Peptides

What Are Peptides?

Amino acid strings, sometimes referred to as peptides, are the “building blocks” of proteins. Peptides are essentially small proteins, ranging in length from 20 to 100 amino acids. Peptides are crucial components of several essential bodily activities that your body produces.

For example, the peptide hormone insulin, which has a length of 51 amino acids, aids in your cells’ uptake of carbohydrates from your diet for usage in metabolism and storage in your liver.

Since 1921, scientists have been trying to create peptides as remedies for various illnesses. Insulin, also known as a synthetic peptide, was really the first peptide that scientists produced in a lab and has been used to treat type 1 diabetic patients since 1923.

Peptide medications may be superior to other medications in some ways because they might:

• Be simpler for your body to transmit to the appropriate places.
• possess less adverse consequences
• You can feel more secure knowing that when they break down, your body can recycle the amino acids that are left behind.

Certain peptides may also improve your muscles, skin, and maybe even your weight, according to studies. Thus, for many years, businesses have been including them in over-the-counter food supplements and skin care products.

Peptides vs. Proteins

Peptide bonds hold the strings of amino acids that make up peptides and proteins together. Though the terminology isn’t used properly, the key distinction is that peptides are shorter sequences of amino acids than proteins.

Proteins are defined by most scientists as chains containing more than 100 amino acids. Additionally, scientists refer to peptides larger than 20 amino acids as polypeptides and oligopeptides for peptides that are between 10 and 20 amino acids long.

Benefits of Peptides

Numerous distinct peptides are produced by your body, and each one has a unique purpose. In the lab, scientists can also create synthetic peptides. For many years, businesses have been using peptides in skin care products. Some peptides may have the following advantages:

Peptides For Anti-Aging

One of the primary components of your skin, muscles, bones, tendons, ligaments, and other connective tissues is the protein collagen. All these components have structure, strength, and elasticity thanks to collagen.

Your body produces less collagen as you age, and the collagen you do have is broken down more quickly. Your muscles, bones, and tendons contract, stiffen, and weaken as a result, and your skin ages and sags.

Injections of collagen can help fill in creases and plump up your skin. However, studies also suggest that oral collagen supplements, particularly for those over 30, may maintain the elasticity and moisture content of your skin.

They could also assist those suffering from osteoarthritis, or “wear-and-tear” arthritis, which is often brought on by age, feel less pain and have better joint function.

Because your body cannot absorb collagen in its whole, it is often hydrolyzed into smaller collagen peptides, or around three to four amino acids, which are then used in supplements.

These oral supplements are available at drugstores, health food stores, and certain grocery stores as tablets or powders.

Another peptide that may help your body produce more collagen and elastin, two proteins found in your skin, is copper (GHK-Cu) peptide. It also helps heal damaged skin and functions as an antioxidant.

According to research, GHK-Cu in face and eye creams may enhance skin hydration, suppleness, and thickness while reducing wrinkles, age spots, and lines (hyperpigmentation). It could also promote thicker hair growth.

Copper peptide is included in hair serums and skin care products including lotions, creams, and serums. retail shops, internet, spas, and beauty supply outlets.

The FDA outlawed copper peptide injections in September 2023 after discovering contaminants in the liquid form that caused adverse responses in certain individuals. Previously, these injections were offered in spas and wellness centers.

Palmitoyl pentapeptide-4, commonly known as Matrixyl, is a synthetic peptide that may also encourage your body to produce more collagen, which may smooth out wrinkles and dark circles under your eyes. Copper peptides face creams and serums containing Matrixyl are available at the same locations.

Peptides For Skin

Your skin contains a variety of peptides that your body produces, such as antimicrobial peptides (AMPs), which support wound healing, bacterial defense, and the development of a robust skin barrier. Psoriasis, eczema, rosacea, or acne may be present if your skin produces an excessive or insufficient amount of AMPs.

For those suffering from psoriasis or eczema, lotions and serums containing AMPs may help rebuild the skin barrier and reduce swelling and redness.

Additionally, AMPs may aid in the better healing of ulcers and sores in diabetics as well as prevent germs from entering your pores and producing acne. If you would want to try one of these, speak with your doctor as most of these medications require a prescription.

Peptides For Muscle Growth And Weight Loss

Supplements containing collagen and creatine may stimulate the development or repair of muscle. development hormone secretagogues (GHS), a class of synthetic peptides believed to be connected to muscle development, may be harmful and unlawful.

For example, they might raise blood sugar levels and lessen your body’s sensitivity to insulin. In addition, all GHS supplements are prohibited by the World Anti-Doping Agency if you are participating in an athletic competition.

Peptides For Hair Growth

Certain peptides could promote healthier, thicker, and longer-growing hair. For example, GHK-Cu, a collagen peptide, may help stimulate greater hair growth in those with pattern hair loss.

This is available for purchase as a serum that you may use on your hair. Additional choices include folitin, another serum that you may apply straight to your scalp, and collagen peptide supplements in the form of tablets or powders.

Peptides For Bone Loss

Supplements containing collagen peptides could also aid in increasing bone mineral density. In one study, following menopause, individuals designated female at birth (AFAB) had higher bone mineral density in their upper back and upper leg bones when they took daily collagen peptide supplements for a year. Additionally, the FDA has authorized a few peptide medications for the treatment of osteoporosis.

Peptides For Testosterone

By encouraging your body to produce and release follicle-stimulating hormone (FSH), gonadotropin luteinizing hormone (LH), and gonadotropin-releasing hormone (GnRH), some peptides may help raise your testosterone levels.

The major ways your body produces testosterone are through these three hormones. Gonadorelin and kisspeptin-10 are two examples of such peptides. Kisspeptin-10 raised average blood testosterone levels 24 hours after injection in one study.

In another research, individuals assigned male at birth (AMAB) who had low testosterone levels due to insufficient GnRH production were able to regain their fertility when their testosterone levels were raised with gonadorelin.

Peptide Therapy

The application of peptides to modify or enhance the function of specific bodily systems is known as peptide therapy.

To increase their body’s growth hormone production, for example, some sportsmen take growth hormone-releasing peptides. After rigorous training and competition, this can aid in the recovery of their bones and muscles.

Peptides can be employed in a variety of ways, depending on the type:

• By oral means (supplements for food)
• By applying topically (topical) or transdermally (transdermally), smoothing
• By injecting them via your nasal (orifice)
• 4 via injection at a wellness center or your doctor’s office (peptide injection)

Peptides are employed in many forms depending on a multitude of criteria. For example, the majority of peptides lack stability and simply degrade when added to a cream or supplement.

Oral supplements containing peptides also don’t enter your bloodstream intact since they are broken down similarly to food. Because injecting peptides straight into your bloodstream facilitates their better absorption by your body, peptide injections are frequently performed.

Peptide Supplements

Peptides are available as dietary supplements in the form of protein shakes or tablets. For example, the manufacturers say they can speed up weight reduction and fat removal, help you gain muscle, or heal after an exercise.

However, most of these assertions lack strong concrete evidence to back them up. Furthermore, since supplements include entire peptides that are often fully converted into amino acids by your digestive system, it’s unclear how efficiently your body can absorb them.

The following are a few peptides that are available as supplements:

• The peptide creatine is supposed to aid with muscle growth.
• Collagen peptide is said to prevent aging and improve the health of your skin, hair, and nails
• Follistatin is purported to aid with weight loss and muscle growth.

Peptides in Food

Many foods, especially those that are excellent providers of amino acids, naturally contain peptides. Examples of these foods include:

• Meat
• Seafood and crustaceans
• Lentils with beans
• Soy
• oats
• Flaxseed
• Hemp seeds
• Wheat

Peptides Drugs

Drugs for a wide range of illnesses and ailments are also made from peptides. Currently, over 100 peptide medications have FDA approval in the United States. Among these medications are, for instance:

• For advanced prostate cancer, use Degarelix (Firmagon) and Abarelix (Plenaxis).
• Kyprolis (carfilzomib) for multiple myeloma
• Fuzeon, or enfuvirtide, for HIV
• For type 2 diabetes, there are several options such as Exenatide (Byetta), Liraglutide (Victoza), Lixisenatide (Adlyxin), Albiglutide (Tanzeum), Dulaglutide (Trulicity), and Semaglutide (Wegovy, Ozempic).
• Use linaclotide (Linzess) to treat irritable bowel syndrome (IBS) with constipation as well as chronic idiopathic constipation.
• For malabsorption, which is the condition in which nutrients are not adequately absorbed from the stomach and intestines, use teduglutide (Gattex).
• For osteoporosis, teriparatide (Forteo) and abaloparatide (Tymlos)
• Teriparatide (Forteo) and abaloparatide (Tymlos) for osteoporosis

These medications are strictly controlled by the FDA and have undergone extensive study, in contrast to certain supplements and cosmetics. If you have any questions about using a peptide medication, ask your doctor.

Side Effects of Peptides

When taken as prescribed by a physician, peptide treatment is usually safe. Peptide supplements are not expected to have major negative effects for the majority of healthy individuals. When purchasing and utilizing peptide supplements, use caution as the FDA does not evaluate supplements prior to sale.

Taking supplements should be done with extra caution if you:

• are breastfeeding or expecting a child?
• possess a health issue
• Do you take medication?

Before beginning to use peptide supplements, discuss your options with your physician.

The following are a few potential peptide supplement negative effects:

• Allergic responses that cause swelling, hives, or trouble breathing
• Heart issues such as palpitations (fluttering or hammering pulse), excessive blood pressure, and rapid heartbeat
• gastrointestinal issues, including diarrhea, vomiting, and nausea
• cognitive issues such as tiredness, headaches, and dizziness
• Skin rashes and sensitivity (if you use peptides topically)

Types of Peptides

Peptides come in two varieties:

• Exogenous peptides: the body produces them. The body spontaneously releases them from proteins and secretes them from cells.
• Exogenous peptides: are created or synthesized by methods other than those found in the body, such as organic synthesis, biosynthesis, or the enzymatic hydrolysis of proteins.

Peptides are classified according to the length of the amino acid chain and whether or not they originate from plants or animals. Dipeptides, for instance, are composed of two amino acids, oligopeptides of a few, and polypeptides of twenty to fifty amino acids.
