Peptides have been heavily researched for a while now, and they’ve gained serious popularity within the scientific community. However, like any new scientific field, concerns and questions arise. That’s why we’ve provided answers to some of the most frequently asked questions regarding research peptides.


What Are Peptides?

Peptides are naturally occurring short chains of amino acids, which are building blocks of proteins. Proteins are different from peptides in that they consist of long chain amino acids. They are smaller than proteins. The FDA considers any alpha amino acid polymer composed of 40 or fewer amino acids to be a peptide, not a protein.


What Are Peptides Used For?

Like amino acids and proteins, peptides have been used in research to produce muscle growth, fat loss, medical treatments, etc., in test subjects. Better yet, according to research, they have offered a variety of uses, such as muscle and joint repair, bodybuilding, skin care, inflammation reduction, blood clot prevention, and more. Besides their uses, research with peptides appear to produce results in less time; they’re more readily absorbed by the body because of their size and composition.


What Are the Best Peptides for Fat Loss, Muscle Growth, and Bodybuilding?

There are many peptides that have had some effect on fat loss, but research has pointed out one such peptide that has had a greater impact in that domain than others have – Growth Hormone-Releasing Peptide 6 (GHRP-6). This has been shown to produce anorexigenic effects in mice. This means that it suppressed the subjects’ appetite, thus aiding in weight loss, particularly in the mice that were fed high-fat diets. Other major peptides, such as CJC 1295, ipamorelin, and natriuretic peptide, also accelerate weight loss by helping boost the breakdown and release of fatty acids.

For muscle growth and bodybuilding, however, the GHRP-6 and natriuretic peptides mentioned above weren’t so effective. Instead, research has repeatedly found that collagen peptides and Growth Hormone Secretagogues (GHS) worked best to produce fat-free mass and cause significant increases in strength in subjects. GHS – such as CJC-1295, ipamorelin, or even a combination or blend of the two, have been shown to promote muscle growth by triggering the release of human growth hormone (HGH). Although it isn’t required, research does suggest that peptide supplementation produces the finest results when coupled with moderate resistance training and exercise.

Here’s a list of peptides that have been shown in studies to be effective for fat loss, muscle growth:


What Are the Best Peptides for Skin Care?

Skin has two primary properties that keep our skin strong and elastic – collagen and elastin. Collagen contributes primarily to skin strength, but may also play a role in preventing the skin from drying out. Elastin is what allows the skin to resume its original form after being manipulated.

Research has found that copper peptides, more than others, boost the formation of these two components, thus leaving the skin smooth yet firm. However, copper peptides alone aren’t enough to produce an anti-aging effect. Don’t worry, though, because scientists have answered that question for you as well.


What Are the Best Peptides for Anti-Aging?

Anything used to produce anti-aging effects needs to impact each of the factors that contribute to aging to begin with. These factors include joint health, cardiovascular health, and skin health. Here are some peptides that target each of those domains:

  • For skin health, the most useful peptides – according to research – are copper peptides. This is because they help boost collagen and elastin, the two primary components responsible for wrinkle prevention and skin strength.
  • For joint and cartilage health, research on isolated stem cells suggests a number of affinity peptides, such as the TGF-β affinity. According to the results, affinity peptides are able to reconnect particular cells and cell structures, all of which are partly responsible for cartilage formation.
  • When it comes to cardiovascular health, studies are pointing to natriuretic peptides (NPs), particularly the atrial NP and brain NP. These peptides are said to play a role in balancing heart function. That’s not all, however; due to their biological makeup, research supports their potential use as a healing agent.
  • Brain function declines over time – it’s inevitable, and it’s a major part of what makes the aging process apparent. In recent years, multiple studies (PDF) have found a peptide that aided in the treatment of cognitive impairments like Alzheimer’s Disease in rats; it is known as the Dihexa. As more research is being done on this peptide, they’ve shown that it offers significant improvements in the rats’ cognitive functioning.


Do You Need a Prescription to Buy Research Peptides?

These peptides should only be handled by qualified laboratory researchers and licensed professionals who plan on using those chemicals for research purposes, and as such they may obtain research peptides without a prescription.


Are Peptides Safe?

Many of these peptides are solely for research purposes, and their short and long-term effects are still being investigated. So far, healthy test subjects, primarily rodentia (rodents) and lagomorpha (rabbits & hares), have not presented any adverse effects.

However, subjects that were sick or allergic, as well as those that were administered higher than normal doses, presented with negative side effects – some mild, some more severe. They can have side effects and risks associated with them.


What Are the Benefits?

The administration of peptides on test subjects in numerous studies have presented the following positive effects:

  • Skin health: repairs, hydrates, and strengthens the skin.
  • Muscle growth and bodybuilding: increases lean muscle mass, improves strength, speeds up recovery, helps burn fat.
  • Anti-aging: speeds up recovery from injuries; keeps skin strong, smooth, and firm; repairs and maintains joint and cartilage health; prevents or slows cognitive impairments and neurodegenerative diseases.
  • Cognitive health: improves memory and focus, helps increase mental clarity and acuity.


What Are the Side Effects

Since research peptides and the ones found in food are much alike, serious side effects have not been a common occurrence in the test subjects. However, depending on how they were used in the studies, the most common side effects included:

  • Fluid retention
  • Increased blood sugar levels
  • Decreased insulin sensitivity
  • Increased appetite
  • Numbness or tingling
  • Hypertension
  • Reduced fertility
  • Kidney pain
  • Joint pain
  • Weight fluctuations
