Hair loss can wreck confidence—and misinformation is everywhere. Dr. Nick and Alexis Clark, PA break down the biggest causes of hair loss (male vs. female pattern thinning, telogen effluvium, postpartum shedding, GLP-1 weight loss shedding), what to do first (nutrition, protein, supplements), and the treatments that actually move the needle: minoxidil, DHT blockers like finasteride/saw palmetto, PRP, microneedling, red light therapy, and more. They also cover timing—why waiting can cost you options—and when a hair transplant becomes the only real fix.

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.
