Best Peptide for Building Muscle

Have you been working out on a regular basis, tried switching out the muscle groups you train, and are eating right but still not seeing the results you want to achieve?

You’re confused, frustrated, and feel like giving up. We’ve been there and it’s understandable how upsetting it can be. But maybe the reason why you’re not seeing changes is that it’s related to your body’s natural ability to create peptides.

Peptides are short strings of amino acids that help stimulate muscle growth, exercise performance, body fat loss, and exercise recovery.

As we age,  our bodies gradually decrease their production of peptides. This is why some bodybuilders and fitness enthusiasts are interested in taking collagen peptides to maximize their workout results. 

Lucky for us in this generation. Science has paved the way to create synthetic versions of peptides that can help us build muscle.

That being said, we listed below some of the best collagen peptides for building muscle based on their popularity and effectiveness. So, let’s go ahead and learn about the best peptides out there!

What to Look for in the Best Peptide for Building Muscle

Type of Peptide Supplement

Many health and even cosmetic products nowadays contain peptides due to their potential benefits, such as muscle building, anti-inflammatory, and anti-aging.

Some of the most common types of peptide supplements are collagen peptides and creatine peptides. 

CJC1295 and Ipamorelin

CJC1295 and Ipamorelin are two of the most popular peptides that help promote muscle building and improve recovery time. They can be given to a person one to two times daily at dosages ranging between 250mcg to 200mcg per administration.

If you’re wondering how long does CJC 1295 takes to work, it’s typically between 1 to 4 hours in therapy and when combined with Ipamorelin. Just like the CJC1295 peptide, the Ipamorelin helps build muscle.

Growth Hormone Releasing Peptide (GHRP)

A growth hormone-releasing peptide has gained popularity among bodybuilders for muscle gains. The growth hormone that is considered to be the most effective GHRP in the fitness industry is the GHRP-6.


Another peptide that works best for building muscle is BPC-157. It is known to improve the healing of various types of tissue from the muscle, nervous system, and tendon. 

BPC-157 has also been used by people who want to burn a few pounds.

Health benefits

Peptides have the ability to rewrite the body’s chemistry relationship in order to promote homeostasis (balance), anabolism (a process in metabolism where the simple molecules mix to generate complex molecules), and restoration.

Muscle growth and fat loss

Peptide supplements are known to increase strength and muscle mass. Meanwhile, peptide therapy helps a person drop fat.

The Verdict: Which One Should You Buy?

For what we consider the best collagen peptide in this list, in terms of its nutritional value, it would be the Vital Proteins Grass-Fed Collagen Peptides.

It contains 20 grams of hydrolyzed collagen and 18 grams of protein per serving. It dissolves fast without flavor so your taste buds won’t even notice there has been an upgrade in your drink. 

Disclaimer: It is always best to speak to your doctor about the right peptide and specific dosing for your goals.
