What Are Peptides And How Are They Used In Medicine Today?

It is more important than ever to find ways to optimize health and maximize performance. With the daily pressures many of us face, we can’t afford to be anything less than our best. As a result, an increasing number of people are looking for treatments that will help them improve their health, perform better at work, and even slow the signs of aging.

While there are hundreds, if not thousands of options offered, few treatments are as exciting or promising as peptide therapy. Let’s define peptides, their various types and functions, and how they can be used in medicine today.

What are Peptides?

A peptide is a sequence of two or more amino acids1 linked together. There are two main types of peptides.

Natural Peptides

These are made by the body, and you can find them in foods like eggs, milk, and fish. They are created by enzymes that break down proteins in food into smaller peptide chains. These peptides have a wide range of functions in the body, including acting as hormones, neurotransmitters, and growth factors. They are important for many bodily functions, like cell communication, metabolism, and the immune response.

Synthetic Peptides

These are created in a laboratory. They are usually designed to mimic the structure and function of natural peptides and are often used in research, cosmetics, and medicine. Synthetic peptides are easier to make in large quantities and can do specific jobs better than natural ones.

Peptides can be divided into several classes based on their size and structure, such as small peptides, oligopeptides, glycopeptides, and macropeptides.

How are Peptides used in Medicine? 

Scientists have found that peptides have many useful properties. Let’s take a look at how they operate within medicine today.

Treatment of Diabetes Insipidus

Diabetes insipidus is a hormonal condition in which the body produces an abnormally high volume of urine, which in turn causes the affected individual to feel thirsty and dehydrated. The condition may be treated with medications such as Vasopressin, a peptide hormone.

Vasopressin2 causes the kidneys to excrete less water, which assists in regulating the amount of water in the body. Vasopressin is effective because it replaces the antidiuretic hormone (ADH) that is absent in people who have diabetes insipidus and by improving the function of ADH in cases where it is not functioning adequately.

As a Natural Antioxidant 

Natural antioxidants like Beta-alanine and L-histidine are the two amino acids that go into producing the powerful antioxidant known as carnosine. It is a two-peptide compound found in various tissues and organs in the body, such as muscles, brain tissue, and red blood cells, among other places.

Carnosine3 is an amino acid that has shown promise as a potential treatment for many diseases and conditions, including Alzheimer’s disease, brain ischemia, autism, Down syndrome, Parkinson’s disease, and epilepsy. One of the most promising applications for this substance is preventing cataracts from developing in the eyes.

Antimicrobial Effects 

Defensins4 are short chains of amino acids that have a wide range of antimicrobial activity and are an important part of the immune response in the body. Synthetic versions of these molecules are being looked at as possible treatments for several health problems.

In particular, these molecules are being looked at as possible treatments for hepatitis C, pneumonia, HIV, and some bacterial infections. Antimicrobial peptides can be administered topically, orally, or via intravenous (IV) injections.

Iron Absorption 

Hepcidin is a peptide hormone that may help control how much iron the body takes from food. It’s also used for diagnostic purposes. Measuring how much hepcidin is in your body can help determine if you have anemia since low levels show that your body isn’t absorbing enough iron.

Treatment of Inflammatory Bowel Disease 

A peptide known as Chromofungin can potentially be effective in treating inflammatory bowel disease (IBD). It works by altering the production of compounds that contribute to inflammation in the intestine. Based on growing research,5 it may make symptoms of IBD less severe.

What are the Health Benefits of Peptides? 

Even when taken in supplement form, peptides offer many advantages to one’s health. Peptides have been shown to support and improve various bodily functions and processes, including immune system health, muscle growth, sexual health, weight loss, nutrient absorption, and many others.

Peptides have been the subject of research to determine whether or not they can assist athletes in increasing their muscle mass and strength, as well as their overall performance. They have also been investigated for their potential to boost libido and improve sexual health, in addition to providing treatment for erectile dysfunction.

Let’s take a closer look at some of the most well-studied peptides.


A hormone that may help increase the body’s growth hormone production and releases growth hormone. It is commonly used to potentially treat a lack of growth hormone and has improved one’s energy levels, muscle mass, and overall health.


A copper-binding peptide that helps boost collagen production in the skin, reducing wrinkles and improving skin elasticity. It is often used as a potential anti-aging treatment and can help improve the skin’s overall appearance.


PT-141 acts on the nervous system via the activation of neurons in the hypothalamus. It might help treat erectile dysfunction in men and hypoactive sexual desire in women.

What is Peptide Therapy?

Peptide therapy is a type of treatment that involves using peptides to promote health and well-being. Even though getting peptides from food is one option, peptide therapy injections are the best way to get the benefits of synthetic peptides or natural peptides that need higher doses faster.

Injected intramuscularly, this treatment delivers peptides in a form ready to be used immediately. Because it doesn’t have to go through the digestive system, it is 100% bioavailable, ensuring your body receives the maximum peptide therapy benefits.

How do I Know which Peptide might be Right for Me?

Choosing the right peptide for your needs can be a daunting task. With so many different peptides available, it can be difficult to know which fits you best. Talking to a licensed and trained healthcare professional is the best way to determine which choice is best for you.

When consulting with a healthcare professional, it is important, to be honest about your health history and any medications you are currently taking. Some peptides may not be safe for certain individuals due to preexisting conditions or medications.

The Benefits of At-home Peptide Therapy

In the past, peptide therapy had to be done in a doctor’s office or medical clinic. Now, with at-home peptide therapy, patients can get the benefits of peptides from the comfort of their own homes. Here are some of the reasons why clients are making the switch.

Ease of Use

Clients no longer have to be placed on hold just to come and wait in a sitting room for hours before treatment. At-home services allow you to schedule a consultation at a time that works best for you online or over the phone. Your peptide injections will be mailed directly to your door so you don’t have to worry about visiting your local pharmacy.

No Need to Commute

With at-home peptide therapy, patients no longer have to worry about the time and expense of commuting to a medical office for a consultation or ongoing appointments. This makes peptide therapy more accessible to those who live in rural or remote areas, and it can also save patients money on transportation costs. This is a major benefit for clients with small children or mobility considerations.

Range of Peptides to Pick from

At-home peptide therapy offers a wide range of peptides to choose from, making it easier for patients to find the right peptide for their specific needs.

Peptide treatments include:


Peptides may be used to improve athletic performance, improve sexual health, possibly treat osteoarthritis and other musculoskeletal conditions, and do a lot more. In-home treatments can help patients achieve their health goals without needing to commute to or from a clinic or fill prescriptions at a pharmacy.

At-home peptide therapy is increasingly becoming the combination of choice for many people who are looking for a convenient, effective way to prioritize their health and wellness.
