Peptides are a growing area in medicine right now and there is much excitement about their function and use. Some peptides have been well known and in use for some time like insulin for diabetes. As I am sure you know, insulin is needed for the body to utilize sugar and its action lowers blood sugar levels. Glucagon is also a well-known peptide, it is sort of the opposite of insulin in that it works to raise glucose in the blood.
At this point, we have discovered an incredible diversity in the effects peptides can have on the body. There are hormone peptides such as CJC 1295, ipamorelin, and tesamorelin that increase growth hormone secretion through the ghrelin and growth hormone receptors. Peptides such as glucagon-like peptide (GLP-1) have found use in treating diabetes by lowering blood sugar. Some peptides promote healing such as BPC-157 and thymosin beta 4. We have used peptides like GHK-Cu to help with anti-aging by reversing damage to the skin and hair loss. There have been some crazy peptides that almost sound like science fiction such as melanotan. This peptide promotes melanin synthesis which allows users to have a nice, dark tan but it also stimulated sexual desire and function. The part of the melanotan peptide responsible for the sexual effects was isolated and is known as bremelanotide or PT-141. This was recently FDA approved to treat Hypoactive Sexual Desire Disorder in women.
This is just scratching the surface of the many types of peptides that are being studied. We will go into several of these that relate to our area of wellness and regenerative medicine on an individual basis in future blog posts. Stay tuned!
