WHAT ARE PEPTIDES
Peptides are naturally occurring biological molecules that are found in all living organisms. They play a major role in all manner of biological activity in the body. Like proteins, peptides are formed naturally from a sequence of the genetic code, ie DNA. There are 20 aboundant and naturally-occurring amino acids. They, similar to words can be combined into large variety of different molecules. When a molecule consists of 2-50 amino acids it is called a peptide, whereas a larger chain of > 50 amino acids typically referred to as a protein.
In the body, peptides are found in every cell and tissue and perform a wide range of important and essential functions. Maintenance of appropriate concentration and activity levels of peptides is necessary to maintain health and acheive balance.
HOW DO PEPTIDES WORK
How a peptide functions is largely in part due to the types of amino acids involved and they way in which they are put together. Peptides may often act as hormones and are then thought of as biologic messengers carrying information from one tissue through the blood to another. There are two common classes of peptide hormones and steroid hormones. Peptide hormones are produced in glands, and a number of other tissues including the brain, stomach, and intestine. Examples of peptide hormones are those involved in blood glucose regulation, including insulin, glucagon-like-peptide 1 (GLP-1) and glucagon, and those regulating appetite, including ghrelin. A peptide needs to bind to a receptor specific for that peptide located in or on the membrane of relevant cells, enter the cell and activate a recepter to produce it's full effect. This series of biological activity occurs througout the body.
PEPTIDES & HORMONES
There are several peptides on the market aimed at boosting althetic performance, promoting longevity of life and optimzing overall health. Many of which have been used "off-label" with a great deal of benefit. The use whether it be for anti-aging vs wellness vs atheltic performance depends largely on dosing and/or the combination of certain peptides. This is one reason why certain peptides are recommended for different uses. Here is a list of peptides that may have athletic performance optimizing capabilities.
ARE PEPTIDES SAFE
They are safe to use but educated prescribing is vital. Like any medication or treatment, peptides can have risks, side effects and contradictions. For example, some may be avoided if the patient has a history of melanoma. For this reason, it’s important to look for a provider who has knowledge, experience and includes a comprehensive medical history before prescribing.
