MOTS-C: The Mitochondrial Peptide for Metabolism and Insulin Sensitivity 23.03.2026 14:55
MOTS-C is one of the most unique peptides being studied today — not because of what it does, but because of where it comes from . Unlike most peptides, MOTS-C is encoded inside your mitochondria , the part of the cell responsible for energy production. That makes it part of a growing category of mitochondrial signaling peptides that may play a role in metabolism, aging, and cellular energy regulat...
Do Growth Hormone Peptides Actually Work? CJC-1295, Ipamorelin & Sermorelin Explained 14.03.2026 22:51
Growth hormone peptides are some of the most talked-about compounds in longevity medicine, metabolic health, and hormone optimization. But how do they actually work inside the body? In this episode of Peptides Explained , we break down the science behind four growth hormone secretagogues: Sermorelin, Tesamorelin, CJC-1295, and Ipamorelin. Instead of injecting growth hormone directly, these peptide...
BPC-157 and TB-500 "The Wolverine Stack" 04.03.2026 25:57
In Episode 3 of Peptides Explained , we take a closer look at two of the most talked-about peptides in injury recovery circles: BPC-157 and TB-500 . These compounds are often combined in what’s popularly called the “Wolverine Stack,” a nickname that reflects claims of accelerated healing and recovery. But what are these peptides actually doing in the body, and what does the science really say? In...
GLP-1 Medications Explained: How Semaglutide, Tirzepatide, and Retatrutide Actually Work 26.02.2026 33:51
GLP-1 medications are the most talked-about compounds in modern medicine — and the most misunderstood. Most of the conversation focuses on weight loss results. Almost none of it explains the biology driving those results. In this episode of Peptides Explained, we break down the science behind three of the most prescribed GLP-1 compounds: semaglutide, tirzepatide, and retatrutide. Topics covered in...
What Are Peptides? The Building Blocks Behind Modern Therapeutic Compounds 22.02.2026 17:08
Peptides are everywhere in the health and longevity conversation right now — but most of what's out there skips the fundamentals. Before you can understand semaglutide, BPC-157, or any other compound making headlines, you need to understand what a peptide actually is at the biological level. In this episode of Peptides Explained, we lay the foundation: What peptides are and how they differ fro...
