SHR # 2614 :: The Pep Talk: Oxytocin: The Most Anabolic Peptide Dr. Elizabeth Yurth, MD - The Pep Talk: Oxytocin: The Most Anabolic Peptide Dr. Elizabeth Yurth, MD - While people were still talking about oxytocin as the “love” peptide hormone that helps build bonds, improve mood, strengthen labor contractions during childbirth and help make breastfeeding easier, it was becoming evident to me that oxytocin was much more. From increasing a gut microbe that reversed aging in rats to making old muscle recover and heal like young muscle. Earlier this week on show 2610 we learned new information that oxytocin in the post-menopause model reverses osteoporosis! To add the final piece to this puzzle today we will discuss a study that points to all of the muscular gains experienced when using the strongest and harshest anabolic steroid in the world – Trenbolone – appears to be due to its ability to raise blood and tissue levels of oxytocin 50 fold! We will explore this and a few other effects of oxytocin that may make it one of the most important drugs for bodybuilding and performance enhancement in the world.
