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.

Best Peptide Overall

Human Growth Hormone – HGH

The daddy. There really isn’t replacing just how effective normal Growth Hormone injections are compared to the other Peptides. Growth Hormone is vital to the human body, and some HRT Clinics might even prescribe it to the elderly.

Growth Hormone GH is known to have massive fat loss benefits, as well as some to increase skeletal muscle. It is also the base for recovery, by making sure connective tissue and bone density are on point. Hell, it could even increase skin elasticity!

Not as strong as Anabolic Steroids when it comes to increasing muscle cells but will (supposedly) increase sarcoplasmic growth.

Best Peptides for Bodybuilding
  • One Peptide to do all the work
  • Great for fat loss, especially abdominal fat [1]
  • This can lead to insulin resistance over time
  • Overuse can increase blood pressure and cause Edema
Best Fat Loss Peptide

HGH-Fragment or AOD 9604

Both of these are Peptides that are “related” to Growth Hormone but can still cause a significant reduction in fat mass. They will not be doing much for muscle growth, however.

These can both be used to improve your body composition. Fragment or Frag is a part of the Growth Hormone Amino Acid chain, particularly the last 15 amino acids (176-191).

AOD 9604 on the other hand is a modified version of those same amino acids (176-191), granting AOD the ability to manage injuries by increasing red blood cells and decreasing inflammation.

Neither Frag nor AOD will increase insulin resistance.

Best Peptides for Bodybuilding
  • Fat loss from HGH without the insulin resistance
  • Less chance of bloating
  • While there are studies on it, more are needed [2]
Best GH Stack

CJC-1295 with Ipamorelin

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 [3].

As this will massively increase your endogenous Growth Hormone release, you can expect similar results to take pure HGH. This means you gain muscle (slightly), lose weight, and you have better life quality.

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

Best Peptides for Bodybuilding
  • Does not suppress endogenous Growth Hormone production
  • All the benefits of HGH
  • Not as good as pure HGH
  • Can be irritating to inject so often
Best Peptide for Testosterone

HCG – Human Chorionic Gonadotropin

Let’s face it. You probably are going to be using some form of PED (Steroid or SARM) as a bodybuilder, and you would still want to ensure that you have natural Testosterone.

Sure, something like Nolvadex (Tamoxifen) is great, however, a Peptide Analog for Luteinizing Hormone like HCG is perfect to increase Testosterone in the Testes.

This has a direct link with spermatogenesis – the production of sperm. As a synthetic peptide, this is perfect to increase Testosterone levels.

It is also great for those looking to preserve fertility while on TRT.

Best Peptides for Bodybuilding
  • Increases Testosterone without too many adverse effects
  • Can increase Estrogen
Best Health Peptide

Reduced Glutathione

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…

Best Peptides for Bodybuilding
  • Potentially the best health supplement for a bodybuilder
  • Literally, none, buy it

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.

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.

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.

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.
