Peptide Introduction

What Are Peptides?

Peptides are known as ‘little proteins’, because they are compounds where two or more amino acids, which are the basic building blocks for tissues, organs, muscles, skin and hair, have joined together. As a general guideline, a peptide will contain 50 or fewer amino acids, though this is not a strict definition. Larger chains of 50 or more amino acids are proteins.

There are 20 naturally-occurring amino acids, though only 10 are produced by the body, the other 10 must be supplied via the food we eat or through supplementation. Just like letters create a range of words, amino acids can be combined to create a range of different of peptides and proteins.

In the human body, peptides are found in virtually every cell of the body and perform a wide range of essential functions. Maintenance of appropriate concentration and activity levels of peptides is necessary to achieve homeostasis and maintain health.

As your body ages, hormone, enzyme ,amino acids and peptide production starts decline. This is one reason why the body starts to become weaker as we get older, why we gain fat instead of muscle, and why our skin starts to sag and all the good things we hold dear are slowly exchanged for things associated with aging that no one realistically wants,

Synthetic peptides have been designed to stimulate specific receptors for HGH, hormone and enzymes so that you can tailor your results and continue to get results as you age.

To begin with, we need to understand how our bodies function. At the base of our brain rests a small gland called the Pituitary Gland. Despite the fact that the Pituitary Gland is small, it is the control unit to other hormonal glands, for example, Adrenals and Thyroid, which are vital to a vast part of controlling your body and general wellbeing.

In order to keep a sustainable balance in your body, the Pituitary Gland sends signals (hormones) into the circulatory system to the other organs and glands in your body to control or create their own hormones as needed.

What Do Peptides Do?

Peptides play a variety of roles throughout the body.

Some peptides act like neurotransmitters and have more of a nootropic affect.  While others will change the way your body reacts to diet and physical exercise. We are looking at the peptides that contribute to your body’s natural production of Human Growth Hormone (HGH).

HGH is naturally produced in the body and affects nearly every part of the body from muscles, to bone, nervous system, skin and even hair. It is often considered the ‘Fountain of Youth’ hormone because when we reach our 30’s our natural HGH production starts to declines.

HGH benefits include;

  • Faster Recovery and repair
  • Increased Lean Muscle Mass and muscle tone
  • Reduced body fat levels
  • increased Injury Recovery
  • Stronger bone mass
  • improves skin and hair density and appearance
  • Improved sleep and wellbeing
  • Elevated energy and strength levels
  • Helps to optimise, maintain, build and repair healthy tissue in the brain and other organs
  • Helps to reduce the onset of aging processes in the body

HGH is produced in the pituitary gland, deep in the brain, and it circulates through the blood to the liver, where it stimulates production of Insulin-like Growth Factor-1 (IGF-1).-1 is important in the development of lean muscle and is a key factor in the negative feedback loop that causes decreased natural production and release of HGH from the pituitary when the hypothalamus is made aware of the level of HGH in the body.

This means that when there are low levels of HGH, the hypothalamus will release stimulators of HGH called Growth Hormone Releasing Hormones (GHRHs) and when the levels are high it will work to lower production.

When your body isn’t absorbing or producing enough amino acids, it can’t produce enough peptides. And when it can’t produce enough peptides, your production of HGH will be lowered.

This is why synthetic peptides are becoming a natural draw for many athletes.

Benefits of peptides

Peptides were primarily created to treat HGH deficiency, though they offer 3 main benefits to strength and endurance athletes, bodybuilders and powerlifters. Firstly, they are designed to increase the production of Testosterone, so they can improve strength and accelerate muscle growth.

Another benefit of peptides is their anti-inflammatory properties, which allows for better recovery from harder workouts and also faster healing after injuries.

The other benefit of peptides is their ability to transport oxygen to the muscles. This make them an attractive option for endurance sports such as swimming, running, and cycling.


Unlike with the likes of other restorative skincare ingredients such as the much lauded retinol and hyaluronic acid, peptides can seem a bit mind boggling and mysterious, and the fact that there are hundreds of them out there doesn’t help.

Proven peptides for skin enhancement are PAL_GHK, GHK-cu Snap8 even though HGH plays an important role in skin health.

Dermatologists at skincare brand DCL sum up the conundrum neatly:

“In the skincare world, peptides are the beauty equivalent of ‘gluten-free’ in the food realm: Everybody looks for it on packaging, but many aren’t sure why it makes a difference. Yet peptides are not simply marketing jargon.”

As skin experts would concur in her clear-cut explanation of what they actually do:

“Peptides are fragments of proteins. On their own, peptides are made up of amino acids. When amino acids are combined in certain formations they create specific peptides, and when peptides are formed in a certain way, they make specific proteins.

“Proteins are the fundamental building blocks of skin. Without peptides, skin doesn’t remain intact and the result is loss of firmness, appearance of wrinkles, texture changes, and skin that doesn’t bounce back as it once did.”

DCL present collagen as a peptide-in-action case study:

“Think of them as air-traffic controllers for your skin. One of our skin’s most important proteins is collagen, which gives our skin its thickness. Collagen breaks down in the skin due to age, environmental factors, UV rays and stress, causing wrinkles to form. The good news is that peptides, when applied topically to the skin, can then send a signal to produce new collagen, leading to the appearance of younger, more supple skin.”

In addition to revving up collagen synthesis, peptides are thought to strengthen other proteins in our skin such as keratin and elastin, and the abundance of different peptides out there work in different ways towards different aims, as our skin expert explains explains:

“Some peptides have demonstrated a remarkable skin-soothing effect, while others can improve the appearance of wrinkles, loss of firmness, and even help to soften the look of expression lines.”

Peptides and Mental Health/ Sleeping disorders

Peptides even have incredible positive effects on many mental health problems and its ability to learn.

Salank the peptide nicknamed “Limitless” with is ability to increase learning

Selank is a small protein produced in Russia to treat anxiety and improve learning. No side effects have been observed. Selank is an anti-anxiety/depression and stress compound that improves learning and increases energy without side effects or the risk of addiction.

DSIP also designed for the same purpose with the added benefit of helping with sleep disorders like insomnia and boosting HGH and hormone levels giving all the benefits HGH.
