Best Peptides for Bodybuilding

Peptides are often overlooked because they can be expensve, or because they are better for fat loss. What are the Best Peptides for Bodybuilding?

Peptides! These bad boys increase your Growth Hormone, Testosterone, recovery, and so much more that they are beginning to look a little too good to be true.

The more Human Growth Hormone you have, the better you will be able to recover and perform – that makes sense.

But what about Frag? CJC-1295? Ipamorelin? BPC-157?! There are so many, which are the best peptides for Bodybuilding?!

Relax. I’ve been using these for a while and I have a degree in Chemistry. I have taken the time to learn about these compounds and how they work.

So pinch a bit of fat around that stomach, load up your syringe, and let’s delve into the beautiful world of Peptides.

Key Takeaways

  • There are several Peptides for muscle growth on the market
  • The one that stands above all will always be Human Growth Hormone
  • Peptides are not as good as Steroids for muscle growth
  • You’re better off combining different peptides with one another for the most optimal results

What are the best Peptides for Bodybuilding?

Narrowing down the best peptides for a bodybuilder is quite hard. See, there are several different peptides, all designed to do something different.

For tense and purposes, we are going to focus on those that help with weight gain, weight loss, Growth Hormone secretagogues, and those that have anti aging properties.

This is what most bodybuilders actually use. They will not increase muscle protein synthesis as much as Steroids or SARMs would, but IGF-1 (Insulin Like Growth Factor) is still quite strong.

Increasing the natural production of IGF-1 can lead to some pretty insane results if used correctly.

ADO 9604 Summary

AOD 9604

Losing excessive body weight and getting rid of obesity has just become much easier with the introduction of AOD9604 in the market.

AOD9604 is a synthetic fragment of the human growth hormone (HGH) C-terminus (176-191). This hexadecapeptide has shown remarkable effects on fat metabolism by upregulating lipolysis and inhibiting lipogenesis.

AOD9604 targets fat-rich areas and promotes fat breakdown without disturbing the overall metabolic profile.

AOD9604 was well advocated as an anti-obesity medication in the past as it cuts down fat deposition. Perhaps this was confirmed in one of the clinical trials taking place in Australia, where nearly 300 obese individuals experienced weight loss.

Besides, AOD9604 doesn’t affect IGF-1 and insulin levels, thus ensuring minimal risk of developing glucose intolerance and diabetes mellitus. With AOD9604, you don’t have to worry about hypercholesterolemia as well!

The good news is that AOD9604 is an FDA-approved drug as an anti-obesity drug, so you don’t have to worry about adverse effects at all. All you can expect is mild headaches, indigestion, nausea, swelling, etc.

AOD9604 can really be your go-to therapy for weight loss but make sure to use it at the proper dosages, or else a disturbed metabolic profile awaits you!

CJC 1295 + Ipamorelin Stack

This is the quintessential combination for Growth Hormone secretion. CJC-1295 is a Growth Hormone Releasing Hormone while Ipamorelin is one of the Growth Hormone Releasing Peptides.

Some studies are showing that using a GHRH and GHRP together will yield better results [2].

As this will massively increase your endogenous Growth Hormone release, you can expect similar results to taking pure HGH. Benefits include weight loss, muscle growth, and better body composition, and various human studies found that people just feel better on HGH therapy.

This is a very common peptide stack and is going to result in a better life, and potentially, your desired physique.

HCG Summary


Let’s face it. you might suffer from low testosterone at some point, whether that be due to age, drugs, or whatever illness. When this happens, you might need to use something to boost your natural Test production.

HCG or Human chorionic gonadotropin will act as an analog of LH (meaning a human-made version) and lead to an increase in testosterone production.

A nice addition of HCG is that it will increase and preserve fertility, unlike other TRT methods.

Glutathione Summary


I just wrote this article on Glutathione, and boy did I learn a lot. Glutathione is the main antioxidant in the body and is found in almost every cell. It is directly linked to glucose uptake, immune function, energy levels, tissue repair, and so much more [4].

Sure, it won’t be as interesting as a Growth Hormone Releasing Hormone, but your immune system is vital! You have so much shit inside you due to the lifestyle choices (Performance enhancing drugs) and you need to protect yourself.

Remember, if your kidneys give out, you cannot increase muscle mass ever again because you can’t eat a lot of protein…

What are Peptides?

Peptides seem hard to understand, but they aren’t. Peptides are simply Amino Acids that are bound together with Peptide bonds – hence the name. We do find them naturally in nature, such as Creatine or Collagen.

The Peptides for Bodybuilding are not always found in the way we use them. They can be used to offset a Growth Hormone deficiency, increase lean body mass, lower fat mass, improve metabolic health, and so much more.

Figure 1: Peptides like Human Growth Hormone can have a massve impact on the body

Most Peptides will have something to do with Growth Hormone, either being a Growth Hormone Releasing Peptide, or just one of the Growth Hormones.

This is because we naturally produce Growth Hormone, which will lead to muscle growth, fat loss, etc. Exogenous Growth is known as Peptide Therapy by HRT clinics, but can be used by athletes to overshoot the body’s production of Growth Hormone GH.

How Do Peptides Work?

Most Peptides will work by increasing IGF-1 or Insulin Like Growth Factor levels in the body. Usually, the Pituitary gland would produce Growth Hormone, resulting in IGF-1 being produced from the liver.

IGF-1 has been linked to improved muscle mass (slightly), improved body composition, better hair, better skin, and various other health benefits [5]. Peptides that will increase IGF-1 are pure HGH & IGF-1, Growth Hormone Secretagogues, etc.

Figrue 2: Studies have shown that there is a direct link between HGH and IGF-1 levels

Other Peptides will increase the fat burning properties of the body by increasing the levels of lipase, a hormone that will cleave fat from fat cells.

Because they differ so wildly from one another, you need to administer Peptides for the specific goal they were designed for. Some Peptides even result in increased appetite!

Human Growth Hormone Peptide

As mentioned, Growth Hormone is the McDaddy of all Peptides. This is why it is included in Peptide therapy by HRT clinics. It can lead to some lean muscle mass, while massively increasing fat loss.

HGH for Fat Loss

Growth Hormone GH will be used for fat loss due to its ability to increase Lipase levels in the body. Lipase will remove fat from fat cells and deposit them into the blood.

This means the body has easier access to these free fatty acids, meaning weight loss is easier to achieve. You do run a slightly increased risk of developing insulin resistance, but the use of Metformin should sort you out.

Optimally, you’d inject your HGH before doing fasted cardio. Bonus, Carnitine, and Clenbuterol play really well with HGH for fat loss.

HGH for Muscle Growth

While there are certainly some who use HGH for muscle growth, the truth is Peptides for muscle growth are somewhat disappointing.

They can cause cell growth, sure, but not nearly what Steroids would. That said, combining Steroids with Peptides, particularly Growth, is supposedly going to reduce the amount of Androgens you need.

Injecting Growth before going to bed is the best to improve muscle mass. Even using a Peptide stack like HGH with IGF-1 LR3 is going to be better than pure Growth when looking at muscle building qualities.

Best Peptides for Muscle Growth

Your best options are going to be HGH due to the massive amount of positive impacts it has on the body, or perhaps even IGF-1 LR3. This is a very long version of IGF-1, which could help the body build lean muscle.

That said, do not expect the same results as Steroids. There is a reason Steroids are not prescribed to healthy adults.

Best Peptides to Increase Growth Hormone

You are looking at Growth Hormone Secretagogues and Growth Hormone Releasing Hormones. Your money would be best spent on CJC-1295 and Ipamorelin, a classic combo, whether that be to burn fat or simply to increase Insulin Like Growth Factor.

Figure 3: Combining a GHRH and GHRP has been shown to have better HGH production results compared to using them on their own

Best Peptides for Fat Loss

HGH will reign king here, however, other Peptides such as HGH-Fragment or AOD 9604 are known to scorch body fat. HGH is still, overall, best for body composition.

That said, a few Weight Loss Clinics are experimenting with various Peptides to reduce Adipose tissue with the least amount of side effects possible.

Best Peptides for a Female

There really isn’t a great difference between male and female Peptide therapy. GH Secretion might be different from person to person, but there is no reason a female should take different Peptides compared to a male.

However, muscle gain will always be different between the two. Peptides for muscle growth can be used by both, but the doses will always be different.

For instance, IFBB Male bodybuilders use upwards of 10 units of Growth Hormone per day, Female Pros use 3 – 5.

Conclusion: Are Peptides just Expensive Water?

Peptides are all around us, consisting of the literal building blocks of protein – Amino Acids. Growth Hormone Secretagogues are great for the Gen Pop, and they won’t negatively affect the Pituitary gland or natural GH secretion negatively at all.

When it comes to bodybuilding, there are only a few Peptides that are worth the money. Growth, HGH-Frag, HCG, and some others are on the list.

Peptides will most often be used to reduce body fat, increase recovery, and perhaps increase energy production. You would use Steroids and SARMs for anabolism.

Peptides are reserved for very specific situations, so don’t expect them to change the world.

Are Peptides Amino Acids?

They “are” them, but they consist of Amino Acids in a specific pattern or sequence.

Best Peptides to Increase Testosterone

Your best options would be HCG, Kisspeptin, or perhaps Gonadorelin.

Best Peptides for Athletic Performance

HGH is always on the top of the list for anyone looking to boost a healthy lifestyle, and it will reduce body fat.

Do Peptides really work for muscle growth?

Peptides for muscle growth are often overrated. They do work for muscle growth, but not nearly as much as other PEDs.

Are Peptides better than HGH?

No. HGH will always remain on the top of this list because of its amazing ability to change such a massive amount of factors in the body.
