Weightlifting, bodybuilding, and fitness, in general, are all about using what resources you have at your disposal. The most precious of all is time. Peptides have become extremely popular in the fitness community to alter body composition as quickly as possible, whether it is for competitive purposes or more personal goals. Certain peptides and peptide-like substances may circumvent their addition to a bodybuilding diet by hiding in supplements, but most are not allowed for human use unless otherwise directed and approved for any medical or therapeutic consumption.

In this post, we will explore what peptides are, get more specific on the advantages and disadvantages of collagen peptides and their side effects, and ultimately, list the best place for all your peptide needs. Please keep in mind that the direct sale of peptides is for approved research or laboratory use.

What Are Peptides?

Peptides aren't a negative or positive occurrence, they are natural building blocks that occur within the body - meaning they are a type of amino acid (short-chain). Peptides are building blocks of proteins, amino acids, and other peptides. They usually come from animal sources, but those with a vegan or vegetarian preference can also find them in certain natural supplements or even in a diet that is rich in beans, lentils, and other whole grains. 

Peptides are helpful for several reasons within the body; they regulate various actions and feelings throughout every system. They are primarily concerned with the production of hormones, and the structure of your DNA. They are often viewed as a "natural" or " healthier" alternative to anabolic steroids because they do not aim to change or alter your body's properties, but rather to provide a conducive environment for development. The fitness community pays particular attention to peptides that assist in muscle growth, prevention of injury, or any compound that can give them a "shortcut". 

The most popular types of peptides in today's market are GHS (growth hormone secretagogue), and collagen. GHS is handy in boosting the transmission of growth hormones throughout the body. We will discuss further the pros and cons of collagen below.

Pros And Cons Of Collagen Peptides

Collagen is a peptide (sometimes even a protein) that is well known in the skin-care community, and many products contain this addition. It is not just used for skin care but many other muscles, ligaments, and joints found in the body. Collage is a protein that is found within the body that promotes cell turnover, which means that it is directly responsible for creating new cells when the others are old, damaged, injured, or unhealthy. Collagen works best when combined with vitamin C, as it is crucial for the synthesis of new collagen proteins. Here are the pros and cons of collagen peptides:


Skin health. Of course, the most well-known use for collagen is skin health. It not only strengthens the skin by promoting new cell creation and growth, but it also increases elasticity and hydration and helps with acne.

Joints and bones. Certain types of collagen are found in connective tissue, which primarily affects the joints. Collage intake would help the integrity of the cartilages, bringing them back to their "rubbery" nature.

Muscle development. Collagen is found in muscles that surround and support the skeleton, meaning they will increase the mass of your auxiliary muscles that are used often for lifting and pushing.

Cardiovascular enrichment. Collagen helps to support and protect the arterial walls, making them stronger and able to resist moments of higher blood pressure and the effects of LDL cholesterol.

Things to Be Wary of

Collagen has some side effects, which we will list below. Before we get to the adverse reactions, it is important to be cautious of one downside to collagen. Those with food allergies that contain fish, shellfish, and eggs should steer clear, as collagen mimics the protein structure of these foods. Thankfully, these are not food items that comprise a vegan diet.

Orgain Collagen Peptides Side Effects

Side effects include:

  • These collagens contain bovine collagens, which can both cause allergy flare-ups and are not vegan or vegetarian friendly.
  • It can leave a lingering bad taste in your mouth, affecting your appetite.
  • It can irritate the stomach lining and esophagus, causing heartburn, digestive problems, and bowel movement inconsistencies.
  • It can affect hormonal imbalance at first, which may cause some people to have small episodes of panic, anxiety, or restlessness.

What do peptides do for muscle?

Peptides contain amino acids, and they are also the building blocks of certain proteins. Not only does this directly affect the composition of muscle mass, but certain peptides also help in the release of hormones that promote muscle development and bone growth, and repair your tissues and ligaments.

Should peptides be refrigerated?

Since peptides are similar to proteins, they will break down unless they are stored in a cool and dark place. Depending on what form the peptides have been stored in, the label could list something different. Generally, it is safe to do so - however, you should always follow the directions of your provider, professional, or even the label.

Are collagen peptides dairy free?

This question depends on the brand. Collagen peptides themselves are naturally occurring within the body, meaning they are gluten-free, sugar-free, keto, and dairy-free. Certain peptides come from animal sources and may not be vegan friendly. It is always best to check the composition and FAQs before purchasing.
