  • Last in line is Ipamorelin which is a growth hormone secretagogue (GHS). It increases human growth hormone (HGH) levels, resulting in all associated effects

What Are Peptides?

Peptides are short chains of amino acids that make up proteins. These peptides are based on the unique arrangement and sequencing of different amino acids which is responsible for many unique functional properties.

After the first synthetic peptide was introduced in the market, many other artificially synthesized peptides hit the market and brought a revolution!

These peptides are thought to interact with the proteins found in the human body. This leads to the regulation of various physiological and biochemical processes in the human body.

Glutathione Summary

Glutathione

Glutathione, an endogenous tripeptide with an amino acid sequence of cysteine, glutamic acid, and glycine, is often available at stores with the name GSH. This potent anti-oxidant molecule is produced by the liver and neuroglia in our body.

Glutathione plays a key role in detoxification and getting rid of all the oxidants and scavenger particles produced in the human body due to various biochemical processes. It is important to mention that one of the major roles of glutathione is to protect red blood cells, as they are more susceptible to oxidative stress.

Because glutathione levels decline as we age, this makes us more prone to developing cancers and other related disorders, so one can also correlate the role of glutathione in delaying the onset and progression of cancer.

HGH-Fragment 176-191

HGH-FRAG is a sliced version of Human Growth Hormone. Distinctly it comprises the last 16 amino acids sequence of HGH from the 191-long sequence of the latter. Chemically the peptide goes by C39H60N8O13. 

However, unlike HGH, the HGH-FRAG has quite a different working mechanism. One would think that being a spliced part of Growth Hormone, HGH fragments would also be conventionally working the same way. Nevertheless, the answer is no. 

Unlike its parent GH, HGH-FRAG does not bind to Growth Hormone Receptors (GHR) because it does not consist of all 191 amino acids. Thus, it can neither transcribe the formation of IGF-1 nor carry out any anabolic functions the way GH would. 

Research suggests that a three-week course with HGH-FRAG therapy in obese mice resulted in an approximate cut down of 50% in weight gain.

TB500 Summary

TB-500

Thymosin beta-4 is a small peptide with G actin-sequestering action. It is associated with the induction of angiogenesis and accelerated wound healing (10).

TB-500 is a synthetic version of the naturally occurring peptide LKKTETQ. The peptide segment (17)LKKTETQ(23) is the active site within the protein thymosin β(4) responsible for actin binding, cell migration and wound healing

Muscle fibers are made up of actin and myosin, which are contractile filaments. These filaments allow our muscles to contract and relax for mobility and carry out efficient metabolism and cell signaling.

TB-500 increases our body’s response to actin by increased reception of the protein by the peptide segment (17)LKKTETQ(23). This upregulation promotes increased cell growth, healthy cell proliferation, healing effects, and cell migration, particularly keratinocytes and endothelial cells.

TB-500 promotes angiogenesis which is the formation of new blood vessels. It builds up new blood vessel pathways for efficient blood supply to the wounds for increased healing. It also augments beneficial inflammation at the site of injuries.

BPC 157 Summary

BPC-157

BPC-157, or pentadecapeptide, is categorized as a body protection compound. It is composed of 15 amino acids in a very particular sequence that doesn’t exist naturally.

It is artificially synthesized in laboratories using the partial sequence of the body-protecting compounds isolated from gastric juices. Hence, it is one of the derivatives of the peptide found in human gastric juices.

The therapeutic effects of BPC-157 are exerted through multiple courses of action. One of the most common ways that BPC-157 acts as a therapeutic agent is by carrying out angiogenesis, which is the formation of new blood vessels. 

It does this by activating a protein called the “vascular endothelial growth factor” which initiates the formation of new blood vessels. This ensues in the organization of a healthy vascular network which gives BPC-157 its key regenerative and healing properties.

Another mechanism of action of BPC-157 is blocking the inhibitory growth factor called 4-hydroxynonenal, which is a negative modulator of growth. This allows the peptide to carry out effective healing of wounds, especially surrounding tendons.

Ipamorelin Summary

Ipamorelin

Ipamorelin is a pentapeptide (Aib-His-D-2-Nal-D-Phe-Lys-NH2), which displays high GH-releasing potency and efficacy in vitro and in vivo.Ipamorelin, a selective growth hormone-releasing peptide, has emerged as a promising agent for female fat loss.

Research shows that this compound can increase the body’s natural production of growth hormone by up to 30%. Growth hormone plays a pivotal role in fat metabolism, making its elevation crucial for effective fat loss.

For women, especially those over 40, natural growth hormone levels start to decline, leading to slower metabolism and increased fat storage. Ipamorelin’s ability to boost these levels can counteract this decline, potentially accelerating fat loss by up to 20%.

Moreover, unlike other growth hormone stimulants, Ipamorelin doesn’t increase appetite. This means women can benefit from its fat-burning properties without the counterproductive urge to eat more.

Additionally, a study found that participants using Ipamorelin experienced a 14% reduction in visceral fat over a 12-week period. Visceral fat, often termed “dangerous fat”, is linked to numerous health risks, making its reduction vital for overall health.

In summary, Ipamorelin offers a scientifically-backed approach to female fat loss, enhancing growth hormone levels, accelerating metabolism, and reducing harmful visceral fat, all without triggering increased appetite.

How Do Peptides Work?

Each peptide has a specific mechanism of action owing to its specific biochemical nature. And, with so much research and considering the market demand, we have peptides for almost everything.

Some of the peptides work by acting as growth hormone secretagogues (GHS), which eventually to growth hormone production.

On the other hand, some peptides play a key role in regeneration and improve recovery, wound healing, and rebuilding by stimulating specific processes such as angiogenesis.

Some peptides work best for anti-aging while others ensure that you have improved sleep.

Some peptides trigger weight loss by promoting fat oxidation as well as fat burning while some peptides ensure increased appetite and work similar to anabolic steroids.

To cut it short, because each peptide has a different working mechanism, it all comes down to your purpose of peptide therapy.

FAQs about Peptides

What are the risks of peptides?

A reaction at the injection site (redness, swelling, etc.), headaches, an increase in fluid retention, and flushing.

Are muscle peptides safe?

Currently, there are no data on the long-term health effects of taking peptides. However, most studies show that taking peptides for several weeks or months is safe.

Are peptides safer than HGH?

Peptides are not only much less expensive than HGH but much safer as well. Sermorelin and similar peptides stimulate the production and release of HGH from your pituitary gland.

Are bodybuilding peptides safe?

Using them may also cause health concerns, and they’re currently only approved to treat a handful of specific medical conditions.
