Peptides for Muscle Growth: What Can You Use in 2023?

Let’s talk about peptides for muscle growth today.

As people get more passionate about being fit and looking fit, bodybuilders and individuals have found various ways to help people achieve their desired body in the shortest and healthiest ways possible.

Bodybuilders have been using peptides for a while now. It has now become one of the widely used performance-enhancing substances. One of the reasons it has been widely accepted is that it is considered a more natural substance than other alternatives like anabolic steroids. 

This article reviews peptides for muscle growth and some of the best peptides you can use.

What Are Peptides?

Peptides are short chains of protein comprising amino acids. They are naturally found in the body and are useful in various biochemical processes. This includes anti-aging, hormone production, muscle building, and anti-inflammation. The biochemical structure of peptides is similar to certain hormones and chemicals in the body.

In the fitness world, peptides are increasingly used to build muscles, increase activity levels, improve athletic performance, and burn fat. Peptides can be derived from animal or plant sources like meat, eggs, milk, greens, and beans. These peptides are similar to what we find in the body.

The rate at which the body produces peptides gradually starts reducing with advancing age. As a result, companies can now produce their exogenous peptides by combining amino acids or isolating and concentrating these peptides into packaged products. 

What Are the Best Peptides for Muscle Growth?

There are various types of peptides based on the arrangement, number, and types of amino acids present in the peptide. These peptides work through various pathways to achieve similar results but at different potencies and with different effects.

Peptides similar to growth hormone (growth hormone secretagogues – GHS) are the most important peptides used to promote muscle growth as they stimulate the secretion of human growth hormone (HGH). This hormone is the one responsible for improved muscle growth and body fat reduction.

Here are some of the best of the many types of peptides for muscle growth.

Growth Hormone Releasing Peptide (GHRP)

This is the leading product when it comes to using peptides for muscle growth. There are still various types of GHRP. However, there have been claims that GHRP-6 is the best of the growth hormone-releasing peptides.

GHRP stimulates the release of ghrelin, one of the digestive substances that regulate appetite. It is used by bodybuilders and fitness enthusiasts who find it challenging to meet us with their high-calorie dietary needs. After about 30 minutes of taking GHRP, you should start feeling starved.

Various scientific research works have found that it helps people gain their desired lean body mass. In addition, it also promotes the shedding of body fat mass.

How to use GHRP:

The recommended dosage is calculated based on the user’s body weight. 

1 microgram/kg per day is the recommended daily dosage. It should be injected one time before breakfast and one just before going to bed. 

Effects of using GHPR:

  • Stimulates appetite
  • Improves lean body mass
  • Promotes energy levels giving room for stricter and longer workout sessions
  • It improves your quality of sleep, although it does not necessarily increase the duration. 
  • It promotes recovery from injuries and fatigue from intense workouts.


Ipamorelin is one of the most recent advancements in this industry. Unfortunately, the knowledge of the drug is not still as widespread as GHRP. Still, it is increasingly being used by bodybuilders and fitness enthusiasts who do not have a problem meeting their daily caloric requirements.

GHRP is not the best option for this set of people because it unnecessarily stimulates their appetite. And this is where ipamorelin comes into the scene. 

Ipamorelin is a form of growth hormone that mimics ghrelin without having to stimulate appetite to increase its release. Ipamorelin also increases the production of growth hormones from the anterior part of the pituitary gland. 

How to use Ipamorelin:

In the morning, start with 100 mcg. Then, you can gradually raise it to 200 mcg each day after that. 

When paired with 100 mcg GRF-MOD 1-29, it has been demonstrated to be especially useful. 

A minimum of an 8-week cycle is recommended, with a maximum of a 12-week cycle. 

These are the effects of ipamorelin:

  • Reduces body fat
  • Increased lean muscle growth
  • Enhances workout recovery
  • Has anti-aging properties as it improves skin and nail appearance
  • Does not have much influence on the level of cortisol production or release in the body.


Hexarelin is also known as examorelin. It is another powerful GHRP that stimulates the production and release of growth hormones in the body. This causes a more noticeable, leaner muscular mass by stimulating cell regeneration within the muscles.

Various research works have shown that while taking Hexarelin, some bone markers increase, implying that it helps build bone density. This potentially lowers the risk of developing osteoporosis and/or fractures later in life.

Hexarelin is usually injected as 100 mcg at the same time of the day every day. 

It is a therapy that takes 30 days, after which you should rest for one or two weeks to achieve the best result. 

The effects of hexarelin include:

  • Increases muscle growths
  • Promotes strength gains
  • Reduces body fat
  • Stimulates performance
  • Leads to more noticeable muscle tone
  • Promotes the body’s healing process.

Follistatin 344

Follistatin has been increasingly common among bodybuilders and fitness enthusiasts in the last couple of years. However, the reasons behind this are far-fetched.

Follistatin increases the process of cell growth in all parts of the body. This, in turn, increases muscular tissue in reaction to any form of injury or stress. Various studies have pointed this out.

A substance called myostatin has been found to restrict how quickly and how much muscle one can gain muscle mass. One added functionality of follistatin is that it also functions as a myostatin inhibitor.

Consequently, it has been found to speed up muscle growth because myostatin no longer restricts how quickly one can build their muscle. This is one of the most important things about follistatin in assisting bodybuilders to acquire muscle faster than average.

100 mcg of follistatin is required once daily over ten days to a month. 

The effects of follistatin include:

  • Stimulates significant muscle growth within a short amount of time
  • Cuts down the sizes of the cells that store fat (adipocytes), thereby reducing the build-up of fat in the body.
  • Improves fertility
  • Reduces muscle loss
  • Rapidly increases the lean muscle mass


This is one of the HGH-releasing peptides. It stimulated the breakdown of triglycerides and fats. It is considered a good place to start for people hoping to reduce their abdominal fat.

Although it is normally produced in the body, exogenous use stimulates the pituitary gland to release GHRH. Tesamorelin also stimulates fat breakdown (lipolysis), thus enhancing lean muscle growth.

CJC 1295

This is now getting increasingly used alongside ipamorelin.

This is because they have a synergistic effect that allows both substances to work more effectively together than independently. In addition, CJC 1295 reduces recovery time after intense workouts by stimulating plasma growth levels.

Other forms of peptides used for muscle growth include BPC -157 and IGF-1.

Wrapping up

Peptides are becoming increasingly accepted for bodybuilding as it offers a closely natural way of getting one’s dream body. There are various types of peptides for muscle growth. But they mostly work to stimulate the release of growth hormone-releasing hormone.
