Peptides 101: What High-Achieving Women Should Know

Peptides are everywhere in the health and wellness conversation right now, and Kim Abrego believes they deserve a place in it early. Within the Endura Method, the goal is always to find the behaviors and tools that give high-achieving women the biggest return for their effort, and Kim sees the right peptides, chosen for the right goals, as one of those tools. In this episode, she lays out the fundamentals.

A peptide, Kim explains, is simply a short chain of amino acids (proteins are the long chains) that acts as a signaler in the body. Insulin is one: it tells your body to start storing sugar when blood glucose is high. The collagen in your coffee is one. And so is a GLP-1, short for glucagon-like peptide, which surprises a lot of people. But being a peptide says nothing about safety or approval. Kim describes three tiers: FDA-approved peptides you get through a prescription, compounded versions made by pharmacies (where quality depends on the pharmacy), and gray-market peptides labeled “for research purposes only,” which carry the most risk because they may never have been third-party tested.

Kim then walks through the three GLP-1s people talk about most. Semaglutide works on the fullness signal, reducing hunger and “food noise.” Tirzepatide adds a second gut hormone, GIP, which seems to reduce nausea. Retatrutide, not yet FDA approved, adds a third component, glucagon, which Kim says raises energy and helps the liver burn more fat, including visceral fat, the fat around your organs that is especially harmful to health.

Her most important point, though, is about behavior. When people take a GLP-1 without changing how they eat or move, and then stop, the weight comes back. “Well, no kidding,” Kim says. “You didn't change anything.” The Lift pillar behaviors still have to be in place. The same goes for muscle: weight loss, with or without a GLP-1, typically comes with muscle loss unless you prioritize high protein and resistance training. Because GLP-1s reduce appetite, the calories you do eat need to be high quality. Kim recommends a DEXA scan every quarter to track what's actually happening to your body composition.

Beyond weight loss, Kim introduces peptides you'll hear about for other goals: the “Wolverine stack” (BPC-157 and TB-500) for tissue repair and inflammation; Glow and Klow, which build on that stack with copper and KPV; MOTS-C and SS-31 for mitochondrial energy; Semax and Selank for focus and brain fog; and DSIP for sleep. Her caveat: “These are not a substitute for poor behavior. These are to augment what you're already doing.”

Finally, Kim covers how to approach peptides safely. Most are injected with a very small needle, and she finds the fear usually fades after the first one. Match your choices to your risk tolerance, get baseline labs, and have someone help you monitor your health. Add one peptide at a time so you know what's working and what's causing any reaction. And be aware of peptide cycling, a common but still-debated practice, since so much of this is new and not yet backed by large official studies.
