Peptides are short chains of amino acids present in all living creatures. They are easier for the body to absorb than proteins because they are smaller and enter the bloodstream quickly. The body naturally produces peptides but can decline in number and quality as we age. This is why peptide treatments can provide a variety of health benefits. 

Types of peptides

Peptides are characterized in three main ways – how many amino acids make up the chain, whether the source is animal or plant, and what functions they have in the body. Their effects on the body depend on the sequence of amino acids they contain. 


Dipeptides are created by joining two amino acids together with a peptide bond. They function as antioxidants in the body and help to maintain the pH of cells. Carnosine is an example of a dipeptide that’s present in many areas of the human body. Research suggests it may be beneficial in treating many illnesses. 


Tripeptides are created by joining three amino acids together with peptide bonds. Glutathione is a tripeptide that acts as an antioxidant and helps the immune system to function properly. 


Oligopeptides are created by bonding of more than two and less than 20 amino acids. They are often used in skincare because they are absorbed at the cellular level and stimulate collagen production, giving the skin a more youthful appearance. Certain types of oligopeptides send a signal to the skin to repair itself, so they help to trigger healing and reduce inflammation. 


Polypeptides consist of more than ten amino acids but less than 100. Glucagon is an example of a polypeptide. It is a hormone that triggers glycogen to convert back into glucose so that your body can use it for energy.

Effect of peptides on the body

Some of the benefits of peptide therapy can include but are not limited to the following:

  • Accelerate healing processes 
  • Decrease joint and muscle pain 
  • Enhance memory
  • Boost hormone levels 
  • Help with sexual dysfunction
  • Improve sleep quality 
  • Lower blood pressure
  • Reduce signs of aging

Stimulates the release of aldosterone

Angiotensin is a peptide endocrine hormone that stimulates the release of aldosterone. Aldosterone is a steroid hormone produced in the adrenal gland. It manages the levels of sodium and potassium in the body and impacts blood volume. 

Regulates blood pressure

When the arteries stiffen and plaque deposits make vessel walls narrower, it’s harder for blood to flow, and the risks of high blood pressure increase. Some research indicates that the peptide glycine promotes heart health as it reduces blood pressure and protects against arterial damage. It also improves the body’s ability to use nitric oxide, which increases blood flow and lowers blood pressure

Plays a pivotal role in the milk ejection reflex

Oxytocin is a peptide hormone that consists of nine amino acids. It stimulates uterine contractions during childbirth and is necessary for the milk-ejection reflex. In addition, it triggers the flow of milk from the mammary glands into the mouth of the baby. 

Ways of taking peptides

The number of peptides in the body may decline due to aging. This is why peptide therapy can make a difference. Peptides are typically administered directly into the bloodstream through injections, but topical sprays, creams and oral forms of peptides are also available. Peptides can assist in promoting your overall health and wellness with minimal to no side effects as they occur naturally in the body and are well tolerated. 

Peptide injections

Peptides made in a lab can mimic some of those found in the body. Drip Hydration, LeifeTein and Elementer offer peptide therapy in NYC. This consists of at-home self-administered peptide injections, which offer a wide variety of benefits. There are different types of peptides that can target different areas. Some can help build lean muscle mass and improve athletic performance. Others can modulate the sleep/wake cycle. Then there are those that exhibit anti-aging properties by stimulating collagen production.  

You will first consult online with a licensed medical provider to determine if you are a suitable candidate for peptide therapy. You will receive peptide injectables in your home and the materials necessary to self-administer your peptide injections. Treatments can provide health benefits such as immune health, muscle and joint recovery, improved sleep, and longevity.

Oral administration

Taking peptides orally means they go through the digestive process and not directly into the bloodstream. This means they can take longer to work. Peptides are sold in various forms for oral administration, such as pills, powders, and shakes. 


Peptides essentially tell cells to perform tasks. They occur naturally in the body, so they are both safe and effective to take. You can experience a variety of benefits to your overall health and well-being with peptide therapy.
