therapies.
