USA Peptides – Worldwide Shipping

Here’s everything you need to know about purchase peptides and buying peptides online. ResearchPeptides delivers the most accurate and medically-approved content on the web. 

Let’s learn more about what peptides are and where you can buy peptides in USA. 

What are Peptides?

Peptides Definition: short strings of amino acids comprised of 2-5 amino acids.

Essentially, peptides are smaller versions of proteins used both for research purposes and therapeutic purposes. Moreover, because they are smaller and more broken down than proteins, peptides are easier for the body to absorb. Consequently, they can effectively penetrate the skin and intestine, enabling them to enter the bloodstream more quickly.

Creatine peptides and collagen peptides are the most common peptide supplements available. Creatine has been shown to build muscle mass and strength, while collagen may benefit skin health. Others take peptide hormones to enhance their athletic activity.

Currently, human use of peptides is prohibited and should only be used by licensed researchers. Still, scientists are aware of the benefits of bioactive peptides and their effects on the body to improve human health.

What Do Peptides Do?

According to research, peptides function by providing the body with essential amino acids which get down-regulated as we age. For instance, insulin-like growth factor is produced naturally in the body. But when we get stressed and as we age, that production is reduced significantly. Therefore, peptides are vital for the human body to function effectively.

Some peptides act like neurotransmitters in the body, while others act like hormones. They control and influence how the body reacts to diet and physical exercise.

Take human growth hormone (HGH), for example — the body requires several amino acids in order to produce adequate amounts of that hormone. Let’s say your body isn’t making or absorbing enough of those amino acids. That would mean lowered growth hormone production, resulting in poorer recovery and performance.

It’s one of the main reasons fitness buffs take amino acid supplementation, otherwise known as peptides supplementation.

Unfortunately, the Anti-Doping Agency has banned peptides for therapeutic use due to conflicting research. But as studies continue, scientists learn more and more about what peptides do and how they can benefit the human body.

Recent research has shown that certain types of peptides offer potential anti-aging and anti-inflammatory properties.

Peptide Uses

Research indicates that benefits of bioactive peptides include lowering high blood pressure, reducing inflammation, diminishing microbes, and more. Let’s take a look at the top benefits of peptides, as reported by scientific research. Then we’ll move on to where to buy peptides in USA.

Increases Bone Mass

Apparently, animal research connects moderate intake of peptides with an increase in bone mass in growing rats. According to the study, peptides offered a useful means to counteract age-related bone loss.

Undoubtedly, more research is necessary — particularly on humans — to fully understand peptides effects on bone density. So far, studies look promising.

Slows the Aging Process

The protein collagen is naturally found in the skin, hair, and nails. Taking collagen peptides has been shown to improve skin health and significantly decelerate the aging process.

As per studies, peptides are linked to improved skin elasticity and hydration. This means it could be a possibly effective treatment for wrinkles. And because peptides also stimulate melanin production, a skin pigment, it could also protect the skin from sun damage.

Builds Muscle Mass

According to research, studies on older adults indicates that peptides can increase muscle mass and strength. In the study, participants combined creatine peptide supplement use with resistance training.

The results showed how effective peptides are for building muscle and strength.

Speeds Up Wound Healing

Scientists have long studied the link between peptides and wound healing. Studies demonstrate that peptides can reduce inflammation and act as antioxidants at the same time, improving the body’s ability to heal — and speed up healing.

Current research is placing the spotlight on antimicrobial peptides, which have shown to improve wound healing. However, researchers noted that having very high or low levels of certain antimicrobial peptides may contribute to skin disorders like eczema, rosacea, and psoriasis.

Growth hormone releasing peptides (GHRP)

GHRP causes secretion of larger amounts of GH in the body. They are available in the following types:


According to researchers, GHRP-6 can increase muscle mass, stimulate fat loss, and promote growth hormone release. It also helps in fighting inflammation and optimizing recovery. Additionally, it both encourages the pituitary to produce GH, as well as suppresses somatostatin which could jeopardize release.


GHRP-2 is stronger than the latter peptide, but it is used for similar purposes. While it hasn’t been shown to stimulate appetite like the other peptide, researchers have discovered it to improve lean muscle mass in testing subjects.


Ipamorelin stimulates the pituitary and also suppresses somatostatin. Not only is it a powerful growth hormone releasing peptide, it also doesn’t increase your appetite or cause your cortisol levels to rise.


Believed to be effective for muscle building, anti-aging, and fat loss, according to scientific studies, Hexarelin is one of the strongest peptides.

Insulin-like growth factor-1 (IGF-1)

These compounds target specific muscle groups and is available in different variants.


Comprised of 83 amino acids, this peptide adds an extra 13 amino acids to the sequence of the average insulin-like growth factor-1. In addition, it boasts a half-life of 30 hours, compared to IGF-1’s 15 hours. Recent studies have shown IGF-1 LR3 have positive effects on the human body including muscle mass growth, quicker recovery, and fat burning.

What are Bioactive Peptides?

Bioactive peptides (biologically active peptides) are short strings of amino acids used primarily for research, but also for therapeutic purposes. Most people are familiar with muscle peptides. While peptides are used in the bodybuilding world for muscle expansion, it is not legal to buy them for this purpose. So if you are looking for the best peptides for muscle growth, you will find them but you will need to state that you are buying them for research purposes only. That’s because peptides are not legal for human consumption.

What is Peptide Synthesis?

Peptide synthesis is basically the production of peptides. They are synthesized by linking two amino acids together which usually involved connecting C-terminus or carboxyl group to the N-terminus group.

Synthetic peptides are a critical element of biomedical research. Thanks to the synthesis of peptides, scientists are able to learn more about these proteins and their processes. Best of all, they get to discover all of their potential health benefits which could help in the treatment of numerous diseases and illnesses.

What is a Peptide Bond?

A peptide bond is a connection formed between two amino acids. In order to create peptide bonds, one amino acid needs to react with another amino acid. This will result in molecule water release, known as condensation reaction.

How are peptides used?

All products on this site are strictly for research purposes and so are not intended for human consumption.

How to Store Peptides?

In order to preserve the identity and integrity of peptides, you need to understand the best peptide storage practices.

By storing peptides correctly, you can help maintain peptides for years and protect them against oxidation and degradation. Poor storage, on the other hand, will quickly cause them to deteriorate.

Once you receive your US peptides, make sure they are kept cool and away from sunlight. If you intend on using them immediately or within the next few days, short-term refrigeration is acceptable.

While lyophilized peptides are best kept at room temperature for several weeks or more, you should store ready-for-use peptides in a freezer at -20C for best results. Prior to opening the packaging, let the peptide come to room temperature to prevent moisture affecting its identity.

Meanwhile, avoid contaminating peptides with air and moisture, as these factors can lead to peptide deterioration.

Peptide Storage Guidelines Summed Up:

  • Store in cool, dry, dark place
  • Avoid light exposure
  • Avoid exposure to moisture
  • Do not freeze and thaw more than once
