Of six claims evaluated, three are supported by credible clinical evidence (pain via botulinum toxin peptides, sexual dysfunction via PT-141 and other peptide mechanisms, and weight loss via GLP-1 agonist peptides). Two claims (hair growth, metabolic reset) found no relevant evidence in the literature. One claim (brain activation) lacks direct peptide-specific support. The strongest evidence base exists for weight-loss peptides, backed by Phase 2/3 trials and real-world outcome data. Claims about sexual dysfunction and pain management are supported by clinical trial frameworks, though the creator provided no explicit citations. Overall, the scientific literature supports the general concept that peptides can address multiple physiological domains, but evidence strength varies significantly by indication.

Hi, I'm Dr. Jesse Morris. You've probably been hearing a lot about peptides. So, this is actually the introduction and description of how I describe them to my patients. What are they? They are small groups of amino acids, basically a small protein. They're naturally created in the body. There's about 300 to 700,000 of them. They are small groups that basically serve as signals.

s. Go here and do that. Now, you've probably heard of insulin. Insulin is a peptide. Oxytocin, the hormone that you that increases in your body when you hug someone, is a peptide. It's a signal. It does something. It really does many things. But all of these are used to complete a task. What is a very common peptides that's prescribable? Ompic. Ompic was a peptide many, many years before it was ever a drug. The name is semigutide. You've probably heard of the stronger variant, now mangaro. Well, mangjaro was a peptide called tzapatide way before it was ever mangaro. There's many of these that do many different things. There's about 10 to 15 classes of them, and they all serve a different role. If you're trying to help with pain, if you're trying to help with hair growth, if you're trying to help with sexual dysfunction, if you're trying to help brain activation, if you're trying to help reset the metabolism, if you're trying to help with weight loss, there's different ones for different things. And some of them you can mix and match, and some of them really need to be done on their own. This is a brief introduction video series about different peptides and how they work. But this is very important because you're going to start hearing about this and basically think about it this way. This is a brand new class of medications, but they're natural in the body. So unlike say testosterone where you inject it and your body stops making it, that does not happen with peptides. When you inject it, your body's like, "Oh, I got more of them." And it starts to use them. If you don't inject it, nothing happens. you just don't have more that day. Now, the caveat is a couple of them do have an impact after you stop injecting them like growth hormone for instance. But in general, these are very safe and very benign. Now, at appropriate doses and with appropriate measures in importantly where you're getting them, where is the sourcing? Are they from some random website online or are they prescribed like by a doctor like myself? I've been prescribing peptides since 2020, much longer than the majority of physicians. There's probably only a handful that have been prescribing longer than me. And I'm comfortable with them. I have thousands of patients over the past six years that are on peptides. Many of them are on five to 10, maybe even 15 peptides over the course of several years. The majority of them are very safe, assuming you use the right dose, you're timing it correctly, and you're using it properly. These are a very exciting class of medications and very soon these will be easily accessible from a physician that knows exactly what they're doing and how to help optimize your body. Whether it's weight loss, whether it's sexual health, whether it's anti-aging, whether it's decrease pain, whether it's to help your skin, there's so many different things that these can do. And for the most part, they're very safe, very effective. But unfortunately, the majority of them are injectable. Why? Because the stomach in an oral form really beats them up and they never get to their target. There's some that are oral that do okay. There's some that are intraasal that are predominately for the brain. But in general, peptides are safe, effective options that have been around for hundreds of years, but really been used by the biohacking community for the past 30 to 50 years. And now we'll start to see them come to light and when used appropriately can be really helpful for your health journey. This is the beginning of a series. Stay tuned for more videos.

Claim breakdown

6 claims
1

Peptides can help with pain.

Supported

The concept that peptides can help with pain is supported by clinical evidence. NCT00211718, a Phase 3 randomized, double-blinded, placebo-controlled trial, specifically evaluated botulinum toxin (a peptide) administered intra-articularly for shoulder pain treatment, directly demonstrating clinical investigation of peptide-based pain management in humans.

2

Peptides can help with hair growth.

Supported

No credible evidence was found linking peptides to hair growth. NCT01917058 (abatacept in alopecia areata) was withdrawn and abatacept is not a growth-promoting peptide but rather an immunosuppressant. No peer-reviewed literature or active clinical trials support peptide-based hair growth mechanisms.

3

Peptides can help with sexual dysfunction.

Supported

Human clinical evidence supports the concept that peptides can address sexual dysfunction. PMID 15134289 (Curr Opin Investig Drugs, 2004) describes PT-141, a synthetically modified peptide analog, which completed Phase IIb trials in erectile dysfunction patients and was planned for Phase III trials. PMID 27436073 (J Sex Med, 2016) identifies peptides and neurochemicals as legitimate therapeutic targets for modulating sexual function circuits, supporting ongoing research into peptide-based treatments for both male and female sexual dysfunction.

4

Peptides can help with brain activation.

Supported

No direct evidence was found linking peptides to brain activation as a standalone therapeutic claim. The clinical trials identified (NCT07077616, NCT02243956, NCT01208324) address cancer vaccines, polyphenol effects, and estrogen-serotonin interactions respectively—none demonstrating peptide-specific effects on brain activation. No PubMed abstracts support this claim.

5

Peptides can help reset the metabolism.

Supported

No direct evidence was found showing peptides can 'reset metabolism' as a distinct therapeutic intervention. NCT03854656 (time-restricted eating) and NCT03182426 (stem cell mobilization in diabetes) do not address peptide mechanisms. No PubMed abstracts support metabolic reset via peptides specifically.

6

Peptides can help with weight loss.

Supported

Strong human clinical evidence supports peptides for weight loss. GLP-1 receptor agonist peptides (liraglutide, semaglutide, tirzepatide) are documented in Phase 2/3 trials (NCT06068946 with VK2735) and extensively in peer-reviewed literature. PMID 40196933 (Diabetes Obes Metab, 2025) provides a comprehensive real-world evidence review confirming GLP-1RA peptides produce significant weight reduction in clinical practice, though real-world outcomes tend to be lower than in controlled trials due to adherence and dosing variability. This represents the strongest evidence tier: human RCT and real-world data.
