Peptide therapy has taken the wellness world by storm in recent years, and today it’s more popular than ever before. As part of this trend, we’re also seeing the growth of peptide stacking: combining complementary peptides for even better results. 

In my functional medicine telehealth practice, I’ve worked with peptides for several years. One thing I’ve noticed, and this happens when the use of any wellness tool becomes more widespread, is that some people who promote peptides have lost the nuance that it takes to create real and sustainable transformation. 

Done thoughtfully, peptide stacking can be a powerful tool. Done haphazardly, it can become just another form of overwhelm or a band-aid strategy. 

So I wanted to tell you about peptide stacking through a functional medicine lens, including the benefits of different types of stacks, how they work, and how we approach this tool as part of a root-cause focused strategy for long-term health. I’ll also tell you about my new Functional Peptide Program, which is the only peptide therapy program built on a functional medicine foundation. 

An Overview of Peptides and Peptide Therapy  

Peptides are small chains of amino acids that send signals to your cells in order to effectuate and support biological processes related to immune function, tissue repair, hormone balance, metabolism, energy production, cognition, and beyond. 

The body naturally produces thousands of different kinds of peptides, and we naturally have receptors on our cells that respond to those different kinds of peptides. (1) But sometimes that cellular communication breaks down, causing important physiological processes to stall or slow down. This is when peptide therapy can be helpful. (2) 

Peptide therapy involves introducing exogenous (derived from external sources) peptides into the body to mimic the natural actions of our endogenous (produced within the body) peptides. Peptides used therapeutically are designed to bind to specific cell receptors and trigger the specific responses that have slowed down. 

Depending on the type of peptide and other factors, peptide therapy may involve the use of oral supplements, topical creams or gels, injections, transdermal patches, or other delivery forms including sublingual or intranasal. 

Popular peptides used therapeutically in different ways include BPC-157, semaglutide, GHK-Cu (copper peptide), collagen, spermidine, KPV, and TB-500. 

There are several possible benefits of peptide therapy for healthy aging, autophagy (cellular cleanup) metabolism and weight management, cognition, immune system function, inflammation regulation, fitness and performance, injury recovery and wound healing, skin health, hormone balance, and beyond. (3 – 8) 

But it’s all about how you use them: peptides should ideally help enhance cellular communication and stimulate biological processes, while we also work on healing any underlying imbalances that have caused natural cellular signaling to fall off. It’s the combination of the two that helps us truly thrive. In other words, peptides can give us a powerful boost, but it’s up to us what we do with that boost. 

How Does Peptide Stacking Work? 

Peptide stacking involves combining two or more different peptides that may complement, multiply, or support each other’s benefits. 

Peptides work by enhancing communication and restoring signaling pathways that may have become dysfunctional because of chronic stress, inflammation, hormonal imbalances, gut imbalances, or metabolic issues. And the reality is that very few people are struggling with just one isolated signaling pathway. 

Because everything in the body is interconnected, what we see clinically is that where there’s metabolic resistance, there’s also inflammation. Where there’s hormonal dysregulation, there’s often a gut microbiome imbalance. Where there’s immune system dysregulation, there are often skin issues

Peptide stacking allows us to address multiple bottlenecks at once, especially when stacks are intentionally designed to work on synergistic pathways. 

And because of the overlap of certain pathways, peptide stacking also often allows us to use lower doses of individual peptides. 

A Functional Medicine Perspective On Peptide Stacking 

I’ve seen incredible results with peptide stacking when it comes to restoring healthy metabolism, recovery, immune system function, gut health, skin health, and more. From a functional medicine perspective, the key is to work with the body’s natural healing systems and processes, not to try to override them. 

There are a few important things I always keep in mind when peptide stacking. The first is to always be thoughtful and strategic with a stack. More isn’t always better; we want to focus on where your biological roadblocks are, which peptides are likely to be the most effective, and how they will work together. Along these lines, instead of looking for rapid, dramatic results, I aim for gradual, meaningful improvements that last. 

And, of course, it’s absolutely essential to identify and address underlying imbalances and other issues that are causing impaired cellular signaling in the first place. By using peptide stacks strategically and with restraint, and simultaneously healing and restoring the body’s natural communication, we see the biggest health benefits over the long term. When natural function is restored, peptides can be tapered off. 

Supplement Guide

In my telehealth clinic, I’m often asked about supplements—what to take, why, and which brands are best.

Precision Peptide Stacking + Benefits

There are endless possibilities for peptide stacking combinations, but I like to keep it simple with what I’ve seen be most effective with my functional medicine telehealth patients. Here are a few of my favorite peptide stacks, and why and how they work. 

Glow and Klow Stack

This stack includes TB-500, KPV, BPC-157, and GHK-Cu. I love this combination because it supports inflammation regulation, tissue repair and recovery, and skin health, reflecting the fact that our skin health is a reflection of our internal health

Chronic inflammation, tissue damage, and skin concerns are often part of the same clinical picture, and these peptides work together to support: 

  • Healthy inflammatory signaling
  • Tissue repair and recovery (9) 
  • Collagen production and skin barrier integrity
  • Gut-skin and immune-skin communication 

GLP-1 and GIP Compounded Support

Metabolic dysfunction is one of the most misunderstood issues I see clinically. Weight loss resistance (when the body just doesn’t respond to diet and lifestyle changes) and blood sugar dysregulation often occur because of impaired metabolic signaling, and this is where GIP and GLP-1 receptor agonists come in. 

By now I’m sure you’ve heard of the GLP-1 receptor agonist semaglutide (sold under the names Ozempic and Wegovy) and likely the dual GIP/GLP-1 receptor agonist tirzepatide (sold under the names Mounjaro and Zepbound). 

There’s a lot of confusion about these, too. While I don’t recommend long-term, mega doses of these medications or using them like magic pills for rapid weight loss, long before the Ozempic craze I was using small doses of semaglutide to help kickstart metabolism for those who had tried everything else. 

When used responsibly, in conservative doses, and in combination with more comprehensive, whole-body support, this stack can be incredibly helpful for providing targeted metabolic and energy support. 

Stacked Combinations 

The chronic inflammation addressed by the Glow and Klow Stack and the metabolic dysfunction addressed by GLP-1 and GIP receptor agonists frequently go together. Using the two stacks in combination can help to enhance metabolic function, improve skin health, and reduce inflammation. 

These are a few of my favorites, but they’re not the only ones I work with. Other peptides can be stacked to support cognition, performance, and other goals. 

Who Is Peptide Stacking Right For? 

While peptides can help to optimize health in many ways and at different stages in a wellness journey, I recommend peptide stacking especially for those who are feeling stuck. 

For example, if you feel like you’ve tried every healthy eating plan and fitness program out there, and you haven’t seen any meaningful differences in your body composition. Your skin just won’t clear up. You don’t seem to recover as easily as you used to from exercise. You never seem to have the energy you feel like you should have. 

These are all signs of a signaling problem that can likely benefit from an intentional peptide stacking strategy. 

Peptide stacking is also best for those who are motivated to keep working on their healing holistically. While it’s certainly possible to use peptides in a “quick fix” kind of way, this isn’t an approach I recommend. 

There are some people who shouldn’t take peptides or shouldn’t take certain kinds of peptides. This includes those with certain kinds of medical conditions and those who are taking certain medications. Some individuals may require closer monitoring and more frequent testing when taking peptides, such as those with diabetes or certain kinds of hormonal imbalances. It’s always best to speak with a healthcare provider before starting or modifying a peptide protocol. 

Why I Created The Functional Peptide Program 

As I mentioned earlier, the Functional Peptide Program is the only peptide therapy program that’s built on a functional medicine foundation. This is a membership program that helps you use peptides and peptide stacking as tools within your toolbox to restore metabolic efficiency, reduce fatigue and inflammation, and feel like yourself again.

But the program goes beyond peptides, providing a precise yet personalized functional medicine framework for supporting and optimizing whole body wellness. 

The Functional Peptide Program includes a 4-phase metabolic healing roadmap, personalized nutrition and supplement plans, peptide protocol access, recipes and metabolism-friendly templates, hormone, stress, and sleep optimization tools, community support and coaching, and live monthly Q&A calls with me. 

I built this program because I wanted more people to be able to achieve benefits like increased energy, improved recovery, and enhanced metabolism, but to have the support and resources needed to achieve these benefits sustainably, safely, and without the overwhelm.

A Thoughtful, Precise Approach to Peptide Stacking 

When it comes to peptides, it’s not just about the tool but about how you use it. Peptide stacking, when approached thoughtfully and with clinical strategy, can help support profound healing. The key is to still keep asking what’s driving impaired cellular signaling and recovery, and to work with your body to restore natural function at the same time.
