Good medicine starts with curiosity, but curiosity has to be grounded in evidence. Peptide therapy has grown fast, and so have the promises attached to it. Our job is to sort the hype from what the research actually shows.

Peptides are short chains of amino acids. Some have been used in medicine for years. Others are still being studied. You have probably seen them promoted for everything from healing injuries to slowing aging. This guide walks through the peptides getting the most attention, what the science says today, and how we think about them at Carencia Mental Healthcare. Our care brings together integrative psychiatry, psychotherapy, primary care, and preventive medicine under one roof.

Quick Look: What This Guide Covers

  • NAD+ supports cellular energy and healthy aging.
  • BPC-157 is studied for tissue and gut repair.
  • TB-500 pairs with BPC-157 as the “Wolverine Stack” for recovery.
  • MOTS-c is a mitochondrial messenger tied to metabolism.
  • Safety comes down to the source and the pharmacy behind it.

A Different Lens to Think About Health

Traditional medicine treats disease after it shows up. Think high blood pressure, diabetes, or heart failure. Preventive medicine asks a different question. How do we protect health before illness takes hold? That means looking at sleep, metabolism, inflammation, nutrition, movement, stress, hormones, and mental wellness together. This whole-person view sits at the heart of our functional medicine approach.

Peptides are joining that conversation. These signals can nudge specific pathways in the body. Some are proven. Many are still promising. Promising is not the same as proven, and we keep that line clear for our patients.

Why Mental Health Providers Care About Physical Health

Depression, anxiety, brain fog, and fatigue are often tied to physical problems. Think chronic inflammation, poor sleep, insulin resistance, and nutrient gaps. The link between body and mood is real, not a hunch.

About one in four people with depression show low-grade inflammation in their blood (Osimo et al., 2019). Raised inflammation can shift brain chemistry and mood (Miller and Raison, 2016). Supporting these systems does not replace therapy or medication. It may build a stronger base. Our general healthcare and primary care team works this way every day, serving patients in Fort Worth and Arlington.

The Peptides Getting the Most Attention

Here are the four peptides we hear about most, and what the research shows right now.

NAD+: Supporting Cellular Energy

Every cell uses NAD+ to make energy. It also supports DNA repair and shields cells from stress (Covarrubias et al., 2021). NAD+ drops as we age. Early human trials show boosters raise NAD+ safely, but they have not yet proven better memory or focus (Orr et al., 2024). For people with fatigue or low mood, NAD+ is not a standalone fix. It may support the energy systems underneath. See our post on creatine for mental health for a related idea.

BPC-157: The Repair Peptide

BPC-157 has drawn interest for tissue repair, gut health, and recovery after injury (Seiwerth et al., 2021). One honest caveat: almost all of this research is in animals, with no large human trials yet. Because chronic pain and inflammation often feed anxiety and poor sleep, better healing may help both body and mind. Gut health matters here too, as our post on the gut microbiome explains.

BPC-157 + TB-500: The “Wolverine Stack”

You may have heard BPC-157 and TB-500 called the “Wolverine Stack,” a nod to the comic hero and his fast healing. The science is more careful than that. Both are studied for supporting recovery, and most TB-500 evidence comes from animal wound-healing studies (Philp and Kleinman, 2010). Interest is strongest for people recovering from muscle or joint injuries, chronic pain, or slow healing.

MOTS-c: A Mitochondrial Messenger

MOTS-c is made inside the mitochondria, the tiny powerhouses in your cells. It acts like a messenger for how cells use energy, and it is studied for insulin sensitivity and metabolism (Lee et al., 2015). In mice it improved physical performance, and in people, exercise raises natural MOTS-c (Reynolds et al., 2021). Metabolic health and mental health are closely linked, as our post on metabolic syndrome shows.

What About the Way I Feel?

At Carencia, mental health does not stand alone. The brain is part of the body. How you sleep, move, heal, and make energy all shape how you feel. No peptide replaces proven psychiatric care. But easing chronic inflammation, pain, or low energy may make psychotherapy and mood disorder care work even better. We see these therapies as one possible part of a full plan, never a swap for it.

Our Philosophy at Carencia

We do not chase the newest trend. We treat the whole person, not just a diagnosis or a symptom list. That is why we combine psychiatric care, primary care, preventive medicine, and lifestyle support into a plan built around you. For one patient, that means therapy and medication. For another, an emerging option like peptide therapy may fit, when the evidence supports it and it matches your goals.

Quality, Safety, and Why the Source Matters

As interest in peptides grows, so do the products sold online. Many labeled “research peptides” are meant for lab use only, not for people. Without proper oversight, you cannot be sure of a product’s identity, purity, strength, or sterility.

Are Peptides Legal, and Can They Be Compounded?

Here is the honest picture. Most peptides are not approved by the FDA as finished drugs. Some can still be prepared by a licensed compounding pharmacy, but only when they meet FDA rules for compounding. That status is changing. In July 2026, an FDA advisory committee reviewed several popular peptides, including BPC-157, TB-500, and MOTS-c, to weigh whether they belong on the approved compounding list. Until the FDA finishes its review, we follow its guidance and prescribe only what our licensed pharmacy can prepare within the law.

The Grey Market vs. a Certified Compounding Pharmacy

Not all sources are equal. A large grey market now sells peptides online and through gyms, often stamped for research use only. Buying from a website, a social media seller, or the guy at the gym means no one has checked what is really in the vial.

Red Flags: Signs of a Grey-Market Peptide

  • Labeled “for research use only” or “not for human use.”
  • No prescription and no licensed provider involved.
  • Sold online, through social media, or at a gym.
  • No batch testing for dose, purity, or sterility.
  • A price that seems too good to be true.

A licensed compounding pharmacy is a different world. It holds state and federal licenses, follows Good Manufacturing Practices, and runs quality control on every batch. That is how we can trust that your medication matches its label and is safe to use. When peptide therapy fits your plan, this is the only way we source it.

Frequently Asked Questions

What is peptide therapy?

Peptides are short chains of amino acids that signal specific pathways in the body. Peptide therapy uses these compounds to support processes like tissue repair, cellular energy, and metabolism. Some peptides have long clinical use. Many others are still under study.

Can peptides treat depression or anxiety?

No. Peptides are not a treatment for mental health conditions. At Carencia, we use them only to support physical health that may affect mood, and always alongside proven psychiatric care, never in place of it.

Are peptides like NAD+, BPC-157, and MOTS-c FDA-approved?

Most peptides are not FDA-approved as finished drugs. Some can be prepared by a licensed compounding pharmacy when they meet FDA rules. The FDA is actively reviewing several popular peptides, including BPC-157, TB-500, and MOTS-c, so we follow its guidance and prescribe only what our licensed pharmacy can prepare within the law.

Why does it matter where my peptides come from?

A large grey market sells peptides online and through gyms, often labeled for research use only. Those products are not checked for dose, purity, or sterility. We prescribe only through a licensed compounding pharmacy that follows Good Manufacturing Practices and quality control, so you know what you are getting.

Is peptide therapy safe?

Safety depends on the source and whether it fits your health. We weigh the likely benefits against the risks for you, and we prescribe only through a trusted, licensed compounding pharmacy, never from unverified online or in-person sellers.
