    Using Peptides to Help Master Love, Sex & Intimacy

    Your libido isn’t gone—it’s just waiting for the right support. In this episode of Peptides & Longevity, Dr. Nick Delgado joins us to dive into the science and practice of creating a fulfilling sex life that lasts well into later years. From communication and intimacy strategies to hormone optimization and peptide therapy, he shares practical ways to boost vitality, intimacy, and longevity. In this episode of Peptides & Longevity, Dr. Nick Delgado challenges cultural myths and common misunderstandings about sexual health, intimacy, and performance. He explains that while 95% of men believe they are great lovers, the majority of women report not experiencing orgasm in their relationships—a disconnect rooted in lack of communication, inadequate foreplay, and male insecurity. Drawing on decades of research and clinical practice, Dr. Delgado emphasizes that true intimacy depends on dialogue, patience, and understanding women’s unique physiology. Beyond the bedroom, he explores how lifestyle and science intersect to extend both sexual vitality and life itself. He outlines the importance of hormone optimization, detoxification of harmful estrogens, plant-based nutrition, adrenal support, and the use of certain peptides. These tools, he argues, not only enhance sexual performance but also improve longevity, immune function, and quality of life. The conversation is both entertaining and deeply educational, offering actionable strategies for couples and individuals seeking to feel younger, healthier, and more connected.

    Microbiome, Mycology, and More!

    Discover how your gut’s microbial balance affects everything from stress to drug absorption. In this episode of Peptides & Longevity, Afif Ghannoum joins us to unpack the science of the gut microbiome and reveals how imbalances in this ecosystem can disrupt digestion, drug effectiveness, stress response, and immunity. In this episode of Peptides & Longevity, Afif Ghannoum, a biotechnology entrepreneur, breaks down the emerging science of the total microbiome—including bacteria, fungi, and viruses—and its massive impact on digestion, disease, drug response, and overall health. He shares insights from his father, Dr. Mahmoud Ghannoum, who coined the term ‘mycobiome’ and has led groundbreaking research into how fungi and bacteria form biofilms in the gut, driving inflammation and digestive disorders. Together, they developed BIOHM Health to bring this research to consumers with innovative testing and probiotic solutions. Afif also reveals surprising truths—like how stress, over-exercise, and restrictive diets can damage the microbiome, and how fungi aren’t inherently bad but vital to gut balance. He explains why prebiotics (dietary fibers that nourish good microbes) may be more important than probiotics alone, and how proper microbial balance affects pain, stress response, immunity, and even medication effectiveness. This is a powerful conversation for anyone who’s struggled with gut issues, chronic symptoms, or confusion about which ‘health rules’ to follow.
