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.
