peptides
Peptides are rapidly emerging as one of the most fascinating areas of health and wellness. These small chains of amino acids occur naturally throughout the body, where they act as important biological messengers involved in an extraordinary range of functions — from cellular communication and tissue repair to metabolism, immune activity, neurological function, and healthy aging.
What makes peptides particularly intriguing is their specificity. Different peptides can deliver very different signals, essentially providing instructions that influence how cells and tissues respond and function. As research continues to uncover these signaling pathways, peptides are opening new possibilities for supporting the body in remarkably targeted ways.
But the expanding world of peptides also brings plenty of questions. What exactly are peptides? How do they work? How are they administered? What does the research tell us about their potential benefits and safety? And with peptide products now appearing from so many sources, how can quality, purity, and appropriate use be evaluated?
This page is dedicated to exploring those questions and the evolving science behind the wondrous world of peptides.
What are peptides? How do they work? Why are we hearing so much about them — and what should someone know before considering their use?
Join me, Rebecca, & Krista Montrone of Wondrous Roots for a fascinating conversation with Garrett Gipe, one of the founders and co-owners of Theratide USA as we explore the rapidly growing world of peptides.
We discuss the fundamentals of peptide science, how peptides act as signaling molecules within the body, different methods of administration, safety and dosing considerations, current research, and some of the potential applications that have generated so much interest in peptide therapy.
We also tackle an especially important subject in today's peptide marketplace: quality. What do purity and potency really mean? How important are manufacturing standards, independent testing, sterility, storage, and sourcing? And how can someone begin to distinguish a quality peptide product from the enormous number of products now appearing online?

PEPTIDES 102: EXPLORING RETATRUTIDE & KPV
The deeper I get into the world of peptides, the more fascinating it becomes!
For Peptides 102, my daughter Krista Montrone and I sat down once again with Garrett Gipe of TheraTide USA to continue the conversation we began in Peptides 101.
This time we took a deeper dive into two peptides that have especially captured my attention through my own research: RETATRUTIDE and KPV.
And as you'll quickly discover, this conversation is about MUCH more than weight loss.
RETATRUTIDE: MORE THAN THE BATHROOM SCALE
We begin by looking at what makes retatrutide different from the GLP-1 therapies most people have heard about.
Semaglutide targets GLP-1. Tirzepatide adds GIP. Retatrutide adds a third component: activity at the glucagon receptor.
That third component led us into a fascinating discussion about energy expenditure and metabolism, including what distinguishes retatrutide from earlier GLP-1 approaches.
But that's really where our retatrutide conversation begins—not where it ends. We explore the much broader interest in retatrutide for metabolic health and inflammation, touching on areas such as blood sugar and A1C, fatty liver, cardiovascular and metabolic markers, fibromyalgia, osteoarthritis, PCOS and other areas being explored.
We also discuss something that particularly intrigues me: the idea of very small amounts of retatrutide as part of a broader wellness approach—even for someone who isn't looking for dramatic weight loss. Could retatrutide someday be thought of as another tool in the wellness toolkit? That's one of the questions we explore.
MICRODOSING AND AN INDIVIDUALIZED APPROACH
Naturally, that brought us to dosing and microdosing.
Garrett explains why there isn't necessarily a one-size-fits-all approach and shares some of what he has observed among people using very small amounts of retatrutide. We also discuss consistency, individual response and why introducing peptides gradually can make it much easier to determine what is actually producing a result.
As Garrett puts it, slow and steady can be a very useful philosophy when entering the peptide world.
And throughout that discussion, we come back to something that has always been foundational at Wondrous Roots: peptides don't replace the basics.
Adequate protein—particularly as we age—remains tremendously important. So does using our muscles. A peptide isn't a substitute for good nutrition, exercise and the other fundamentals of health. It is another tool that may work alongside that foundation.
THEN THERE'S KPV...
"KPV may consist of only three amino acids, but don't let its size fool you!"
Garrett describes four major areas of interest surrounding KPV:
• Anti-inflammatory activity
• Gut and intestinal health
• Skin and wound healing
• Antimicrobial activity
That immediately brought us into inflammatory bowel conditions.
KPV (Lys-Pro-Val) is a naturally occurring tripeptide derived from alpha-melanocyte-stimulating hormone (α-MSH) that is being investigated for its potent anti-inflammatory effects, particularly within the gastrointestinal tract. Research suggests that KPV can help quiet inflammatory signaling by inhibiting pathways such as NF-κB and reducing the production of pro-inflammatory cytokines, including TNF-α, IL-1β, and IL-6. Of particular interest for intestinal disorders, KPV appears capable of acting directly at the intestinal epithelium, where it may help reduce mucosal inflammation and support restoration of normal barrier function. Experimental studies have demonstrated benefit in models of inflammatory bowel disease and colitis, making KPV an intriguing research compound for conditions characterized by chronic intestinal inflammation, including Crohn’s disease, ulcerative colitis, and potentially other inflammatory forms of colitis. Human clinical evidence remains limited, however, so its application to these conditions is still investigational.
SKIN, WOUNDS—AND THE FIRST-AID KIT?
Our KPV discussion then moves beyond the intestinal tract.
KPV (Lys-Pro-Val) is also being investigated for its anti-inflammatory effects in the skin, where it may help calm excessive immune signaling without broadly suppressing normal immune function. Research suggests that KPV can inhibit NF-κB activation and reduce inflammatory cytokines such as TNF-α, IL-1β, and IL-6, mechanisms relevant to a variety of inflammatory skin conditions. It has shown particular interest for reducing inflammation, redness, irritation, and inflammatory responses involving keratinocytes, while its antimicrobial activity may offer an additional advantage when disruption of the skin barrier is involved. These properties have made KPV an intriguing research compound for conditions such as psoriasis, eczema/atopic dermatitis, inflammatory rashes, and wound-related inflammation. Early experimental research also suggests potential support for tissue repair and wound healing, although human clinical research remains limited and KPV should still be considered investigational.
