A Primer on Peptides: What They Are and Why to Take Them

What are Peptides?

Proteins are long chains of amino acids that contain all the building blocks needed to build living cells. Proteins have many functions in our bodies, but they play a special role in the human brain. Our brains need proteins to function properly; without them, we would not be able to think clearly or move effectively. There are two kinds of proteins: structural (which make up the bulk) and functional (used to build structures). Structural proteins are essential for normal brain function. Functional proteins help us perform various tasks such as building new neurons, strengthening nerve fibers, regulating blood sugar levels, controlling inflammation, and much more.

How do Peptides Work?

Peptides work by binding to specific receptors found on cell membranes called GPCRs. These receptors allow other molecules into cells. For example, hormones like insulin and glucagon stimulate the production of glucose from food. Glucose enters the cells where it is used to fuel energy-rich activities such as maintaining the heart’s pumping action, making red blood cells, and producing oxygen. Insulin binds to a receptor called GLUT4 which allows glucose into cells. When there is too little glucose in the bloodstream, your pancreas secretes insulin to bring back some of this sugar from other tissues.

What do Peptides do?

Most of the time, they facilitate things like helping to build more muscle mass or improve short-term memory. However, they can also be used for more serious ailments such as weight loss or even curing opioid addiction. In most cases, the body doesn’t always produce enough functional proteins to overcome ailments and diseases. That’s where synthetic peptides can be injected into the body to give it a push in the right direction.

What is the Best Way to Ingest them?

You can consume peptides in a variety of forms, all of which will be dependent upon the specific peptide in question. Most people prefer capsules or tablets; other individuals may choose to inject a solution of peptides subcutaneously (just under the skin) or even intravenously (directly into the bloodstream).

What are the Different Types?

Peptides can be very beneficial to your body. They help regulate hormones, build muscle mass, improve memory, increase focus, and much more. There are three main types of peptides: diet, somatostatin, and neurotransmitters.


There are many types of dietary peptides. These are used by the body to help keep you in good health. Some of these include:

1. Ghrelin: This peptide tells the brain that the stomach is empty and som Peptides should be released.

It is used to prevent nausea and vomiting.

2. Glucagon like peptide-1 (GLP-1): This peptide slows down the emptying of the stomach, which helps increase the sensation of fullness.

3. Cholecystokinin (CCK): This peptide helps the gall bladder and pancreas release their contents.

It also causes the intestines to relax, which allows food to move through the body more quickly.

4. Gastric Inhibitory Peptide (GIP): This slows down the emptying of the stomach, like GLP-1 and CCK.

5. Pancreatic Peptide (PP): This is another peptide that slows down stomach emptying.

This type of peptide has several medical uses. It is used to treat a condition called acromegaly, which causes the body to produce too much growth hormone. It can also be used to treat a tumor called a glucagonoma, which releases too much glucagon.


Neurotransmitters are chemicals that are used by the brain to send signals from one neuron to another. They can also be released by neurons in the autonomic nervous system that controls organs like the heart, lungs, and digestive system. Dopamine is a neurotransmitter that is often used to treat Parkinson’s disease. It can also be used to treat low blood pressure and reduce the pain caused by cancer.

How Long Before I See Results?

This is going to vary depending upon what you are using the peptides for. Some peptides can have an effect almost immediately, while others may take up to a month before you notice a change. Most bodybuilding supplements, however, will start working within a week. You may experience muscle aches or even an upset stomach during this time. These side effects should go away within a couple of days. If they last longer or become severe, stop using the peptide and seek medical attention.

What are Potential Side Effects?

Side effects with these types of supplements are usually mild. They can include nausea, cramping, headaches, or diarrhea. These symptoms usually go away after your body gets used to the supplement. If the problem persists or gets worse, you need to consult with your physician immediately.

What are Some Potential Risks?

Using any type of supplement can be risky. The main risks with peptides are they can cause your body to produce too much or too little of a certain hormone, which could have dire consequences. There is also some concern that the release of hormones from a pill can’t be controlled as well as they can by your body, which could lead to unknown side effects.

What If I Have A Pre-Existing Condition?

If you have a pre-existing condition such as high blood pressure, diabetes, cancer, or heart disease, you should not take bodybuilding supplements without the supervision of a physician. The wrong supplement could have serious consequences for people with these types of conditions.

As peptides can produce dramatic effects on your body, it is important to consult with a physician before using them. Also, it is a good idea to start with a small dosage and work your way up. This allows your body to get used to the supplement and reduces the side effects.

What If I Want To Lose Weight?

If you want to use peptides for weight loss, you will need to talk to your doctor as well. Certain peptides can be used for this purpose, but it is important that you take the right one and use the right dosage. A doctor can help you determine what you need.

It is a good idea to also start an exercise program and diet when using peptides for weight loss. The right supplement will help you lose weight, but you still have to do your part by eating right and exercising.

What If I Want To Build Muscle?

Bodybuilding supplements like peptides are not going to build muscle for you. You still have to exercise in order to see results. However, the right supplement will help your training and muscle recovery so that you can work out harder and obtain the results you are looking for. A doctor can help you determine which supplement is best for you and how much to take.

What If I Want To Improve My Athletic Performance?

Peptides can also improve your athletic abilities by allowing you to train longer and harder, as well as speeding up the recovery process so you can train more frequently. A doctor can help you choose the right product as well as determine the dosage that will work best for you and your needs.

What If I Just Want To Look Good?

Bodybuilding supplements like peptides can certainly improve your appearance by helping you gain or lose weight as needed, developing more muscle, and improving your complexion. A doctor can determine what product is best for your goals and help you decide on the right dosage.

And as always, it is a good idea to exercise and follow a healthy diet. Bodybuilding supplements will not do anything for you if you’re not eating right and exercising. However, they can certainly give you the edge you need to maximize your potential.

Can I Buy These Products At Gnc Or Other Health Stores?

Peptides are available for purchase at some health food stores, but they cannot be sold as an immediate drug.
