2) Best Growth Hormone Peptide Antagonist – Sermorelin

Sermorelin acetate is the acetate salt of an amidated synthetic 29-amino acid peptide (GRF 1-29 NH 2 ) that corresponds to the amino-terminal segment of the naturally occurring human growth hormone-releasing hormone (GHRH or GRF) consisting of 44 amino acid residues (11).

It mimics the action of the naturally occurring growth hormone-releasing hormone (GHRH).

The subsequent binding of sermorelin to the growth hormone-releasing hormone receptors (GHRHr) stimulates somatotrophic cells to secrete growth hormone (GH).

Higher growth hormone (GH) levels stimulate the production of new muscle fibers at a faster rate. This leads to the bulking of muscles.

Sermorelin users have also reported experiencing greater muscle gain after intense workout sessions.

Sermorelin Summary

#2) Best Growth Hormone Peptide Antagonist: Sermorelin

Sermorelin, an acetate salt comprising 29 amino acids, stands as a synthetic peptide designed to emulate the natural action of growth hormone-releasing hormone (GHRH).

In contrast to the 44 amino acid residues in naturally occurring GHRH, Sermorelin’s GRF 1-29 NH2 structure targets the growth hormone-releasing hormone receptors (GHRHr) situated in the anterior pituitary gland.

Upon binding to these receptors, Sermorelin prompts an increase in the production and secretion of growth hormone (GH) by somatotroph cells. A pivotal aspect of this process involves the feedback mechanisms that regulate hormonal levels. 

The heightened serum concentration of GH, triggered by Sermorelin, prompts the release of somatostatin or growth hormone inhibiting hormone (GHIH).

GHIH, in turn, initiates a negative feedback loop, preventing further GH secretion by somatotroph cells to maintain hormonal balance. Sermorelin’s unique mechanism ensures the preservation of homeostatic coordination within the hypothalamus-pituitary-somatostatin axis.

Beyond its role in hormonal regulation, Sermorelin contributes to improved sleep-related circadian rhythms by reducing stress hormone production. 

This dual action not only facilitates the release of GH but also supports overall well-being, making Sermorelin a multifaceted peptide with potential benefits for those seeking hormonal balance and enhanced sleep patterns.

Do Peptides Actually Work For Muscle Growth?

Before learning more about different peptides that can be used, it is important to have a thorough understanding of how peptides work at the cellular level to induce muscle growth.

There are multiple categories of peptides that bodybuilders specifically use to trigger muscle growth, such as growth hormone-releasing hormone (GHRH), growth hormone-releasing peptides (GHRPs), and growth hormone secretagogues (GHS).

Although the end goal is the same to induce muscle growth, different peptides follow different pathways.

Our muscle fibers are made up of contractile filaments called actin and myosin, which are responsible for contracting and relaxing muscles for mobility (1).

Peptides like TB-500 make our body more responsive to actin by increasing its reception. This increases the growth and proliferation of muscle cells (2).

Other peptides, such as Ipamorelin, Sermorelin, Hexarelin, and CJC-1295, stimulate the natural release of growth hormone (GH) from the anterior pituitary gland (3,4).

Growth hormone (GH) can act on myocytes and trigger the growth of new muscle fibers.

Some peptides inhibit the release of somatostatin, also known as growth hormone-inhibiting hormone (GHIH) (5).

Thus, growth hormone (GH) levels are always kept at the optimal limit to achieve considerable growth of muscles.

Peptides also stimulate the release of insulin-like growth factor-1 (IGF-1) from the liver. IGF-1 causes the production of muscle proteins which leads to increased muscle growth (6).

Peptides like follistatin 344 inhibit a naturally occurring regulator of muscle growth called myostatin (7). Myostatin acts to limit muscle growth beyond a certain point.

Follistatin 344 inhibits myostatin which leads to excessive growth of muscle fibers, leading to amplified muscle growth (7).

Additionally, these peptides also promote angiogenesis, which is the formation of new blood vessels around the muscle region (8).

This ensures an adequate supply of oxygen, nutrients, hormones, and growth factors to the myocytes for optimal muscle growth.

How To Take Peptides

Best Peptides for Muscle Growth

Once you have decided on the specific peptide you will use, you need to look for its available forms.

Some peptides can be injected, taken orally, or used as patches, whereas others can only be used in injectable form.

Many studies have shown that peptide hormonal therapies are most effective when injected and as such most vendors only produce peptides in this form.

Ipamorelin 🌟🔬Safe and effective GHRP with fewer side effects. Can be combined with CJC-1295 (without DAC) for synergistic effects.
IGF-1 LR3 or IGF-1 DES 🏋️‍♂️💉🛠️Direct role in muscle growth. LR3 has a longer half-life, while DES is a shorter, more potent version. Use post-workout for muscle growth and repair.
BPC-157 and TB-500 🩹🔄🚑Not directly related to muscle growth but included for injury recovery and healing properties.

The efficacy and safety of peptides largely depend on individual physiology, goals, and how they’re administered.

When it comes to muscle growth, several peptides have garnered attention for their potential effects on increasing muscle mass and strength.

It’s always crucial to consult with a medical professional before starting any peptide regimen. That said, here’s a popular peptide stack for muscle growth:

CJC-1295 DAC with GHRP-6 or GHRP-2: 

This is a popular combination that maximizes growth hormone release. CJC-1295 DAC is a long-acting growth hormone-releasing hormone (GHRH) analog.

When combined with a growth hormone-releasing peptide (GHRP), like GHRP-6 or GHRP-2, it can lead to significant GH release.


Another GHRP, it’s considered one of the safest and most effective for GH release, with fewer side effects (fewer hunger spikes than GHRP-6 and no cortisol or prolactin spikes). 

It can be combined with CJC-1295 (without DAC) for synergistic effects.

IGF-1 LR3 or IGF-1 DES: 

IGF-1 (Insulin-like Growth Factor-1) plays a direct role in muscle growth. LR3 has a longer half-life, and DES is a shorter, more potent version. 

They can be used post-workout to help with muscle growth and repair.

BPC-157 and TB-500: 

While they aren’t directly related to muscle growth, these peptides are often included in muscle-building stacks due to their injury recovery and healing properties.

Remember, the combination and dosage will depend on individual goals and needs.

Additionally, it’s vital to be aware of potential side effects, both of individual peptides and when they’re combined. The legal status of peptides can also vary by country or region.

It’s essential to ensure you are complying with local regulations and using peptides responsibly. Always consult with a medical professional before starting any peptide regimen.

Are Peptides Safe For Bodybuilding/Muscle Growth?

As all peptides work in a specific way, each of them needs to undergo human-based clinical trials to prove their safety.

Since not many peptides have completed human-based clinical trials, the WADA and FDA haven’t legalized the usage of many peptides available.

But results from several animal-based clinical trials suggest that peptides are generally safe. They have tested positive to bring muscle growth in the subjects involved in the research.

With a few side effects here and there, such as headache, redness at the injection site, and appetite changes, no severe side effects have been reported, which is why many bodybuilders are often inclined to use peptides over steroids or SARMs to catalyze their journey.

Which is the Best Peptide Stack For Muscle Growth?

A lot of bodybuilders stack peptides to experience optimum synergistic benefits. Amongst the stacked peptides, the most common is the use of CJC-1295 and ipamorelin.

Ipamorelin, also a growth hormone secretagogue (GHS), comprises 5 amino acids. It binds with receptors located peripherally, such as on myocytes and adipocytes.

As both the peptides work towards increasing the serum levels of growth hormone (GH), they can be used well together to build muscle significantly, lose body fat, and cause a boost in overall energy levels.

Since both the peptides have different half-lives, these can work together to supplement each other’s effects.

Take-Home Message

After studying the working of peptides thoroughly, I believe that peptides can catalyze the process of muscle building and bulking.

Some of the peptides like follistatin 344 work organically and directly to bring muscle growth.

In contrast, others such as sermorelin and hexarelin follow an indirect route to build muscles.

Nonetheless, if you follow dedicated workout sessions and a strict diet, you should use peptides to achieve results faster.


Which peptide builds the most muscle?

While various peptides play a role in muscle growth, the peptide that’s often considered the most effective for building muscle is Hexarelin. Its potent action as a growth hormone-releasing hormone (GHRH) receptor agonist makes it a top choice for those seeking maximum muscle gains.

Which peptide do bodybuilders use to increase lean muscle mass?

Bodybuilders commonly turn to Ipamorelin, a growth hormone-releasing hormone (GHRH) analog, to increase their lean muscle mass. It offers a safe and legal option to enhance muscle growth and achieve a more sculpted physique without resorting to anabolic steroids or other prohibited substances.

How do growth hormone-releasing hormones affect muscle growth?

Peptides such as Hexarelin and Ipamorelin are popular choices among bodybuilders and fitness enthusiasts, as they effectively stimulate the release of growth hormone, leading to increased lean muscle mass.
