What is Ipamorelin peptide?

Ipamorelin is a small peptide sequence that binds to the receptor of ghrelin/growth hormone (GH) secretagogue, and research has shown the peptide to be extremely selective in its mode of action. Ipamorelin also does not induce the non-specific release of hormones like prolactin, thyroid-stimulating hormone, ACTH, luteinizing hormone, follicle-stimulating hormone, and cortisol. The high specificity of the peptide makes it an ideal model for the study of selectivity in receptor binding and also a potential candidate for therapeutic use.
It functions through interaction with cognate receptors on the target cell surface and mediates a cellular response. Ipamorelin induces secretions from the pituitary gland, promoting growth in animal study models. In addition, it not only triggers the expression of insulin-like growth factor-1(IGF-1) but also inhibits the secretion of somatostatin. Hence, the peptide influences the overall growth and repair of muscles and skeletal tissues in the body.

Research related to Ipamorelin pentapeptide

1. Bone Health
Prolonged use of glucocorticoids reduces bone density and can lead to fracture. Bisphosphonates, hormone therapies, and new monoclonal antibodies are used as alternative treatments though they come with their side effects and are often expensive. Ipamorelin thus happens to be an economic and physiologically safe alternative. Studies in rats have shown that the peptide not only prevents bone loss from glucocorticoid treatment it also induces up to a four-fold increase in bone formation. The peptide improves the bone mineral density of both existing and new bones. Additionally, it reverses side effects like muscle wasting and fat deposition in the body’s visceral organs.

2. Ipamorelin Peptide and Diabetes
Studies in murine models of diabetes have proven the efficacy of ipamorelin in promoting insulin release from islet cells of the pancreas. The peptide mediates the release of insulin through the indirect excitation of calcium channels found on the islet cells. The mechanism of ipamorelin action highlights the limitations of type 2 diabetes, helps develop novel therapeutic drugs, and strategizes better preventive measures.

3. Ipamorelin and Negative Corticosteroid Effects
Glucocorticoids are the kind of corticosteroids that are commonly administered to treat inflammation in diverse conditions ranging from cancer to autoimmune disease. Unfortunately, their adverse side effects restrict their use. Over long durations, a higher dose of these hormones is required to overcome their physiological ill effects. This treatment regimen hence can be near-fatal. Interestingly, ipamorelin has been observed to decrease the side effects of glucocorticoid use.

4. Muscle Growth
GH and GH secretagogues such as ipamorelin decrease the catabolic effects of glucocorticoids on muscles. Ipamorelin helps to reestablish the nitrogen balance and reduce nitrogen wasting in the liver of rats that were treated with glucocorticoids. Thus the molecule can single-handedly help to overcome both muscle wasting and loss of bone density in patients who require glucocorticoids.

5. Ipamorelin as Ghrelin Receptor Probe
The peptide binds strongly to the ghrelin receptor and acts as a selective agonist. Interestingly, the ghrelin receptor has been observed to increase cardiac failure and certain types of cancer, such as human carcinomas. Researchers have proposed using ipamorelin as a probe in positron emission tomography (PET) scans to help diagnose patients. In vitro reports have confirmed the possibility of using it. The next approach would be to perform in vivo study and optimize parameters for interpretation of the results.

6. Studied for Treatment of Post-Operative Ileus
Post-operative ileus (POI) is a common condition that often follows abdominal surgery. It is characterized by an inability of the patients to accept oral nutrition as the GI system stops functioning. It can involve pain leading to prolonged stay in hospitals and extended tenure required for recovery.
Ipamorelin has been studied in multiple proof-of-concept clinical trials to determine its efficacy to reduce POI. It was found to shorten the time of uptake of the first meal by about 12 hours in POI patients. However, the trials were discarded as the company conducting them decided the efficacy of the drug to be insufficient for a viable product. However, the use of ipamorelin in combination with other therapies might be more useful in treating POI.
Some of the research observations are as follows:
– Residual radiolabeled food remaining in the stomach of rats with POI is less after the use of ipamorelin, even when compared to rats without POI.
– When administered ipamorelin, the geometric location of the food is observed to be similar for both rats without POI and those with POI
– The radiolabeled food is located more distally in the GI tract and is similar to rats without POI, after ipamorelin is used on rats with POI.

This Peptide Is Neglected in Research

The peptide is still not studied extensively despite having multiple benefits, including the treatment of POI. One of the reasons has been the decision of the company to discontinue active research on the drug. Apart from therapeutic impact, the molecule can be used to study various aspects of human physiology and disease biology in detail. A new approach of study using cutting-edge technology might shift focus back to this novel peptide.
The peptide has exhibited moderate side effects, low oral bioavailability, and excellent subcutaneous bioavailability in mice. The dosage (per kg) in mice does not scale to humans.

    I accidentally ordeed the wrong item. Thanks for reshipping for free!

  4. Bailey Maguire

    So far so good. Never had any issues buying here. I really appreciate the ease of this website and the smooth transaction. Was not too hard to get around and had your standard check out method. Got to use a discount code they sent me not too long ago as well. It’s estimated i’ll get my peptide within 2 days of my order too.

  5. Tamara Qonita Mahadi

    Thanks for the fast service and great peptides!

    Excellent peptides, One of the best I have used in the last few years. Did not effect the outcome of my research too much but that typically would take a while to show.

  15. Karmen Wheeler

    Everything came packaged safley. I only wish the box was different as I had a hard time figuring out what it was I had just received. Side note, everything came faster than expected.

  26. Vincient Thomas

    Taylor is extremely helpful and goes above and beyond to help you out and solve any issue you’re having. Very happy to have worked with them. My peptides had issues with customs and thus I was not going to get them on time. I was on a tight schedule and dealing with companies like this can be a headache. It was nice to deal with Taylor who actually helped and did whatever they could to help me out as well and not leave me hanging dry. We ended up canceling and replacing the order but up until then they did everything they could to help get ahold of the shipping company and get this sorted.

  27. Lee Wong

    Happy with the service and Peptides. Been looking for a good peptide supplier for a while now and I feel like I found the place for me. Nicely priced as well!

  28. Tom King

    Ipamorelin is one of the most underrated peptides and I am glad I gave it a chance for my research.
