Peptides For Muscle Growth: A Definitive Guide

Peptides For Muscle Growth: A Definitive Guide

The performance supplement market has seen major changes in the last 20 years. The main source of these changes has come from SARMs and Peptides which are in so many ways far superior to traditional anabolic steroids.

First of all, they have far fewer, and in some cases no known side effects. That is something that has always been a huge problem with other hormone based enhancers.

Two of the main reasons people turn to supplements is to either build up more lean muscle mass or reduce BMI. For this article, we are going to focus more on the function of muscle growth and we’ll explore how certain peptides help in this process.

You’ll also learn more about these effects compared to other available products, so that you can make a better informed decision.

Let’s start with a general introduction.

What Are Peptides?

Essentially, they are very similar in nature to proteins. Both peptides and proteins are made up of chains of amino acids in different lengths. Anything with more than 50 amino acids is generally classified a protein, while anything below is a peptide.

Dependent on the size and structure of the peptides, they will bind to specific receptors and enzymes in the body to trigger different processes. Many peptides these days are synthetic in nature, but natural ones are also available and quite commonly used in medical treatments as well.

The majority of these drugs have a combined effect on muscle production and fat burning. This creation of lean body mass is why they are most commonly used and also where they are most effective.

The main trigger in the body is to increase the amount of human Growth Hormone (hGH) which is directly responsible for increased metabolic rates and muscle growth. Another positive effect and clinical use is an increase in bone density.

However, it’s important to understand that there are maximum levels of GH the body will accept before starting to take counter action to reduce it. That’s why dosage and timing of these drugs is very important to not end up wasting it.

How Are They Different From SARMs?

Many people often mistakenly think that they are basically the same. While the benefits are indeed very similar, there are some important differences. Not just when it comes to the side effects, which we’ll get to below.

First thing to note, is that the majority of SARMs these days can be orally taken which for many people is a big plus because it doesn’t require needle injections. Peptides on the other hand are most often supplied in powdered form and require mixing with bacteriostatic water and an injection.

The other important difference is that most SARMs usually only cause one specific physiological trigger, e.g. muscle growth. Very few are less selective and also reduce body fat at the same time. This means that SARMs often have to be stacked to achieve broader results.

Peptides are also more prone to cause some side effects, so let’s take a look at those next.


What Kind Of Side Effects Do They Have?

Because of the growth hormone release there are certain natural processes that happen in the body as a response. Many peptides will increase the cortisol hormone levels which is how they trigger fat burning. However, this also increases blood sugar levels which can be harmful.

Proclatin hormone levels are also likely to increase which has a direct reducing effect on the levels of oestrogen and testosterone. This has very different results in men and women, but is commonly associated to mood swings and also a reduced libido, or sex drive.

Some clinical trials have also shown that peptides and the resulting growth hormone spikes can cause some nausea and light-headedness. These are common side effects that are fully reversible with lowered doses.

Overall, peptides do have a few more side effects than SARMs, but they are far less harmful than traditional steroidal hormone treatments.

What Are The Best Options?

When it comes to using peptides for muscle growth there are two products that are most suitable. The majority of others available have a combination effect of muscle growth and increased fat burning.

While this is a great combination there are still times in a training cycle where the main priority is bulking up. And for that purpose there are two stand out products.


This synthetic peptide is very effective at increasing growth hormone levels and triggering some significant increases in muscle fibre production. With the added benefit of Drug Affinity Complex (DAC), it ensures that a peak level of GH is maintained for a much longer period.

The result is that the GH release will work during your workout and also in post training recovery to help repair damaged tissue.


This is quite a unique product in that it goes beyond just muscle growth. It enhances the body’s ability to regenerate damaged cells and promotes a much younger general appearance.

Bone density is also positively affected meaning that your overall strength and stamina improves.

Final Thoughts

If you’re new to performance supplements, then peptides are a great way to start boosting muscle growth and reducing fat. For those looking to just bulk up, there are some products available that will help.

Generally speaking though, they are more suitable for a combination with fat burning, which might be an added bonus to consider.
