What are Peptides?

Peptides are small molecules composed of 2-50 amino acids, forming a peptide chain connected consecutively.

There are two types of peptides: endogenous and exogenous. What are those?

Endogenous substances are those naturally produced within our bodies and synthesized in diverse cells and organs. They act as messengers facilitating cell-to-cell communication and regulating essential functions, including potential wound healing, immune response, emotional responses, and digestion.

Exogenous are those taken from dietary sources or manufactured synthetically for supplementation or peptide supplements.

The order of the amino acid building blocks gives each peptide a unique shape and function. It's incredible how simply rearranging the sequence can create a peptide that does something different!

Studying these tiny but powerful molecules helps scientists understand how our bodies work at the smallest levels. They are also being explored as potential medicines and treatments for various conditions.

Peptides vs. Proteins

Peptides and proteins are both made up of the same basic building blocks, amino acids. However, their main difference is their size.

Peptides are smaller molecules consisting of short chains of amino acids linked together. Typically, they contain between 2 and 50 amino acid units.

On the other hand, proteins are much larger molecules made up of long chains of amino acids, usually 50 or more amino acids linked together in a specific sequence.

Peptides are like very short strings or necklaces. Because of their smaller size, peptides can more easily travel through the body and interact with cells and other molecules. They often act as messengers, telling cells what to do.

Proteins are more like long, complicated ropes or chains, with more complex 3D structures that allow them to perform various functions, such as catalyzing chemical reactions, transporting molecules, providing structural support, and more.

Another difference is that our bodies can produce peptides, but most proteins must be obtained from our food since they are too large for our cells to synthesize.

Benefits of Peptides

Medicines

  • Many are used to potentially treat various conditions like diabetes, hormone imbalances, cancer, HIV/AIDS, pain management, and transplant rejection.

Vaccines

  • Peptide-based vaccines work by mimicking proteins found in germs that cause diseases. This allows the body to develop immunity safely.
  • These vaccines are used against certain cancers by triggering the immune system to attack tumor cells.

Potential Dietary Supplements

  • Collagen peptide might help your skin stay young and healthy as you get older.
  • They might also help heal cuts and scrapes faster and make new skin cells.
  • They may also aid wound healing, skin regeneration, and the production of extracellular matrix proteins.
  • Antimicrobial peptide supplements could potentially promote wound healing while protecting against infections.

Cosmetics

  • Some face creams and lotions contain these powders, which might help with wrinkles, dryness, and tightness by boosting collagen production (a unique building block for skin).
  • It might also be used to help hair grow thicker and fuller.

Other Uses

  • These might also help keep your bones strong and dense.
  • Some peptides might even help raise your testosterone levels, which can be helpful for some.
  • Some people might use peptides made of creatine and collagen to build muscle and help it recover after exercise.

List of Peptides and What They Do

Nasal Sprays

It is a way to deliver specific peptides directly into the body through the nose. The spray contains peptides in liquid or powder form that can be easily absorbed through the nasal passages.

These allow peptides to quickly enter the bloodstream and reach the brain and other areas, bypassing the normal digestive process. This makes peptide nasal sprays useful for delivering peptides that are unstable in the stomach or don't absorb well when taken orally.

Peptide Vials

Peptide vials are small glass containers designed to store and dispense specific peptides in either powder or liquid form. They typically feature rubber stoppers, enabling the withdrawal of peptides using a syringe or mixing them with other liquids.

Numerous research laboratories and compounding pharmacies provide peptides in sterile, sealed vials to guarantee their purity, stability, and accurate dosing until they are utilized or reconstituted.

Every vial is labeled with the specific peptide type it contains, along with its quantity and concentration and important details like expiration dates and storage instructions.

Using a vial peptide, the rubber stopper is sanitized, and the desired amount is extracted with a syringe and needle under sterile conditions. The peptide can then be injected, mixed into a solution for subcutaneous injection, or added to another liquid formulation.

Frequently Asked Questions

Are peptides safe?

While peptide treatment is usually considered safe when used under medical care, it's essential to be aware of any possible adverse effects, mainly if you use peptide therapy without proper medical supervision. Although the majority of healthy participants are unlikely to experience significant issues caution is urged, particularly for those who have pre-existing medical disorders.

It may cause allergic reactions, such as hives, edema, or trouble breathing. There may also be cardiovascular problems like palpitations and elevated blood pressure. It is not unusual to experience digestive issues like nausea, vomiting, and diarrhea. There have also been reports of cognitive problems such as headaches, tiredness, and dizziness.

What should I consider before buying peptides?

Before beginning peptide usage, consult with a qualified medical professional since they can significantly impact hormones. Be careful when buying these supplements. Stick to stores you trust, like pharmacies or reputable online sellers. Also, check if the particular supplement is allowed for sale in your area.

Think about why you want to take this. Different ones do different things. Some potentially help in building muscle, some might help with weight loss, and others may potentially target wrinkles. There can be downsides, too, so research the risks of the specific compound you're considering. See if it might clash with any meds you take or if it's safe with your health conditions.

Learn the proper way to use it. Find out the right amount. Have a plan for testing relevant biomarkers and monitoring your response to the peptide's intended and unintended effects.
