In Part 2 of our peptide series, Nick and Alexis shift from body composition into peptides that support skin and hair rejuvenation, recovery, sleep quality, stress resilience, and immune performance. They break down how GHK-Cu (“the glow peptide”) may help with collagen, wound healing, and hair follicles; why TB-500 is often paired with healing protocols; and how Epitalon is discussed in longevity circles for its potential link to telomeres and circadian rhythm support.

They also explore sleep-focused DSIP and the Russia-developed nootropic Selank for anxiety and cognitive support—plus a deep dive on Thymosin Alpha-1, one of the most researched immune peptides, including its role in immune signaling and why it’s been studied alongside infections and serious conditions. The episode wraps with practical guidance on using peptides responsibly, avoiding “research-only” sources, and working with a qualified medical provider.

In Part 1 of this peptide series, Dr. Nick and Alexis Clark, PA break down what peptides are, how they work, and why safety and sourcing matter more than ever. With peptides exploding in popularity online, they explain the real science behind growth hormone–related peptides and how they affect lean muscle, fat loss, recovery, sleep, and overall body composition.

This episode focuses on peptides that stimulate your body’s own growth hormone production—such as Sermorelin, CJC-1295, Tesamorelin, Ipamorelin, IGF-1 LR3, and MOTS-C—including how they work, when they’re useful, how they differ from synthetic HGH, and why proper medical oversight is critical.

Dr. Nick also shares why ordering peptides online is dangerous, how mislabeled products can contain contaminants, and how these therapies are responsibly used in clinical practice to support metabolic health, aging, and recovery. This is a grounded, evidence-based introduction designed to cut through hype and misinformation.

Part 2 will dive deeper into additional peptides and advanced clinical applications.

Dr. Nick Gentry joins the People of Northwest Arkansas to break down what actually works when it comes to staying healthy during cold and flu season — and why so many common treatments miss the mark.

From his background in high-acuity emergency medicine to building a practice focused on root-cause, preventative care, Dr. Nick explains why most seasonal illnesses are viral, when antibiotics do more harm than good, and how supplements like vitamin D, vitamin C, zinc, and omega-based mediators can support immune function.

The conversation also dives into hormone replacement therapy, gut health, inflammation, sauna and cold-plunge science, wearable health tracking, and how modern lifestyle factors disrupt hormones far earlier than most people realize. Dr. Nick shares practical guidance for women and men navigating midlife health, fatigue, brain fog, weight changes, and recovery — without fear-based medicine or unnecessary prescriptions.

This episode is an informative, approachable deep dive into how to take ownership of your health and make smarter decisions for yourself and your family during the winter months.

Dr. Nick and Alexis Clark, PA-C, dive deep into the science of recovery—sharing practical, evidence-based ways to heal faster after surgery or injury. Drawing from Dr. Nick’s own back surgery experience, they unpack the role of high-protein nutrition, early mobility, and cutting-edge therapies like BPC-157, CJC-1295, and STEMREGEN. Learn how peptides, supplements, and smart pre- and post-op strategies can reduce inflammation, protect muscle, and accelerate your body’s natural healing process.

When viruses strike, your body’s immune system is your best line of defense—but the right supplements can make all the difference. In this episode, Dr. Nick and Physician Assistant Alexis Clark share evidence-based strategies for preventing and treating acute viral infections through targeted nutrition and supplementation.

They discuss how specific vitamins, minerals, and antioxidants can support immune resilience, shorten recovery time, and reduce the severity of symptoms. From vitamin D and zinc to quercetin and glutathione, learn which supplements truly work—and which ones aren’t worth your money.

What do sick dolphins have to do with human longevity? In this fascinating episode, Dr. Nick sits down with Dr. Stephanie Venn-Watson, co-founder of Fatty 15, to uncover how marine research led to the discovery of a new essential fatty acid—C15:0—that may hold the key to longer, healthier lives.

They dive into the groundbreaking science behind Fatty 15, its origins in dolphin health studies, and how this newly recognized fatty acid supports cellular resilience, heart and liver function, mood, and more. Discover why C15:0 is being called the “next generation omega” and how it could redefine the way we think about essential nutrients and aging.

Can small doses of GLP-1 medications do more than just support weight loss? In this episode, Dr. Nick explores the growing research behind microdosing semaglutide (Wegovy, Ozempic) and tirzepatide (Mounjaro, Zepbound)—and how these powerful peptides may help reduce inflammation, improve heart health, support brain chemistry, and even play a role in overcoming addiction.

You’ll learn what makes microdosing different from traditional protocols, how it may optimize metabolic health without major side effects, and what early evidence suggests about the future of GLP-1 therapy beyond weight management.
